How can I add glow to a video/media mat?

I am relatively new to programming and using emissive parameters. I have been fidgeting around with the tron glow as taught in unreal articles and tron tuts ; however, i haven’t found one that is specific to a moving image texture. I have a properly functioning .mp4 media file, texture, and mat. but i cannot resolve how to make the whites emissive and the blacks solid.

any wise words?
