Camcorder Formats
The first consumer camcorder was released in 1983 by Sony, known as the Betamovie BMC-100P (Betamax). In 1984-1985, the
VHS-C and full size VHS camcorders arrived.
The following table summarizes the basic formats
for the consumer camcorder market. VHS camcorders are not sold anymore and 8mm has been replaced by Hi8 and Digital8 which are now out of date.
MiniDV was the most popular until newer formats came along. The newer formats include
mini DVD, although this format has faded, hard disk drive models (HDD up to 120GB) and High-Definition models,
both disk-based and flash-memory card based.
Memory card capacity goes from 1GB to 2TB and more.
Flash memory camcorders, which replaced tape-based camcorders, DVD, and hard drive models, were popular from about
2008 to 2012, before fading as smartphones became the dominant video device.
While flash storage (like SD cards) matured, dedicated camcorders were superseded by HD recording on smartphones
and high-end mirrorless cameras starting around 2010-2015.

Video Formats
In the
last few decades, videotape has progressed through no
less than 20 different (and incompatible) formats. Although
this may be one of the prices we have to pay for
progress, it has also added confusion to the video
recording process.
For camcorder use, the VHS format is obsolete as the
size and bulk of the camera is cumbersome for most
people. VHS-C is smaller but still records at 250
lines of resolution. Sony's analog 8mm and Hi-8mm
camcorders use even smaller videocassettes.
(MiniDV or DVC) record at almost 500 lines
resolution.
The DVD
based camcorders have the same 500 line resolution and
record on 8cm DVD. Sony, Panasonic and Hitachi have
been the main producers of DVD camcorders for consumers.
With the advent of HDTV with 1080 lines of resolution,
several camcorders with High-Definition recording
capability have been released. Called HDV they use a
MiniDV videotape cassette. The newer formats include the hard disk-based (up to 120GB)
and the flash memory card based camcorders. These can record in standard definition or even high definition.
The flash memory card camcorders have no moving parts to wear out like tape or disk and can record hours of video on a thumb-sized chip.
Camcorder Formats
The following is a list of the
basic consumer camcorder formats and their features. Keep in mind,
these video formats are for the most part (except Sony 8mm) physically and
technologically incompatible, meaning you cannot record or
play one format on another type camera.
1.) VHS - half inch wide
tape in full size cassette, today, virtually obsolete in
consumer camcorders but still used in home VCRs.

Panasonic full size VHS camcorder
VHS camcorders make it possible for you to immediately
watch the tape on your home VCR, not worrying about
adapters or wires, you just pop the tape from the camcorder and into the VCR.
A standard T-120 VHS tape has a
recording time of 2 hrs (8 hrs. is possible today), and the resolution is about 250 lines.
VHS is an analog format and therefore does not have any of the
features that you get with a digital format.
2.) S-VHS - tapes can only be played by attaching the camcorder to
your VCR or by using an S-VHS VCR, as they are not
compatible with standard VCRs. The camcorder has a
maximum recording time of 2 hours. The S stands for
super, as the resolution jumps from the VHS standard
of 250 lines to around 400 lines.
3.) VHS-C - smaller version
of VHS, introduced in 1982 by Panasonic. This camcorder uses VHS tapes that are smaller than the
standard VHS size, and can be played in your home VCR by
putting it in a VHS-C adaptor. The maximum recording time
is 90 minutes in EP mode, and the resolution is the same as
regular size VHS tapes at 250 lines.

Panasonic VHS-C Camcorder

Camcorder VHS-C format by Panasonic
To compete with the smaller tape size of
8mm, VHS-C was created. The "C" stands for "Compact" and,
although the tape width and the hub of the tape spool is the
same size as VHS, the rest of the tape case is smaller.
Adaptors are available which allow you to use a VHS-C tape in
a standard, full-size VHS videotape machine.
4.) S-VHS-C - JVC improved their system when they
created "S-VHS-C." The "S" stands for "Super" and indeed it is
a massive improvement over VHS. Although S-VHS-C is the exact
same size as VHS-C tape, S-VHS-C delivers about 400 lines of
resolution. Almost double the quality of standard VHS-C tape.
S-VHS-C is also "backwards compatible" with VHS-C, meaning
that any S-VHS-C videotape player can also play back standard
VHS-C tapes. However, VHS-C can NOT record or play back
S-VHS-C.
5.) 8mm - 8mm
camcorders are more compact than VHS. The tapes
are incompatible with home VCRs and you have to wire
the camcorder to your television to watch them. 8mm
can record for up to 2 hours in SP mode or 4 hours in
LP mode, and they have a
resolution of 270 lines. Sony Corp. released 8mm - not to
be confused with 8mm film. 8mm videotape has slightly better
resolution than VHS, however, the tape itself is only about the
size of a standard audio cassette. The convenience of such a
small physical size made the format very appealing.
The first Sony 8mm camcorder sold in the USA was the Sony CCD-V8, released in 1985.
The Sony CCD-TR55, released in May 1989, was a revolutionary "passport-sized" 8mm Handycam,
recognized as the world’s smallest and lightest video camcorder at the time.

The Sony CCD-TRV series was specifically known for featuring fold-out (or flip-open) LCD screens,
often marketed under the "Handycam Vision" branding.
TRV vs. TR: The "V" in CCD-TRV generally stands for Vision, representing the addition of a color or black-and-white LCD screen.
The standard CCD-TR models typically only had the traditional eyepiece viewfinder.
These camcorders were prevalent in the late 1990s through the mid-2000s, with models like the CCD-TRV65 (1998) and later
models like the CCD-TRV138 (2005) featuring the flip-out screen.
The LCD screen was primarily used for viewing while recording, as well as reviewing tapes in playback mode.
While most TRV models featured a LCD screen, the size of the screen (typically 2.5 to 3.5 inches) varied.
What does the XR stand for?
During the Sony camcorder analog Era (Video8-XR / Hi8-XR)
Early 1998, "XR" indicated a roughly 10% improvement in luminance detail for 8mm and Hi8 tapes,
resulting in a slightly sharper picture.

