I did all the instruction in this video,
When I use these nodes in this video,result of the texture out of the outer frame color is white. How can I colorize edges ?
I mean; I want the color effects in the video to appear on the outer edge of the texture out.

In the attached reference screenshot; I want the colors in the video on the left to animate only the edges of the video on the right in the same sequence. I would appreciate if you support me with an example of which nodes I should use.
Best Regards
