Re: [Avid-L2] Re: Dilate fill

Thanks Bruce. Can we get that into the help file? Now if we can just keep graphics people from comping a white glow over a black background in AE.

>> What is it? New to me and no mention of it in the help file.

This option was added in one of the v3.0 patch releases.
It bleeds the fill just a bit along the edges where
transparent alpha meets non-transparent alpha.
This is to prepare it for the subsampling conversion to YUV 4:2:2
for compression and the subsequent conversion back to 4:4:4 for keying.
It's mostly intended for importing graphics files containing alpha
that have abrupt transitions between transparent and opaque.
It can help prevent black/gray pixels from seeping into the fill.
Anything that contains softened or anti-aliased edges
(ie: Title Tool images) will not need this option,
since the transitions between transparent and opaque is
spread over several pixels.
