Hi, I am using mencoder to covert my video to x264/mp3 format, but just noticed that the converted avi file's audio stream is about 10% shorter than the video stream: Video stream: 196.012 kbit/s (24501 B/s) size: 656639 bytes 26.800 secs 405 frames Audio stream: 46.635 kbit/s (5829 B/s) size: 140184 bytes 24.048 secs The command that I used is: mencoder -noskip -of avi -oac mp3lame -lameopts abr:br=48:vol=2.2 -ovc x264 -vf harddup -srate 8000 -o imgp2161-.avi imgp2161.avi Here is its full log: MPlayer SVN-r29809 (C) 2000-2009 MPlayer Team success: format: 0 data: 0x0 - 0x29d8f3e AVI file format detected.

Any way I can troubleshoot this? Thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/techdocs/ http://xpt.sourceforge.net/tools/
