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 .. 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: – akira Feb 11 '11 at 18:34
ffmpeg -formats lists what ffmpeg has builtin/available. – akira Feb 12 '11 at 10:07
the default codec for mp4 container should be h.264 – Sun May 27 at 18:47

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.

HandBrake is the free GUI alternative to ffmpeg. – Sun May 27 at 18:48
