I have an animation I've exported from Flash Pro CS6 as a MOV file with an alpha channel (ignore stage), and I want to do some editing in AE CS6. When I go to import the MOV as Strait-Unmatted, I do get a transparent background, however when I scrub the playhead with transparency grid toggled, a black background appears behind my animation (see screenshot below). I've tried a number of methods found here and elsewhere on the web including keying out black with luma key, but results were undesirable. Is there a way to get rid of the black behind my animation in AE without effecting the rest of my animation? Or is there an export setting I'm missing in Flash Pro? Thanks!