6.) Hi8
- Hi-8 camcorders use 8mm tapes but the video tape formulation is different from video8 8mm tapes.
Hi8 tapes use superior magnetic particle formulation.
The tapes have a maximum recording time of 2 hours. Hi-8
is about the same resolution as S-VHS, around
400 lines. Sony bettered their 8mm format by
creating Hi8 or High-Band 8mm which has 400 lines of
resolution on a tape which looks physically identical to 8mm video8 but provides better resolution.
Hi8 is backwards compatible with 8mm and any Hi8
camcorder can play 8mm video8 tapes. However, 8mm can NOT play or
record Hi8. Hi8 became a very popular format and Hitachi, Canon, Sony and Sharp all
had Hi8 cameras available. Sony was still producing Hi8mm camcorders up to 2005 and they worked well.
The first Sony Handycam to feature a fold-out color LCD screen was part of the Sony Handycam TR series,
appearing on high-end Hi8 models in the mid-1990s, with color LCD screens becoming a standard
feature in 1992. The later TRV series, revolutionized viewing by allowing users to watch recordings directly on the camera screen.

What was the last Hi8 camcorder?
The last Hi8 camcorder (the Sony CCD-TRV238) and the last Digital8 camcorder (the Sony DCR-TRV280 (NTSC) / DCR-TRV285 (PAL))
were both discontinued in 2007, ending the 8mm format's 22 year reign.
7.) Digital8 - The
digital8 format records images digitally, and use
8mm (Hi8) cassettes. These tapes are incompatible
with the standard VHS VCR. The camcorder can
record up to 1 hour of digital information, and has a
resolution of up to 500 lines.
Both Hi8 and Digital8 use the same Hi8 tape but since Digital8 records twice as
fast, only 90 min. can be recorded on each tape. Low-band formats have less
impressive picture and sound quality, which also does not
stand up well to multiple-generation duplication (making a
high-band model essential if editing and copying is an
important factor for you). Low-band picture resolution varies
from around 240 to 250 horizontal lines of resolution compared
to the 500 lines offered by many digital models.
• Video8 (analog)
• Hi8 (higher-resolution analog)
• Digital8 (digital recording)
In March of 1999, Sony released the
Digital8 format, which is basically an 8mm camera with digital
capabilities. The advantage to it is that you can record
digitally and even play back your old analog 8mm or Hi8 tapes.
Not every Digital 8 camcorder with 8mm has the ability to playback Hi8 tapes.
This feature is often referred to as “backwards compatibility” and is only available in specific models of Sony camcorders.
For example, the Sony Digital8 camcorders below cannot playback video8 or Hi8 analog tapes previously recorded.

8.) MiniDV - The MiniDV
format has a wide selection for retail camcorder sale and is
very popular due to the small size and digital capabilities.
These camcorders record images digitally, and use much smaller
tapes compared to VHS or 8mm. The tapes must be played back
through the camcorder or to your TV. Their maximum recording
time is up to 2 hours. These digital camcorders have higher resolution, starting at
500 lines which is excellent resolution giving you
sharp, clear video. These camcorders are loaded with extra new
features, like stereo audio, which are not available on older
model formats.
Originally,
DV was called DVC (Digital Video
Cassette) and uses a 1/4 inch (6.35mm) metal evaporate tape.
The video is the same quality as D-1, D-5, or Digital Betacam
video -- 720 pixels per scanline. In late 1995, Sony released
two DV cameras and Panasonic released one. DV tapes are about
one tenth the size of standard VHS tapes and deliver over
twice the resolution - 500 lines. DV is also purely digital, not analog like VHS.
Although DV
uses tape, it is digitally recorded, providing the sort of
improvement you have when you compare a CD or DVD over a VHS
tape or a vinyl record album. DV records its audio digitally
as well, in 16-bit digital - the same as a CD. When you copy a
DV tape, it is an exact clone of the original too.
Using the i.Link (IEEE 1394) cable, you can transfer your digital
video from your MiniDV camcorder tape to a DVD. Many MiniDV
camcorders have removable solid-state memory chips to record
still photos. Get prints of your photos just like a digital
camera.

9.) MicroMV - Sony's super small video tape format, see MicroMV
for more on this format.
MicroMV technology is unique. Be careful of
incompatibilities. Previous digital
formats, MiniDV and Digital8, used a compression scheme that
operated on each frame of video independently, essentially treating
each frame as a separate still image. The MicroMV MPEG-2 video on
the other hand, is not necessarily compatible across any previous
format or even different MPEG-2 systems. MPEG-2 works across 15
frames, retaining and compressing only the changed video information
on frames 2 through 15. This video standard won't work with all
i.Link ports. The audio recording technology is also unique. The
small size makes for physical portability like no other camcorder but the
cost was relatively high. (The MicroMV format is not being marketed
by Sony anymore.)

10.) DVD - which includes
DVD-RAM, DVD-R, and DVD-RW, first introduced in 1997
by Hitachi, using 8cm optical disc media.
The 8cm DVD is the mini version of the full sized 12cm optical disc, DVD and CD.
Direct DVD recording: Records directly onto 3-inch DVD-R and DVD-RW media, offering resolutions comparable to MiniDV.
Playback convenience: Recorded DVD media is compatible with most current DVD players and PCs for easy viewing.
Integrated still image capture: Features a 1-megapixel CCD imager capable of capturing JPEG still images up to 1152 x 864 resolution.
Uses 1.47GB single side and 2.9GB dual side mini discs as opposed
to the 4.7GB standard full size DVD disc.
About the same camera size as MiniDV camcorders with similar
technology. Ability to play DVD-R media in most DVD video players.
Has recording quality settings for HQ, SP and LP giving 20
min. to 60 min. recording time per side. Hitachi, Panasonic
and Sony have several DVD models.

Sony DCM-M1 MiniDisc Camcorder

In 1999, Sony introduced the DCM-M1, a Minidisc Recorder using the MD Data2 format and introducing touchscreen editing. The
on-camera video editing random access features are something that video tape based camcorders could never do.
This camcorder can record only 10 minutes of video in standard record mode, or 20 minutes in LP mode.
Records 400 lines of horizontal resolution. Original retail price was $2,299.
11.) HDV High-Definition - tape-based 1080i
high definition video recording and playback. Uses HD DVC
videocassette.

