I have a Celeron 600 and the above ffmpeg parms give me excellent video with only the occasional jerkyness, however the audio goes out of sync *very* quickly. After 120 seconds of recording the sound is obviously wrong. How do you keep the audio in sync? Mencoder keeps the audio in sync, but I can only get, at best, 19fps. Any hints? Thanks! Carl.
