I have searched everywhere and cannot find an answer to this. Here's what's happening.
I am keying greenscreen footage in After Effects CS5 and exporting as ProRes4444 with an unmatted alpha channel setting. I can import the clips into Final Cut Pro just fine and layer them together without any problem (which took quite a while to get right).
The problem is that as soon as I move the clip in any way off of its original axis (change scale, center, etc) the clip gets an outline as if it were pre-multiplied with a black matte. It does not make sense to me that moving a clip would add an outline.
I tried to do the same thing in Premiere Pro and had no problems, except that I am much slower in that program, and so is the RT capability on clips of that file size.
I would just edit the whole thing in After Effects, but since it is a music video, I would like to see everything in real-time with audio playing.
I can only notice the outline when I am on a white background, but it really makes it look like rookie greenscreen footage with the outline.
Any help is appreciated.
BTW.. I am on a Macbook Pro Quad i7 2.2ghz running Snow Leo 10.6.8 with Final Cut Studio 3.
You're a genius!!! Thanks for the quick reply. Once I exported to quicktime the outline disappeared. Well the bright side to all of this is I learned how to use Premiere in the meantime, and learned quite a few things about compositing. Thanks again.
