Is there currently a feature in AVS to treat a certain color (i.e., white) as transparent in a video in order to make nice looking overlays? For instance, videos must be rectangular/ square in shape, and in order to put a circle in, there would be a white border around it. Is there any way to replace that border with transparency? I know how to edit this externally for images, but only uncompressed video files support transparency. If there is a feature such as the one I have described, could someone please explain how to use it?
By the way, this is my first time posting here, and if this topic is in the wrong area, I apologize.
