Glossary
 A
camcorder is a great way to document the important and fun events in
your life. Besides wedding and party videos, you can create your own
quirky films, make documentaries of family, friends, and places, and
share your videos with others. Today's camcorders are a thousand
times removed from the big, clunky VHS machines of a decade ago.
Modern camcorders are slim, compact machines with powerful zoom,
image stabilisation, special effects and bright view screens. You'll
find most camcorders to be extraordinarily portable and easy to use.
Choosing a camcorder can be confusing, especially with the
proliferation of multiple recording formats. The days of the VHS
monopoly are long gone: now you can choose between VHS-C, 8 mm, Hi8,
and even digital formats. Camcorders also come with a wide array of
options and features.
Five Quick Shopping Tips
1) Questions to ask yourself: what are you going to be doing
with your camcorder? Your answer to this question will dictate how
much money you can spend and what level of quality you will need.
Some important questions to consider before you run through the
details of our buying guide:
- Who is your primary audience? Family and friends, or will you
also use your video for professional purposes?
- What are your video and audio quality needs? Do you need
pro-level output or just base-line quality?
- Are you interested in video editing?
- Do you need to take digital stills?
- Are you going to make a lot of copies?
2) Format affects quality: the format your camcorder uses
dictates image quality and the kind of tape you'll need. Unlike
digital formats, all non-digital will lose quality as each
generational copy is made. Also, the quality of video and audio
varies according to format. 8 mm, VHS and VHS-C offer the lowest
video resolution. Hi8 and SVHS-C give you improved resolution and
sound, while the digital video (DV, Digital8, or Mini DV) formats
offer the highest level of video and audio quality.
3) Zoom: zoom can be a little misleading in camcorder
statistics. Most camcorders have an optical zoom that ranges from
10x-20x and digital zooms in that same range, resulting in total
zooms of 300x-400x. You probably won't find yourself using digital
zooms too much--they can have dramatic negative effects on picture
quality--so the optical zoom rating is the one you should consider
most important.
4) Image stabilisation: if image stabilisation is
important to you, then look for a camera with optical image
stabilisation--digital stabilisation can decrease image quality.
5) Digital still capability: many camcorders now offer the
ability to capture digital stills. Manufacturers' claims here can be
confusing. Some allow you only to store the images on the tape
itself, which means you have to use a special program to capture the
image. Camcorders with better digital still features use a flash
memory card slot like a digital camera, making it much easier to
store, find and download pictures. Keep in mind that most camcorders
offer only low-resolution 640 x 480 stills--good enough to e-mail or
post on the Web, but not suitable for quality prints.
How Camcorders
Work
Like digital cameras, all camcorders use a CCD, or charged-coupled
device. The CCD is an image sensor that converts the light coming
through the lens into a digital signal. The signal is then converted
to the format the camcorder uses, and then the image and sound data
are recorded onto the tape in the machine. Image and sound quality
depend on the format you use, which is explored next.
Formats
When you're choosing a camcorder, the most important decision will
be which format you want. Camcorders don't all use the same
recording media, and which format you choose will affect everything
you do with your footage--from playback to copies, and even whether
you can employ sophisticated video-editing techniques. To better
understand how camcorders work, it's helpful to think of the
recording format and the actual recording medium (type of tape) as
distinct items.
VHS & VHS-C
The VHS format: VHS is the same format your home VCR uses.
While VHS is a supercompatible format--who doesn't have a VCR these
days?--it has some disadvantages when it comes to quality. Video
resolution is measured in lines, and the VHS format features a
maximum of 270. For comparison, DVD offers 480 lines of resolution.
VHS should be avoided if you're interested in doing semiprofessional
work or any video editing.
VHS & VHS-C tapes: VHS and VHS-C are cheap and easy to
find--and, most importantly, you can play back both types of tapes
in any modern VCR (VHS-C uses a VHS-tape-size adapter that's
included with most VHS-C camcorders). This is an important
consideration if you want to make first-generation tapes for others
or you want to take your tapes to other people's houses without
lugging the camcorder with you. VHS-C does have one drawback that
VHS avoids: the smaller tape size means you can fit only about 30
minutes of footage per tape.
