what command use to convert avi MPEG to MP4 320x240 res, 24 fps?

Do you have any good manual for this (WINFFmpeg is out of way)?

MP4 is a container. There are many different codecs it can use; audio (MP3, AAC, Vorbis...) and video (MPEG4, Theora, H.264, ...) –  grawity Feb 11 '11 at 18:28

ffmpeg -i input.mpeg -r 24 -s 320x240 output.mp4

http://www.ffmpeg.org/ffmpeg.html .. just lookup the terms you used in your question.

What should I install as codec for MP4 for ffmpeg? Because it doesn't support mp4 as I see. –  oneat Feb 11 '11 at 18:32
    
ffmpeg brings its codecs along. win32 builds: ffmpeg.arrozcru.org/builds –  akira Feb 11 '11 at 18:34
    
ffmpeg -formats lists what ffmpeg has builtin/available. –  akira Feb 12 '11 at 10:07

Rather than using a command-line program, someone not familiar with video conversion might try VLC instead. The GUI might make your life a bit easier.