Sony HDR-FX1
The Sony HDR-FX1 is a 3CCD prosumer camcorder that introduced 1080i HDV high-definition recording
to the consumer market, utilizing standard MiniDV tapes.
Record all your memories in true high-definition video. The
HDR-FX1 is capable of recording and playing back both High
Definition and Standard Definition video recorded on standard
MiniDV cassettes. In 2006, Sony introduced a much smaller
HDV camcorder, the HDR-HC3, which gives you 1080 resolution in a
palm-sized camera.
The Sony HDR-HC3 is a compact, high-definition (1080i) consumer camcorder released around 2006
that records on MiniDV/HDV tapes.

• HDMI output
• audio/video output - composite and component video
• i.LINK® jack
• USB interface
Uses MPEG-2 compression to fit a full hour of video on a MiniDV tape.
You transfer both HD and SD video using iLink (Sony's brand name for an IEEE 1394/FireWire connection).
The camcorder can downconvert HD content to standard-definition during transfer, useful when the destination
is a DVD. No included software for transferring or editing.
12.) HDD - hard
disk drive built-in. Records video to hard disk.
Hard disk drive (HDD) camcorders, popular in the mid-to-late 2000s
(e.g., Sony Handycam SR series, JVC Everio), typically used 1.8-inch hard drives.
Platter Diameter: The magnetic data storage platters inside these drives are approximately 1.8 inches in diameter.
Alternative Sizes: While 1.8-inch was standard for compact camcorders, some larger or earlier models
may have used 2.5-inch drives, though these were less common in handheld, consumer-grade HDD camcorders.
Performance Constraints: Due to their small size, 1.8-inch drives commonly operated at lower speeds (3,600 to 4,200 RPM),
leading to lower transfer rates compared to 2.5-inch or 3.5-inch drives.
Capacity: Typical capacities for these camcorders ranged from 30GB to 120GB,
as seen in models like the JVC Everio GZ-MG155 (30GB) and Sony HDR-SR8 (100GB).
These drives were designed to be lightweight and shock-resistant for portable video recording,
but have largely been replaced by flash memory (SD cards).
JVC GZ-MG20U, 30U, 40U, 50U Hard Disk Camcorders released in 2005 were the first HDD (1.8 inch drives) camcorders.
30GB model had 7 or 14 hours recording time with direct access to videos unlike tape based camcorders.
The first HDD-based High Definition (HD) camcorders arrived shortly after, such as the JVC GZ-HD7 and Sony HDR-SR1 in 2006.

Sony HDR-XR260V High-definition camcorder with 160GB internal hard disk drive.

