I recommend a mini-DV camcorder. These record onto small tapes which hold about 1 hour of video. The camcorders can be very small, small enough to fit into a fanny pack, but give excellent quality pictures.
I don't like DVD camcorders for the following reasons:
- In highest quality mode the DVDs only store about 20 minutes of video. This makes your cost per hour of video pretty high.
- In lowest quality mode you can get an hour, but the video is poor (VHS) quality
- Even in highest quality mode, the compression used on DVDs is higher than that of DV tape, so the pictures aren't quite as good, particularly for fast-action.
- The life span of recordable DVDs is not fully understood. It's turning out that some of the DVD-Rs which you can record onto from your computer are dying after just a few years of shelf life, even though the manufacturers tout 100 years! The life span of digital tapes can be measured in decades.
- If you get just one scratch in the wrong place on a DVD, the whole DVD can be trashed - none of the video is recoverable. With a tape, if one spot gets messed up you can cut that part of the tape and splice it, and you've just lost a few seconds of your video.
It's gotten pretty easy to get your video off of a mini-DV camcorder into your computer using firewire and burn it to a DVD if you want to. Or you can use cables to connect the camcorder to your TV.
