The timeline consist of animated text and images, (background for a green shoot) eventually there will be a talent layed over top of the timeline but as for what you asked there are no keyframes or anything at the point where the video gets cut off. The first 2-3 of the video is just a static screen of text.
The project for now doesn’t have any imported footage or anything, its basically all just pre comps all built within AE. I can get it to fully export on a different desktop at our studio which really doesn’t make sense bc they are all the same setup.
