I have two videos, one is fullframe background, and the second is a pip in the top left corner. I would like the second to have a specific shape. I have drawn the shape in a vector application, and rendered a black and white png. I have found how I can cut it using the matte key, but what I would like is the second video to have a 2-4px white border around the cut out shape. As an example: let's say the matte is a triangle shape, I would like the second video to be a triangle in the top left corner with a 4px white border (so, also shaped like a triangle). I have tried several things already. Ideally, because it is for being used in episodical content, I would like it to be an effect that I can drag and drop from a bin. Is this possible, or does anybody have an idea on how to accomplish this? I'm specifically having trouble getting the white border around the video. I'm using Media Composer 8.6.1, and do not have the Boris FX or any other ones. Thank you for your suggestions!
