analog video to DVD

I converted analog video to digital then captured and burned to DVD. The video is fine in the computer, but the DVD is poor when ever there is camera movement or subject movement.

RL,

"the DVD is poor when ever there is camera movement or subject movement."

Movement stresses the MPEG-2 encoding that is required for DVDs. It takes extra good MPEG-2 encoding to handle any rapid changes in the picture. What bitrate did you use in the MPEG encoder, was it constant or variable bitrate, and which encoder did you use?

FWIW, one of the MS video presentations on winmedia pointed out that the encoder (which works similar to mpeg2 encoders) can go crazy trying to estimate motion etc. with 24 fps footage telecined to 29.97. The way it was desribed is that the encoder hits the inserted frames, sees a slowdown, then hits on one of the original frames and sees it as a speedup. Might try an IVT on your source footage &/or changing the motion estimation values and see if it makes a difference. I've also seen this more then a little after using any temporal type filters on the source footage.
