It was a simple dream: the ability to record video to a disc, slide it in your DVD player to share, slip it in your PC to edit, and throw it in the mail to friends and relatives. But after several generations of camcorders--and disappointments--we're finally a bit closer to attaining it.

If there's a Holy Grail of technology, it has to be transparency: the seamless, idiotproof ability to do everything you want with the hardware at hand, without having to think about how--it just happens. For camcorders, transparency translates into recordings that you can play, edit, and share without needing to worry about media types, file formats, compression algorithms, hardware compatibility, and other geek esoterica. DVD disc technology initially lured us with its promise of delivering transparent joy. If current products are any indication, some bright spots have appeared in an otherwise disappointing market.
The boulevard of broken dreams
To be fair, some of our gripes with these products stem only partly from suboptimal execution by the manufacturers. For instance, the MPEG-2 compression used by these models seems to need the extra pixels provided by higher-resolution sensors. As a result, the cheap models deliver pretty poor video. All the models have faster bootup time, but you still have to finalize discs to play them in a deck. Finally, optical recording media has one critical flaw in a camcorder: if any data becomes damaged, the entire disc becomes unreadable. Little Johnny's soccer triumph is gone for good.
So for this generation of camcorders, our verdict on DVD changes only a bit: we're past the quality hurdles, but many issues still remain. Those issues will soon include yet another new encoding format backed by Panasonic and Sony, AVCHD, designed to fit HD video onto one of these discs, which will compress the video even more than the current devices.

| Video quality |
Poor to good Generally use proprietary MPEG-2 algorithms, which compress between and within frames. High-end models in the line generally have good quality, but the cheaper models don't. |
Fair to good Uses standard DV format, which compresses only within frames |
| Software compatibility |
Fair The compressed video doesn't survive the editing process very well. |
