Hello,
I’ve have an additional problem when exporting an AE comp in uncompressed (millions of colors+) avi format. I always get a white outline around my images. This happens even if I import a sequence of png’s or tiff’s with transparent backgrounds. I can export the same image sequences from Photoshop in an uncompressed avi format with excellent results including the background transparency. I also have
this problem when I use Keylight on green screen footage. I noticed that Photoshop gives you Alpha channel options at export and AE doesn’t. I’m concerned that I may simply have some variable set incorrectly.
Thanks for your help
Keith