Note: Hard drive cameras may not function correctly above 10,000 feet.
13.) Flash Memory card - can have both internal and removable memory.
Sony flash memory camcorders typically feature internal storage ranging from 4GB to 96GB,
with many models offering expansion slots for Memory Stick Pro Duo or SD/SDHC/SDXC cards (up to 64GB or higher).
A 16GB model offers roughly 1–2 hours of high-definition recording, while 32GB models can store up to 11 hours 40 minutes.
Internal Storage Capacities
Low-end/Older Models: 4GB to 8GB (e.g., DCR-SX44, DCR-SX41).
Mid-range Models: 16GB to 32GB (e.g., HDR-CX150, HDR-CX430V).
High-end Models: 64GB to 96GB (e.g., HDR-CX760V).
Recording Times (Internal Flash Memory)
32GB Internal: Up to ~11 hours 40 minutes in HD LP mode, or ~10 hours in high-quality (PS) mode.
16GB Internal: Approx. 1 hour 15 minutes at high-quality (FX) mode to over 5 hours in lower quality.
Expansion
Most Sony flash camcorders include a slot for additional storage, including
Memory Stick PRO Duo and SD/SDHC/SDXC cards, allowing for significantly extended recording times
beyond the internal memory capacity.
Secure Digital Memory cards
SD - 2GB and less
SDHC - 2GB to 32GB
SDXC - 32GB to 2TB
SDUC - 2TB to 128TB
SD memory cards can be used with SD devices, SDHC devices, SDXC devices and SDUC Host Devices.
SDHC memory cards can be used with SDHC devices, SDXC devices and SDUC Host Devices.
SDXC memory cards can be used with SDXC devices and SDUC Host Devices.
SDUC memory cards must only be used with SDUC Host Devices.
SD (Standard Capacity): uses FAT16.
SDHC (High Capacity): uses FAT32.
SDXC (Extended Capacity): uses exFAT.
SDUC (Ultra Capacity): uses exFAT.
Physical Form Factors:
Standard SD, SDXC, and SDUC cards are all the same physical size (roughly 32mm x 24mm x 2.1mm)
and share the same form factor. They are physically interchangeable in devices that support their respective standards,
with the difference being their storage capacity, file system, and speed, not their dimensions.
SD: Standard size, typically used in cameras and laptops.
microSD: Tiny, commonly used in drones, phones, and Nintendo Switch.
Adapters: microSD cards can be used in full-size SD slots with an adapter.
Sony Memory Stick
Introduced in 1998, Sony Memory Stick was a proprietary flash memory card format
used to store data in Sony devices, including cameras. While initially popular, it lost the market war to the
more open SD card standard, leading Sony to adopt SD cards in 2010 while continuing support for Memory Stick.
Key versions included Memory Stick Pro, Duo, and Micro.
1998 (Original): Launched as an ultra-thin storage solution for Sony's digital AV products.
Initial capacities ranged from 4MB up to 128MB.
2003 (PRO and Duo): Memory Stick PRO was introduced, offering larger capacities and speeds,
designed with SanDisk. Memory Stick PRO Duo was introduced, which became the standard for Sony digital cameras.
Late 2000s (Micro - M2): Sony developed the tiny Memory Stick Micro (M2) for mobile phones, often used with a Duo adapter.
2010s ( Decline): Due to the widespread popularity of SD cards, Sony began offering SD card slots on their devices.
Battery life
Your recording time could be limited to the battery
charge (say on a long outing). It does not do any good to be
able to record for 2 hours if your battery is only good
for 1 hour (unless you have extra batteries).
VHS
and VHS-C
VHS
The most
successful of all the home videotape formats has been VHS
(Video Home Service). Although the VHS format
has lasted more than 20 years and spawned hundreds of
thousands of video rental stores around the world,
things quickly started to change with the development
of DVD.
VHS
and VHS-C (or compact which uses the same tape, but in a
smaller cassette) cassettes are compatible with most domestic VCRs
and so can be played in any VHS VCR. This might sound the
ideal format to use because of this fact, but when you
consider that to edit your footage, it must be transferred to
the VCR via a set of connecting A/V leads, the convenience of
being able to put the tape into the VCR becomes somewhat
negligible.
Because
of the large size of VHS cassettes, VHS and VHS-C camcorders
are the biggest. Both formats offer mono soundtracks
with a maximum recording time of one hour in short play and
two hours in long play (VHS-C) or eight hours (VHS).
Unsurprisingly, VHS has become pretty much obsolete as a
format over the last few years and, although a few
manufacturers do still produce VHS-C cameras,
it would seem that this format is following a similar route to
its older brother.
Full-Size VHS: (Video Home
System)
Uses Regular VHS tapes, just like a VHS VCR. One half inch tape
width. The recorded tape can
be played in a regular VHS VCR just like any other VHS tape. Video Resolution is 250 lines just like VHS VCR.
Tape Speeds of 2hrs (SP) and 6hrs (EP/LP) just like VHS VCR. Due to the size of VHS Tape, these camcorders must be shoulder
mounted during shooting. Sound quality is poor, audio is recorded in the same fashion as a
non-HIFI VCR.
Manufacturers: Primarily Hitachi
and RCA
(note: Panasonic has discontinued their line of Full-Size VHS
camcorders for the consumer market).
Compact
VHS (VHS-C)
- Combines the playback
convenience of full-size VHS camcorders with the bonus of more
compact size.
- One tape typically holds
about 40 minutes at SP speed.
- Using an adapter, VHS-C
cassettes can be played in a full-size VHS VCR.
- Records in mono sound.
- Resolution is about 250
lines.
Compact VHS (VHS-C)
Camcorder users who prefer to
insert their video tapes directly into their VCR may want to
consider using the VHS/C compact format. VHS/C is regular VHS video
tape wound into a smaller cartridge.
Since the cartridge is smaller, the
length of VHS/C tape is limited to a maximum of 45 minutes - though
longer times can be achieved using a long play mode, the quality
usually is poor compared to the faster (sp) speed. The compact tapes
are inserted into your VCR using a cassette adapter which comes with
each VHS/C camera. Once inserted, the tape plays just like any other
VHS tape you've ever used.
VHS-C uses a much smaller physical version of the VHS tape but still one half
inch tape width. Although compatible with the VHS tape format,
tapes must be placed into an
adapter in order to be
played back in a home VCR. The Camcorder can also be connected to a
VCR or TV via A/V cables and the tapes can then be copied onto a
regular VHS Tape if desired.
Video resolution is the same as regular VHS VCR, 250 lines. Tape speeds are SP(30min) and EP/SLP(90min). Since the cassette is much smaller than a regular VHS
cassette tape, the amount of tape available
in the cassette is much less, necessitating shorter recording times.
With smaller tapes, these camcorders can be much smaller, thus are
easily handheld, rather than shoulder mounted. The sound quality is the same as a Full Size VHS camcorder or non-HiFi
VCR.
Manufacturers include, Panasonic,
JVC, RCA
SVHS-C
This format is the same as VHS-C except that the resolution is
higher at 400 lines (which is 60% higher than VHS or VHS-C). This
necessitates the tape being played back by the camcorder or in a
S-VHS VCR (using the supplied adapter). These camcorders can both
play and record in standard VHS-C as well. However, a regular VHS-C
camcorder cannot play recorded SVHS-C tapes.
Manufacturers: primarily JVC
VHS
took a step forward in quality when S-VHS
(super VHS) was introduced. Some news operations
started using it as an acquisition
format that could be brought back to the
production facility and immediately dubbed
(copied) to a higher quality format for editing. This
minimized any subsequent loss in quality due to
editing.
To
