Hey Guys,

I am having what i believe to be a simple issue, i dont think that this is a hard fix, but anyways, how can i get rid of the white line that outlines the logo?

Its brought into after effects and the alpha mode is straight unmatted.

any suggestions ideas?

Change the alpha mode and/or the color it is masked with to white

what do you mean the color that its masked with?

what do you mean the color that its masked with?The color which is used for premultiplication/unpremultiplication.
If you would have tried to change the alpha mode for the footage you would have seen what I'm refering to.

Looks like your 3d guy rendered it on white. Scold your 3d guys, 3d must be rendered on a black background outside where the black part of the alpha is.

oh, I just reread your original post. You should change the alpha to premultiplied alpha unless there was a specific reason for using "straight unmatted"?