SVHS
Super VHS, or SVHS, is a higher-quality version of VHS that offers
400-line resolution and better audio. SVHS tapes are the same size
as normal VHS tapes, and you can use normal VHS tapes in SVHS
camcorders (but without the quality advantages). SVHS camcorders are
mainly targeted towards professionals; they tend to be pricey and
large.
8 mm
The 8 mm format offers about the same quality as VHS--240 to 270
lines--but the tape itself is noticeably smaller and has a longer
recording time. 8 mm tapes won't play in your VCR, and there aren't
any adapters that allow it, so you'll have to hook your camcorder
directly to your television.
Hi8
Hi8 is a higher-quality version of 8mm (much like SVHS is a better
version of VHS) and offers 400 lines of resolution. The Hi8 format
offers some of the best quality you can get without going digital,
and it's small and lightweight. It is more expensive than VHS or
normal 8mm in terms of camcorders and tapes, but you'll see and hear
the difference.
Digital Video
The digital revolution has finally reached the camcorder market, and
consumers can benefit from the wide selection of digital camcorders
that are now available. The digital video, or DV, format has a host
of advantages. For starters, video quality is very high, at 500
lines of resolution. Colour richness and accuracy are much improved
because digital records across a wide colour spectrum. DV also
records in 16-bit CD-quality audio, and most digital camcorders let
you record 12-bit audio in two channels for layered soundtracks.
One of the biggest advantages to DV is that it lets you make
digital copies without loss of quality, unlike any of the other
formats. While you will experience a loss of quality if you copy to
a VHS or 8 mm tape, it will be comparatively small because the
original image is so high in quality. Most digital camcorders also
allow you to take digital still shots as well, essentially giving
you a digital camera as a bonus.
The big promise of digital video is the ease of transferring
footage to a computer for editing. While the transfer is not as
pain-free as transferring stills from a digital camera, it can still
be accomplished with relative ease. To accomplish the task, you need
a couple things besides your camcorder and computer. First, you'll
need to make sure you have an IEEE 1394 port on your computer. IEEE
1394, also known as FireWire and i.Link, has become the de facto
standard in the realm of digital video. All Apple Macintosh
computers come with this port built in as of this writing (February
2001), and many other manufacturers are following suit. If your
computer doesn't include this port (most PCs don't), you can buy an
expansion card. Be aware that digital video takes huge amounts of
storage space--about 210 MB per minute. That's why digital
camcorders still use tapes (more storage space) rather than memory
chips or cards.
Mini DV: The media most often associated with the DV
format is the Mini DV tape. Smaller than 8 mm tapes, Mini DV tapes
record about an hour of footage and sound.
Digital8: This is essentially the DV format recorded onto
8 mm or Hi8 tapes, while retaining the ability to play old 8 mm and
Hi8 footage. Digital8 camcorders tend to be a bit bigger and heavier
than Mini DV camcorders, but they use the same IEEE 1394 connector
to transfer footage to a computer.
MicroMV: Sony takes "ultra-compact" to the extreme with
the MICROMV series of camcorders, a family of digital video
recorders that incorporate exceptionally compact and well
thought-out design with incredible picture quality, powerful
features and ease of use. The world's smallest and lightest
camcorders makes it that much easier and more convenient to be ready
to capture the moment when something worth remembering happens. They
record digitally on PC-friendly MPEG2 format.
Viewfinder
The viewfinder is probably the most important feature for the
user--it shows you what you're recording. All viewfinders should
show you exactly what you're shooting. Most will even show various
special effects if you're using them. Most eyepiece viewfinders are
actually EVFs, or electronic viewfinders--essentially a tiny LCD
screen. Lower-end camcorders generally come with a black-and-white
viewfinder, which is a great way to cut down on costs, but it can be
detrimental if you really need to pay attention to colours. As you
progress up the scale, all camcorders start to offer colour
viewfinders, and most also have built-in LCD screens that range in
size from 2 to 4 inches. These LCD screens are great for relieving
eyestrain that can occur when squinting into a regular viewfinder.
Some camcorder manufacturers offer devices with only an external LCD
monitor.