reduce the size of camcorders a smaller version of the
VHS and S-VHS cassette is also available. VHS-C
and S-VHS-C
("C" for compact) are a fraction of
the size of the standard VHS cassette. They were
designed to compete with the small 8mm format
(discussed below) that found favor with a large number
of consumers.
Using
S-VHS equipment in news has some major advantages;
specifically, the equipment is easier to operate than
professional equipment, it's lighter in weight, and
it's far less expensive.
A quality S-VHS camcorder
costs one tenth as much as professional equipment. This is significant in
covering news in third-world countries where some
regimes have a habit of confiscating reporters' tapes
and equipment in an attempt to censor things they
don't want the rest of the world to know about.
Like all of the
videotape formats, VHS tapes have a record
lockout provision. Once you break off the
small plastic tab, machines will no
longer record on the tape. This makes it
possible to keep important material from being
accidentally erased.
You can restore the record option on a VHS tape
by wrapping a strong piece of tape over the tab
area, or otherwise filling in the hole created
when the original tab was removed. (This is a procedure that works, although not recommended by manufacturers.)
S-VHS
and S-VHS-C
S-VHS
(or Super VHS to give it its proper name) was developed as a
superior format to VHS. Using advanced picture processing
techniques and advances in tape technology, S-VHS offers
considerably better picture quality than VHS and VHS-C but,
along with S-VHS-C suffers from the same fundamental frailties
as VHS, offering the same running times and necessity for
large camcorders. One other drawback is that S-VHS cannot be
played on a VHS VCR, you will need to buy an S-VHS deck to
watch your footage.
Like
VHS-C, S-VHS-C takes the high concept behind S-VHS and shrinks
the format to a more manageable size. Improved recording
capabilities have produced a more highly specified generation
of camcorders. The choice is limited, though and the amount of
S-VHS-C camcorders is becoming less and less every year. S-VHS
is more commonly seen in the S-VHS-ET format these days. The
ET stands for expansion technology and refers to JVC's
technological advance which produces high-quality images
equivalent to S-VHS onto a regular VHS cassette.
Compact VHS (SVHS-C)
- Over 400 lines of
resolution on specially formulated VHS-C tape. (SVHS-C
camcorder can also record with reduced resolution using
standard VHS-C tapes.)
- Using an adapter, SVHS-C
cassettes can be played in a full size SVHS VCR. With a
couple of exceptions, however, SVHS-C recordings cannot be
played back in standard VHS VCRs.
- One tape typically holds
about 40 minutes at SP speed.
- To obtain optimal picture
playback, you should connect the camcorder to the S-video
input on your TV or SVHS VCR.
Super
VHS, a full-size
format with resolution similar to that of HI-8, is virtually out of
the consumer camcorder market. The format still is a strong player
in the industrial market, but its future may be bleak with the
release of newer and better digital formats. This format is used for
videographers mostly for shooting and editing. The S stands for
super, as the resolution jumps from the VHS standard of 250 lines to
around 400 lines. Unfortunately, most VCR's will not play a super
VHS tape and has to be transferred to a regular VHS format in order
for it to be viewed on non-S-VHS machines.
8mm
8mm
uses a completely different tape system than the 0.5 inch VHS
format. As the name suggests 8mm uses tape that is 8mm wide,
making the cassettes (and so the camcorders) smaller and
lighter. Maximum running time is two hours in standard play
and four hours in long play. It is the superior FM audio
system (mono and stereo) that sets 8mm apart.
All
8mm cameras record sound using the hi-fi multiplexing technique
so even if they are equipped with mono sound, there is no
obvious deterioration of audio quality when recording in the
long play mode. Audio dubbing can also be employed on a VHS
copy of 8mm material if you have a suitable VCR with audio dub
mode. Although
this format is still going strong, it looks like
manufacturers may stop making 8mm camcorders in the near
future. Sony for one stopped at the beginning of 2001.
When
Betamax (not to be confused with Betacam) didn't survive, 8mm
video was introduced. The format in part tried to cash
in on the "8mm" designation that had long
been a household name in home movies. In fact, Eastman
Kodak was one of the originators of 8mm video.
The
reduced size of the 8mm cassette meant that camcorders
could be made even smaller than VHS camcorders, a
feature that attracted people who had grown weary of
dragging around their bulky, full-sized VHS camcorders
.
At about
the time that S-VHS was introduced Sony introduced Hi8,
a higher quality version of 8mm. This is also used as
an acquisition format, and under optimum conditions
can produce high quality video.
In
mid-1999, Sony introduced Digital-8
for the consumer market. This format not only
represented a major improvement in quality, but the
digital approach made new camcorder features possible.
8mm
- Hi-fi mono or hi-fi stereo
recording provides improved audio over VHS-C.
- Tapes cannot play back
directly into a VHS VCR, even with an adapter.
- One tape holds up to 2
hours at SP speed.
- Connect the camcorder to a
TV or VCR for playback.
- Connect the camcorder to
your VCR to edit or copy tapes.
- Horizontal resolution is
about 250 lines.
Uses tape that is smaller than that of VHS or VHS-C. Tape width is
about one third inch. Tape can be
played back by connecting the camcorder via A/V cables to a VCR or
TV. Tapes can be transferred (copied) to a regular VHS tape.
Note: An 8mm tape cannot be placed in a regular VHS VCR for
playback, there is no 8mm adapter!
Video resolution is 250 lines, about the same as VHS or VHS-C
(although the color consistency on 8mm is slightly better).
Tape speed is typically 2hrs (SP) although Sony supports a 4hr
(LP) tape speed in their camcorders. Since the tapes are small (about the size of an audio cassette),
8mm camcorders are small units that are easily handheld.
Sound quality is good. Sound is recorded in the same fashion
as on a HiFi VCR.
8MM camcorders
often have many of the best features found in higher priced HI-8
units, including image stabilization, strong optical and digital
zooms and innovative special effects. Regular 8mm tapes are the
exact size and shape as their HI8 counterparts, but record video at
a lower resolution level, and therefore, are less expensive than
camcorders which product better image quality. 8mm can record for up
to 2 hours and has a resolution of 270 lines.
HI-8 and regular 8MM tapes cannot
be put into a standard VHS video recorder, a common misconception.
There are no adapters to achieve this. They must be transferred to
VHS in order to be viewed on a regular VCR.
VHS-C and full
size VHS record at a slightly lower resolution than 8MM. A
standard T-120 VHS tape has a recording time of 2 hrs, and the
resolution is 250 lines. Their appeal, or course, is the convenience
of easy playback. The large VHS camcorders are almost a thing of the
past at this point. There are still a few models available, but
their substantial size and weight make them a difficult sell against
smaller camcorders. VHS/C compact models, on the other hand, remain
a popular choice, offering many of the same key features as 8MM
camcorders, at an equally affordable price.
Manufacturers include; Canon, Sony,
Sharp, Samsung,
and Hitachi
Hi8
Entering
the camcorder market from the same high resolution angle as
Super VHS, the Hi8 format uses the latest in metal evaporated
technology to offer better pictures than 8mm, making it by far
