First,
the Analog model (there is only ONE)
VHS-C (the "C" standing for
compact) camcorders have the lowest picture quality. Horizontal resolution
is at 250 Lines, on the best of days. These units use a compact cassette
that uses a special 'adapter', that allows you to play these tapes in
any VHS VCR, which makes it very convenient for those that can't learn new tricks.
SVHS-C ("S" standing for Super) camcorders are essentially a VHS-C
camcorder on steroids, and have a higher picture quality- almost double the resolution.
Horizontal resolution for SVHS is 400
lines.
There is currently only one model of SVHS-C camcorder on the market today. It's made by JVC, who invented the VHS format - go figure. This camcorder can record both regular VHS, and SVHS. However, the two are not compatible with each other, and SVHS is not compatible with older VCR's..
Hi-8 and Digital-8 camcorders are no longer manufactured. You'll have to buy used if your looking to convert your 8mm, or Hi-8 tapes to DVD. Stay away from all camcorder brands manufactured prior to 1998.
Next,
the digital models:
Mini-DV - The standard of the day, and the choice of many a professional. It's 500 lines of horizontal resolution puts it on even par with broadcast quality. The tapes are small and convenient, as are the camcorders themselves. The picture quality and clarity is governed only by the front end, the lens and the CCD imager.
Mini-DVD- DVD models are digital, and do have
a good picture. However, you should know that these units use MPEG video
compression, and as such do not have as good a picture as Mini-DV, which use JPEG video compression. It's extremely important when handling disks, that you don't touch the surface of the disk, or leave behind any dirt, dust or fingerprints. The ability to record to disk, and then place it in your DVD player, makes it a perfect choice for many families.
DVCAM - This format is used mainly by professionals, but is available to the mass market. The heads have a larger gap, which give the camcorder the ability to be more forgiving, and make it the choice to use when mixing brands of camcorders and decks together. Generally, the DVCAM camcorders are more robust, and have a better front end, which results in better picture quality.
HDD, Hard Disk Drive - Tapeless, at last! But there are trade-offs. These camcorders use the MPEG format, and for that reason, they have less picture quality than Mini-DV, or DVCAM. Also, you have to handle them with kid gloves, as you can damage the hard disk with too much rough handling. A good choice if you want to go tapeless. Quality is even par with DVD camcorders.
Flash Memory - Before recent developments in Flash Memory, these were the cheapest of camcorders, with quality to match. But now, with faster and larger capacity memory, they are now on even par with Hard Drive and DVD camcorders. The consumer models all use MPEG compression, which makes for a very good quality shots, but Mini-DV, or DVCAM they'll never be.
