    If a video is 720x480x32, what does the 32 refer to?

    Post a screenshot of it from gspot or avicodec. That way others can analyze it better.
    Donatello - The Shredder? Michelangelo - Maybe all that hardware is for making coleslaw?

    32 is the bit depth

    RGBA , 8 for each channel (red, green , blue, alpha)

    there is no alpha channel in a convential digital still camera , the jpg images would be RGB24 (8,8,8)


    alpha channel is used for transparency. All NLE's work in RGBA to allow for compositing

    you can read up the basics on alpha channel on wikipedia