the most impressive analog format available.
The
low weight of both the camcorder and cassettes is important as
is the availability of long playing time. As with 8mm
cassettes, Hi8 tapes cannot be used in VHS VCRs (although
composite leads can be used to link up the camcorder to the
VCR for copying onto a VHS tape). The price of Hi8 machines
has fallen considerably recently, thanks to the ever growing
popularity and drop in prices of DV camcorders, and Hi8 looks
to be a very affordable format. This
trend looks increasingly likely to continue, but exactly how
long the format will stay around is very much in the
manufacturer's hands.
Hi8mm (High-band 8mm)
- It can reproduce images
significantly sharper than standard 8mm and VHS-C
camcorders, about 400 lines of resolution (up to 440
with Sony's XR extended resolution scheme).
- Your TV should have an
S-video input to take advantage of Hi8's improved
resolution.
- Hi8 (evaporated metal
particle) videotape is required to take advantage of Hi8's
higher picture resolution, but all Hi8 camcorders can
record in the lower-quality 8mm format.
- Hi8 is not compatible with
a VHS VCR.
- One tape holds up to 2
hours at SP speed.
This format is the same as 8mm except that the resolution is about
60% higher at 400 lines. Once again, there is no adapter to play
these tapes in a regular VCR, however, all HI-8 camcorders can play
and record in the regular 8mm format. Regular 8mm camcorders cannot
play recorded HI8 tapes.
HI-8 camcorders
record their signal at about 400 lines of resolution, slightly less
than Mini DV, but substantially higher than 8mm or regular VHS
formats. Most often, HI-8 camcorders record sound in hi-fi stereo.
Slight quality loss is suffered when copying or editing from HI-8,
but a better than average image is maintained.
Tapes from HI-8 camcorders
generally must be played using the camera as the source, which means
the user often must connect cables to their television or VCR.
HI-8 tapes can be bought in 30, 60, and 120-minute lengths.
Manufacturers are Canon,
Sony, Sharp,
Samsung, Hitachi.
Digital8
Introduced
by Sony, Digital8 promises the same image and audio quality as
DV, but records the signal directly onto a Hi8 analog
cassette.
Digital8
camcorders feature a dual-speed head which also allows the
camcorder to play back analog recordings made on Hi8 or 8mm
camcorders (making this a perfect option for those that have a
lot of analog footage archived, but also want to get into
digital video). A 90 minute Hi8 cassette will give 60 minutes
of recording in Digital8 (there is no long play mode). Picture
resolution is claimed at around 500 horizontal lines and audio
is recorded in 16-bit PCM stereo (meaning no audio dub).
Because of the larger size of Hi8 cassettes compared to DV
tapes, Digital 8 camcorders are generally bigger than their DV
counterparts.
Digital8 (Sony exclusive format)
- You'll
get studio-quality video with 500 lines
of resolution, 2x the resolution of
8mm and VHS-C.
- Makes
perfect copies from one camcorder to
another with no loss in picture quality.
- Digital8
uses any 8mm or Hi8 videotape, although
Hi8 is recommended, and records up to 1
hour at SP speed.
- Plays
back 8mm and Hi8 tapes recorded in
older, analog camcorders
This camcorder format takes advantage of existing
HI8 format and pushes it into the Digital realm. Uses either 8mm or HI8 tape. As of now the only way to play the
tape back is through the camcorder connected to a VCR or TV or by
Digitally playing the tape back by connecting the Camcorder to a
computer via its IEEE-1394 (Firewire) port (special hardware and
software required, not included with camcorder). These camcorders can also play back previously recorded analog 8mm
and HI8 tapes using the regular A/V connections, but at present
cannot convert the analog 8mm and HI8 recording for direct pass
through to a computer via the IEEE-1394 port. Video resolution approaches 500 lines, which is 20% higher than
HI8 or SVHS-C.
Tape speed of one hour is currently available, when using a 2hr
length HI8 or 8mm tape. Camcorders are the same physical size of 8mm and HI8 camcorders,
thus are easily handheld. Sound quality is excellent. The sound is recorded in either 12bit
or 16bit PCM Audio for almost CD quality sound. The Digital8 format also allows for still frame capture.
DIGITAL8 is
a format that is far superior to HI-8 or 8MM. Sony was the first to
introduce this format. It is backwardly compatible, meaning that the
Digital8 camcorders and VCR's will also play your 8MM and HI-8
tapes. You do not have to buy special tapes to record in Digital8. A
regular 8MM or HI-8 tape will record up to 60 minutes of digital
video and audio. Because of the design, using regular tapes is not a
problem, but it uses twice as much tape. A 2 hour HI-8 or 8MM tape
will record 60 minutes when done in the Digital mode and records up
to 500 lines of resolution.
Manufacturers: Currently only Sony.
MiniDV
Digital
Video, or Mini DV as it is often referred to, delivers the
very best picture quality (as many as 500 lines of horizontal
resolution) and has CD-quality PCM stereo sound with the
ability to perform audio dubbing.
Most
camcorders use mini DV cassettes (about the same size as a box
of matches), which means that DV camcorders are among the
smallest camcorders in the world, shrinking in size as
technology advances.
Footage
can be transferred from DV camcorders in three different ways.
Firstly, as a composite analog signal via the composite A/V
leads (like any other analog camcorder). Secondly, as an
S-video analog signal and lastly as a DV signal. This method
involves the i.Link digital interface often referred to as
Firewire. When transferring footage from the cam to a DV VCR
or PC using this connection, there's no loss of quality of
sound or audio, one of the main reasons why DV is so popular.
All
DV camcorders have i.Link out (or DV out), but if you wish to
use a PC-based edit system then you'll need i.Link in (DV in)
as well.
Mini DV
- These
camcorders are popular with
professionals and serious hobbyists as
well as consumers.
- Most
Mini DV models use superior-quality
optics.
- The
camcorder itself can be quite small,
literally pocket-sized.
- Blank
Mini DV tapes cost more than analog
tapes.
- Records
up to 2 hours at SP speed.
- Resolution
is about 500 lines.
MiniDV
Uses extremely small 6.35mm tapes (one fourth inch, similar is size to DAT
Audio Tapes). Tapes are played back through the camcorder via A/V
connectors to a VCR or TV or to a computer, using the IEEE-1394 port
(extra hardware and software required).
Video resolution is 500 lines, which is 20% better than HI8 or SVHS-C.
There are typically two recording speeds SP and LP, which
allow 60min or 90min recording times.
Since the tape is so small, camcorders of extremely small size can
be manufactured, some are not much larger than a pack of cigarettes.
Sound quality is excellent. Audio can be recorded in either the
12bit or 16bit PCM format, which can produce almost CD quality
results. In the 12bit mode there is provision for in-camera audio
dubbing.
The MiniDV format also provides for still frame capture, with some
camcorders using Progressive Scan technology for more accuracy in
this mode of operation.
The MiniDV technology should take and maintain
crystal clear images because of the nature of a digital format.
Editing enthusiasts benefit from Mini DV as well, since copying
between two units is done with no quality loss. That means edited or
copied video looks and sounds every bit as good as the original
footage. Mini DV tapes are available in 30, 60, 63 and 80 minute
lengths. Digital camcorders have the highest resolution of all
the camcorders, starting at 500 lines.

