    I have read a lot of contradicting info
    about AVI and MPEG4.

    Are MPEG4 files in AVI format (audio-video interleaved with some codec)?
    The MPEG4 spec does not seem to say this?

    I am looking for a document or an article that clears up once and for all what is
    MPEG4 and what is AVI???

    AVI = Audio Video Interleave
    MPEG4 = a type of AVI file, typically associated with DivX and XviD which are both MPEG4-codecs

    The "difference" is that and AVI can have any type of codec (or no codec even) for compression, i.e., CinePak, Indeo, Huffyuv, etc whilst a "MPEG4 'file'" specifically denotes any AVI file that uses an MPEG4 codec (i.e,, DivX)

    Hope that clears thinsg up for ya :)
