Simply put, what comes out of your VCR is not digital, and the quality/syncing depends a lot on the accuracy (cleanness) of the mag reader head. This indirectly causes a mencoder feature/bug that when you end the capture, the indexing of the frames causes the a/v to be somehow out of sync. Therefore, DON'T end the mencoder capture before re-indexing what you have captured. Do something like this: mencoder -tv "<options>" -o outfn-raw.avi ^Z when you have captured enough mencoder outfn-raw.avi -forceidx -o outfn-idx.avi then you can kill the stopped mencoder process. Yeah, I guess capturing to mjpeg should be fine. Then, I'd need to cut the > video. > > What format would be best for cutting (with avidemux?) > Avidemux understands most formats. You can use it to re-encode the outfn-idx file to whatever format you need/want - it has a nice gui front end to most of the mencoder options available. Just remember to add the video filter to drop damaged frames. I typically capture via hardware mjpeg (my card does the compression), and encode via lavc to mpeg4. After re-indexing, I run the video through mencoder for finer processing, using a two or more pass encoding. Hope that helps some. Good luck. ken