Manufacturers: Sony,
Canon, Sharp,
JVC, Panasonic,
and Samsung.
DVD
DVD-RAM, DVD-R, DVD-RW
DVD-R has 1.47GB single sided optical disc for 30 min. of recording time.
DVD-RAM has 2.9GB dual sided optical disc for a
total of 60 min. recording time in fine quality mode (2 hrs standard
mode). Up to 2,000 still photos on DVD-RAM. No more tape rewinding
or fast forwarding as you can go directly to each scene. Digital
stereo sound. Cutting edge technology in the year
2000. (DVD-RAM does not
play on all DVD players)
--Manufacturers: Sony,
Hitachi, Panasonic
Hard Disk Drive
Camcorder has built-in hard disk drive for recording. 60GB or 120GB is common. One disadvantage of hard disk is once the disk is full, you cannot record any more video without sacrificing existing video. You must download to a DVD or computer drive or online site. With tape, DVD or flash card based camcorder, you can insert another media and continue recording. Very popular 2008-2009.
Flash Memory Card
Camcorder can have built-in memory for recording and removable memory cards. 4GB, 8GB or 16GB is common. Costs for memory cards are coming down. Small size of cards allows storage of video without taking up space. Can easily download to DVD or online site. High Definition is available but be careful of incompatibilities. Becoming more and more popular 2009.
Summary:
There are a wide
variety of choices in camcorder formats. If you are looking for the
most convenience, VHS-C, with its compactness and ability for its
tapes to be adapted for play in a regular VCR might be your best
choice if you are not looking for the latest technology.
If you travel a lot and length of
recording on each tape is important to you, then 8mm or HI8 may be
good choices. In addition, these camcorders are also compact and are
easily carried.
If you are upgrading from HI8 or
8mm and don't have a way to continue to playback your library of old
HI8 or 8mm tapes, you might be a good candidate for Digital8. This
format provides a means of playing back your older tapes, while
enabling you to enter the world of Digital Video.
Finally, if you need something that
is extremely compact, are into video editing, still photo capture,
have a high-powered computer, or just want the latest and greatest,
then jump to MiniDV.
DVD
camcorders are popular because they are small and many allow you
to play your disc in a DVD player. Scene access is much better
than tape since it is direct. See this
for more details.
Considerations:
There is NO 8mm/VHS adapter! 8mm tapes
cannot, under any circumstances, be played in a VHS VCR.
There are several reasons
that 8mm (or Hi8 and miniDV tapes) cannot be physically played
in a VHS VCR:
1.
8mm (Hi8, miniDV) is a different format with different
technical characteristics than VHS. These formats were never
developed with the intention to be mechanically compatible
with VHS technology.
2.
8mm/Hi8 tapes are 8mm wide (miniDV is 6mm wide), while VHS
tape is 1/2" wide, making it impossible for a VHS video
head to read the taped information correctly.
3.
8mm/Hi8/miniDV tapes are recorded and played at different
speeds than VHS, so even if the tapes could physically fit
into a standard VHS VCR, the VCR still couldn't play back the
tapes at their correct speeds.
4. 8mm/Hi8/miniDV audio is recorded differently than VHS. 8mm/Hi8
audio is recorded in AFM HiFi mode, while miniDV audio is
recording in 12-Bit or 16-Bit PCM digital audio format. So,
even if the video could be played back in a VHS VCR, the audio
could not be read properly.
5.
8mm/Hi8 video is of higher resolution than VHS and is recorded
in a different bandwidth length (miniDV video is recorded
digitally), so once again, a standard VCR still could not read
the information correctly, even if the tape could fit into a
VCR.
The lack of mechanical
compatibility with VHS VCRs is actually the strength of the
aforementioned camcorder formats.
First:
8mm/Hi8/miniDV tape has a longer recording length than the
VHS-C compatible VHS tape: In its standard SP speed, the
longest VHS-C tape is 40min, while miniDV is 1 hour, and
8mm/Hi8 is 2 hrs.
Second:
Not being mechanically compatible with VHS gives the 8mm/Hi/miniDV
formats the ability to achieve higher technical standards in
terms of video resolution and sound quality.
For the
slight inconvenience of having to connect your 8mm/Hi8/miniDV
camcorder to your TV or VCR with cables to watch your video,
you have the advantage of newer technology that outpaces the
abilities of your VCR or a VHS-C camcorder.
However, even though 8mm/Hi8/miniDV
tape is not physically compatible with your VHS VCR, you still
have the ability to transfer and edit your camcorder videos to
VHS or DVD.
To transfer your 8mm/Hi8/miniDV
tape to a VCR, just plug the Audio/Video cables supplied with the camcorder to the AV outputs of the Camcorder
and then to the
AV inputs on either front or back of the VCR, switch the VCR
to AV-in, Line-in, or Aux in (depends on brand), put the tape
to be copied in the Camcorder, put a blank tape in the VCR,
press play on the Camcorder, press record on the VCR and you
will be able to copy your tape. You can transfer your
MiniDV video to DVD if you have a DVD recorder. Using a
IEEE-1394 (4-pin Sony iLink) cable from the camcorder to the
DVD recorder, you can transfer from tape to a standard DVD
Video.
Also, check the owner's manual
of either your Camcorder or VCR; there should be a page on
copying your tapes or copying from one VCR to another (which
is the same procedure). You can also watch your tape at the
same time it is being copied. In addition, if you own a
standalone DVD recorder, you can also copy your tapes to DVD
using the above process as you would with a VCR.
Copying your
camcorder tapes gives you the opportunity to cut out those
boring parts and mistakes. You can send the polished copy to a
friend or relative or just keep it for your own viewing. In
fact, since 8mm/Hi8/miniDV are higher resolution formats than
VHS, you will make better tape copies onto VHS. Every time you
copy a tape you lose quality, the better quality the source
material, the better the copy.
Use this analogy: When you
buy a movie at your local video store and play it on your VCR
it looks much better than if you had taped that same movie off
of TV.
The reason: the source of the tape is a direct copy of
a studio master, whereas that same master broadcast over cable
or the airwaves is degraded from TV transmission artifacts,
then by the time you copy the movie, you not only copy the
movie but any transmission defects along with it. Think of a
tape recorded in 8mm/Hi8/miniDV as similar to a copy from a
studio master and the tape copied from another VHS master as
being copied from lower resolution source material.
