Transparent Footage - After Effects I have a stock video that is transparent but when I import the footage into after effects it has a greyish/blue background (even when toggling transparency on). Is there something I need to specifically do to get it to be transparent?
It's a .mov file.
I think what you're looking for is to toggle the transparency grid. 

You can do this by finding the checkerboard-looking icon in the toolbar below the viewer.
