Noob here! I captured video of myself writing on my ipad- pure white background with pure black text. I want to import this into Blender 2.8 and overlay it on top of another video, obviously removing the white background. BUT I would like to keep a few pixels of the white so that the text will remain legible even if the new video background becomes dark in places. What is the best way to do that?
The feathering seems to "miss" bits of my text, and the fluffy cloud look isn't really what I want anyway. Really I would like to just keep a few pixels of white running around the edges of all the black. Am I on the wrong track entirely? Thanks!
