    Hi, I want to bring a Flash movie with an alpha channel into AE can anyone tell me what the correct interpretation of the alpha channel should be?
    thanks

    The correct interpretation of ‘any’ alpha, is the ‘type’ of alpha the file has.

    Again, simply try premult and then straight. If neither works, then guess what? You have no alpha in your Flash file and you need to be looking at “How do I output a Flash file with an alpha”,…and not at “How do I interpret a Flash file alpha”.

    In the old days, Flash could not output an alpha,…..so you need to make sure it can do that now.
    BTW – are you bringing in an swf file? OR are you rendering the Flash movie to a sequence of bitmap frames or a Qtime anim? Huge difference.

    I would have the background colour of the flash stage bright blue
    then animate whatever it is your doing..bring it into AE
    and just use the keylight plugin to remove
    the blue..

    good luck

    Marco.

    I’m trying to make a movie in AE and then bring it in to Flash as an swf file but it brings it in with a background?

    Just wondering what i’m doing wrong?
