Re: Quality issues with logo overlay

Your best bet is to use black as your BG, even if giving it an alpha channel. And you should be rendering your animation straight - not premultiplied. See this video:

http://library.creativecow.net/articles/rabinowitz_aharon/straight_vs_premu...

But even so, if you rendered premultiplied (and clearly from your description, you did) try using effect > Channel > Remove color matting and setting the color to the EXACT color you used as a BG (in your case, the red you're using). That may remove much or all of the crud.

This is in an upcoming tutorial, BTW.

Best,

Aharon