Now, if you are still craving
a way to play your 8mm/Hi8/miniDV tapes in some kind of
player, there are solutions, but they are not cheap. There are 8mm/Hi8/miniDV VCRs made by
Sony and Panasonic. In addition, JVC makes miniDV/S-VHS/VHS VCR Combos. See this
for more.
High Definition - Video recorded in HD may use a proprietary method such as AVCHD which is used by Sony. As such certain techniques may prove incompatible when trying to copy video to another media. Often a lower-resolution copy can be transfered that may be more compatible with other devices. Camcorders using AVCHD may prove more compatible if used with other Sony devices such as Sony Blu-ray players or Sony DVD burners. Always check before you buy and think about how you'll transfer video.
Professional Video Formats
The following summarizes the basic formats
for the professional camcorder market.
U-Matic: Also known as
3/4" video tape. The format was introduced in 1971 but it is
still used by some videographers who have been using the format for
a long time. It can produce good quality video and 3/4" decks
are still commonly available in duplicating houses. However, there
is little reason for somebody to pursue this format given the
technical advantages of some of the other more recent formats. U-Matic has been used by professionals the world round and found
mostly in studios. The format is slowly being replaced with digital
equipment such as DV and Mini DV.
BetaCamSP: BetaCam was
first introduced in 1982. It is currently geared for broadcast use,
although there have been some less expensive models destined more
for industrial use. Pictures you will get using a BetaCam system (or
other component format) will generally be markedly superior to those
you would get using any of the preceding formats. Colors in
particular come out looking much more vibrant and objects appear
three-dimensional. The superiority of BetaCam shots comes partly
from the technical aspects of the tape format but also in large part
because of the use of superior optics and other camcorder and VTR
components.
The difference between BetaCam and
BetaCam SP, introduced in 1986, is in the tape. BetaCam SP uses a
metal tape and is an improvement over BetaCam.
BetaCam cassettes are large. Ninety
minute cassettes measures 5.5 by 10 inches (14 by 25 cm). Typically
BetaCam field units (camcorders or dockable decks) handle only
smaller cassettes with shorter lengths of tape (30 minutes and
less). These smaller cassettes are 4 by 6 inches (10 by 16 cm) in
size.
BetaCam SP is still the de facto
standard for professional broadcast videotaping, partly because of
the large number of units out in the professional videotape
community. Some authors assume that over 90% of all professional
videotaping is done using Betacam and Betacam SP. BetaCam
SX introduced in 1996 is a digital format.
MII: Introduced
in 1986, is Panasonic's answer to BetaCam SP. All MII tape is metal.
The 90 minute cassette at 4 by 8 inches (11 by 19 cm) is
considerably smaller than the 90 minute BetaCam SP cassette. However
the dockable decks take only a small 20 minute cassette (3.6 by 5
inches - 9 by 13 cm).
Technically, MII is equal to or
superior to Betacam SP. Panasonic MII field equipment includes
several small dockable decks usable with a variety of camera heads
and some excellent portable decks.
Be aware if you get into MII that
at some point repairs may become an issue and that few duplicating
facilities or clients are likely to have MII. Therefore you will
probably have to copy your MII programs to another format at some
stage.
The quality of videotape formats is usually measured in
lines of "horizontal resolution." Horizontal resolution is a
term measuring the clarity in a single scan line of a
television image. The higher the number, the better the
quality and detail.
However, "horizontal resolution" is a misleading term. The
lines that run horizontally across an NTSC television screen
are set, fixed, at a solid 525 lines. The lines that run
vertically up and down a NTSC screen are relative. But, the
vertical-running lines are creating a pattern across the
horizontal plane of the screen, so they are called "horizontal
lines" even though they run vertically. This makes it very
confusing to explain vertical and horizontal resolution.
The vertical line resolution stays
fixed all the time. The
newest JVC to the oldest Sanyo all had the same 525 lines.
But, the horizontal resolution can increase a great deal as TV
technology improves. Standard analog broadcast television in
the United States has about 330 lines of horizontal
resolution. In comparison, a DVD has about 480 lines of
horizontal resolution.DV, DVCPRO, DVCAM (1996 - 1998)
DV is a format
backed by manufacturers such as
Sony, Philips, Hitachi, Matsushita
(Panasonic) and others.
As the first
digital video recording system for consumers, Mini DV
represents a significant advance in video quality over
conventional analog recording, with an unprecedented 500-line
horizontal resolution-100 lines greater than Hi8 or S-VHS
recording. The DV
format has two cassette sizes: Standard/
Full Size (125mm by 78mm by 14.6mm) and
Mini DV (66mm by 48mm by 12.2mm). The new DV
VCRs will accept both, but the current crop of camcorders
accept only the Mini DV.
DVCPRO
is a professional variant of DV by Panasonic. The only
major difference is doubled tape speed, which is needed for
better drop-out tolerance and general recording robustness. It
is also capable of 4x normal speed playback. This doesn't mean
ordinary Fast Forward with picture, but rather, accelerated
transfer of all of the information, for example, into a
non-linear editing system.
DVCam is Sony's variation of the theme, sitting
somewhere between DV and DVCPRO. Tape speed and track width
have been increased, but not as much as for DVCPRO. Furthermore, it uses the same metal evaporated tape as DV,
while DVCPRO uses metal particle tape.
DVCam DVCAM is the exact same size as
DV and is backwards compatible with DV. The format has the
exact same resolution as DV, however, the "track pitch" is
wider on DVCAM. This means that the tape physically spins
around the spools a bit faster than a DV tape and therefore
the video information is recorded over a longer span of tape.
Being more broadly recorded onto the tape means the image is
less prone to dropouts or loss in quality. To be more
specific, DV uses 10 micron tracks in SP recording mode and
DVCAM uses 15 microns.
DV and DVCAM tapes and VTRs are widely compatible. For
example, it is possible to record professional DVCAM signals
onto consumer DV tape. It is also possible to play back a DV
recording on a professional DVCAM machine. In a pinch, it is
possible to use consumer media in professional DVCAM hardware.
