alpha export of object with feathered edges, agghhh!
Whenever I attempt to export an alpha channel of an object with feathered edges (or something like text with a drop shadow) out of After effects to be layered over top of video in Avid I get unclean white dots that mark the edges of the object. If I export an object with solid edges (ie. no feathered edges, drop shadows, glows, ect..) everything is clean and good using the export setting of RGB+ Alpha, Millions of Colors, Premultiplied. I have tried for the past several hours testing different export methods from AE and import methods into Avid and nothing gives!!! Any guesses??? Thanks in advance!

Do NOT premultiplied, use Straight color instead.

Export as a .png sequence. Should do the trick.

There are two steps to rendering using straight alphas.
One is the RGB render (which looks like puss on it’s own) and the other is the Alpha render, which you use to ‘cut out’ the colours from the RGB render. Sounds complicated, but it’s not. Check Aharon’s tutorial below.
