    Hi I'm trying to get a mpeg4 with low quality so I'm only changing the bitrate of the video but I don't know how the video that ffmpeg creates has no audio.Any idea?

    So you're not going to tell us what's in the original clip?

    hahaha ok here we go!
    Original:
    mpeg4 (.mov) 320x240
    aac stereo 48,000 kHz
    fps 23.98

    And I want a bitrate around 256 and with sound if it's possible :P

    Apple store aac audio in mov in some odd ways. Don't think that libavformat's quicktime parser can handle it. Remux to mp4 using mp4box/yamb, then ffmpeg should handle the audio just fine. Be much better for everyone (exept for apple) if Apple just used mp4 for MPEG-4 instead of mov.
