What is the lowest rate of encoding MPEG-2 video where the degradation of quality is not noticable by the human eye? The video is fairly low motion (guitar instructional video)
Thanks,
Mike

How big a framesize? What are you viewing it on, how big a TV screen?
352x240 encoded half D1 (352x480) on a 19" TV, probably around 2k.Cheers, Jim

Quality is a subjective thing and also depends on the amount of noise present in the source, the amount of action, and the intensity of panning. Those three things really eat up the bitrate. You state that there's not that much action. Is there a lot of panning or zooming in and out?
The action and panning are intuitive, but the noise is a big reason because the noisier your source, the more information your encoder is trying to digitize. This is especially true when transferring from tape. It'll try to faithfully reproduce everything, even noise. Nuff said about that.
Another factor is the length of recording. The shorter the video, the more flexibility you have in bitrate. If you absolutely, positively have to fit it on one DVD, then you will have to start compromising quality when your video duration passes 2 hours. I'm assuming you will be capturing full DVD resolution of 720 x 480 (or 576 PAL).
