Right, but they should only need to be rendered once. What I’m saying is that I will render out the sequence, save the project, close out of PrP and when I re-open the saved project, those files will be unrendered in the timeline.
Also, sometimes when opening a saved project, the AE animations do come back rendered, but other effects (color correction, transitions, etc.) will not come back rendered.
I can close out and re-open the project again without touching or saving it and the timeline may appear with different portions of the sequence that are unrendered (though they were previously rendered and saved).
