It is better, but still out by a couple of seconds after 5 minutes. I'm using the following command line; ffmpeg -vcodec mpeg1video -me zero -intra -b 7200 -s 384x288 test1.mpg It only uses around 60% CPU with this command line, and 90% CPU if I omit the '-intra'. Both attempts had sync problems. I'm using mplayer to play the video back... Thanks, Carl.
