I am trying to help a student create a graphics package where a strip of film slides into the frame with a video texture showing what's "coming up next". We want to be able to change this video texture in post because the exercise is to mimic a broadcast workflow, as if we create a package and hand it off to a station to use for ID's etc.
Problem is it would be hard to track and attach a solid to because it kinda curves around. Is there any other solution? Any help would be greatly appreciated.