Zoom
Most camcorders offer zoom capability, which lets you move in closer
to a subject or magnify an area. Zoom is great for sporting events,
weddings, filming nature and other situations where you're far away
from your subject. Camcorders use two technologies for zoom. An
optical zoom works just like a regular camera's zoom by physically
increasing the length of the lens, essentially creating a magnifying
glass. Optical zoom lets you retain high image quality, but you
usually won't find it at a higher power than about 24x. Many
camcorders also have a digital zoom, which takes a portion of the
image and enlarges it digitally. The downside to digital zooms is
that they can extrapolate only from existing image data, so the more
you zoom in, the more you notice the individual pixels. It's like
when you keep zooming into a picture on your computer--eventually
you can't tell what's what because the screen is a collection of
blocky colours.
Power Source
Many camcorders run on a rechargeable ni-cad battery, although most
of the high-end models have converted to the more advanced
lithium-ion. Both usually last one to two hours. Camcorder kits
usually include a recharger (which often acts as the AC adapter as
well), or the camcorder itself can recharge the batteries. Some
models even have car adapters you can purchase separately.
VCR Capability
For all but VHS and VHS-C camcorders, playback capability is
essential because you'd need a special kind of separate player to
play back 8 mm and digital video. Fortunately, all consumer
camcorders also function as VCRs for their own format, so you can
hook them up to a TV and play back your tapes. Most camcorders
include the basic VCR functions (fast-forward, rewind); many of them
have added search features and come with compact remote controls
(also useful for remote recording).
Light
While most camcorders do a good job of recording in low-light
conditions (inside a house, overcast days), you will encounter
situations where the available light isn't enough to get a good
image. Many camcorders come with a light built in for these
situations--most often, the light can be set to automatically come
on when the natural lighting is too low. Some camcorders also have
connections for snap-on external lights.
Image
Stabilisation
Many camcorders have a handy feature called image stabilisation that
helps correct for camera shake. Recording while walking, using a
powerful zoom or recording a fast-moving subject can lead to shaky
images that make viewers dizzy. Image stabilisation detects camera
shake and helps steady the image. There are two types of image
stabilisation: digital or optical. Digital image stabilisation crops
the image that the CCD picks up and uses the edge for a buffer zone.
While it works well, digital image stabilisation can degrade image
quality slightly. Optical image stabilisation uses a set of lenses
to adjust for unwanted motion; usually only high-end or professional
camcorders use optical image stabilisation because it is expensive
and can add to the bulk and weight.
Microphone
All camcorders should have a built-in microphone, which is often
recessed to decrease wind noise. These built-in microphones are
usually adequate for home recording needs, but don't expect your
home video to sound like a Hollywood film. In films, the actors are
miked directly to cut down on room noises, which camcorder
microphones will easily pick up. Many camcorders also provide
connection capability for a separate external microphone.
Exposure Modes
Camcorders usually sense the correct exposure during the recording;
some also have special settings you can use in certain situations.
These can include backlight compensation (for dark subjects against
bright backgrounds), fast shutter speed (for sports or other
fast-action events) and other exposure modes that compensate for
glare, low lighting, spot lighting, dusk and night lighting. Many
also include the option to manually adjust the exposure and focus.
Special Effects
Many camcorders now offer special effects that could once be done
only by a professional with expensive editing equipment. Some let
you fade out at the end of a scene (and fade back in at the
beginning). Some give you a whole range of fade options, including
fade to black, white or another colour choice; wipe the screen;
close and open on the screen like a shutter; fade to a blurred
mosaic and more. Some camcorders let you record in special video
modes, including effects such as sepia, black and white, negative
and solarised (an effect that makes everything look a bit like an
oil painting). Some also let you shoot in strobe mode for an
artistic-looking slow-motion image. Special effects can be a lot of
fun. Although they probably won't comprise the bulk of your
shooting, they're useful in many situations.
Still Image
Capability
Many camcorders now offer the ability to take still images on the
same tape as the video. Some let you record audio with the image.
These "photos" remain on the tape and can't be printed like real
photos, but they're still fun. All digital camcorders function as
digital cameras as well, letting you take a large number of still
shots on the tape. These still shots can be downloaded, edited and
printed from a PC. A few analog camcorders have added a digital
camera feature: they use a separate memory card to hold digital
pictures, making it easy for you to download and edit them. It's
easy for manufacturers to add this capability since the guts of a
camcorder are remarkably similar to those of digital cameras, so
look for more and more models to gain this functionality in the
future.
Motion or Audio
Sensing
A few camcorders also offer security recording. They use a motion or
audio detector to trigger recording.
