VHS
The same format used by in a typical home
video recorder- just make your home videos using a VHS camcorder and
normal VHS tapes and play them on your VCR. But this compatibility
comes at the expense of quality. All video resolution is measured in
lines (a bit like pixels in still digital cameras), and VHS has a
maximum of 270 lines - compared with a much sharper 480-500 lines for
digital video. VHS camcorders and tapes also take up a lot of storage
space.
VHS-C
Like normal VHS but smaller. It's small in
recording time, too - you can fit only about 30 minutes of footage on a
tape. It has the same low price, low resolution and 1/2-inch tape width
as normal VHS, but you'll need an adapter to play VHS-C tapes on a
normal VCR.
S-VHS
Super-VHS tapes look the same as standard
VHS tapes but offer 400 lines of resolution and better audio. On the
downside, only a few standard VCRs can play S-VHS tapes. S-VHS
camcorders tend to be big and expensive, and they're mainly targeted at
professionals.
8mm
This tape format offers about the same
resolution as VHS (270 lines), but the tape itself is much smaller and
has a longer recording time of 120 minutes at standard speed. 8mm tapes
won't play in your VCR, but you can connect your camcorder directly to
your television.
Hi8
Hi8 is like an advanced (and more expensive)
version of 8mm, with 400 lines of resolution and all the advantages of
a small, lightweight format.
Digital8
This is the 500-line DV format recorded
onto 8mm or Hi8 tape. It's big advantage (apart from the
budget-friendly price) is the ability to play old 8mm and Hi8 tapes, so
it's a great choice if you want to upgrade from Hi8 or 8mm.
MiniDV
This is the most popular DV format.
MiniDV tapes are smaller than 8mm tapes and can record about an hour of
footage and sound. They have more sophisticated lenses and effects than
Digital8.
DVD
If you have a DVD player you could buy a DVD
camcorder to record directly to DVD-R or DVD-RW discs. DVD camcorders
have similar features to mid-range MiniDV camcorders, but tend to be
bigger and cost a little more.
