I am importing a swf (with a white background) into AE and am getting a dark halo around the edge of the swf. I have tried to change the premultiplication settings in the interpret footage menu, but nothing seems to change. Any ideas on how to remove this dark halo? I am beginning to think animating it in AE is my only recourse.

Thanks in advance.

Is there really a white solid background or is that white background that from the flash 'artboard?' Do you have the flash project with you or did someone give you the .swf?

There is no background, the white is the artboard. It is a character with an alpha around him. I am creating everything so I have the fla file as well.

...and is a white background desired or did you want something with an alpha channel? Personally - I'm not a fan of using .swf files in AE - try exporting a .png sequence instead. Go to File > Export > Export Movie - then set the file type to PNG sequence- select "24 bit with alpha channel" if desired.

Thanks again for your help, Jeff. The animated swf character is being composited over a background in AE so the swf's alpha is desired. That's why I'm surprised there is a black halo around the swf character, it looks as if there is a matte that needs to be smoothed out but I can't figure out how to do that. I would animate it all in AE, but it is so much easier and quicker to import vector elements from AI to Flash rather than AI to AE. AE requires more set up time as it flattens out everything on each layer, while Flash retains all of the layer paths. It just requires more setup, but it looks as though that is what I will need to do if I cannot get rid of the dark halo.

You'll be fine using flash - just export the PNG sequence with alpha - that's what I use to composite all of my Flash Animations.

If you want to try to stick with the SWF file then make sure when you interpret the footage it is set to Straight Alpha rather than Premultiplied.

Hmm..I had it on Straight Alpha to start with, so I'm not sure why I'm still getting the dark matte-like halo. I'll give the png sequence a shot.
