This is exactly what I do most of the time, as I said:
“I know there are good habits and best-practices where you always create nested sequences of every element that you send to AE (each ‘nest’ has one track with the source footage and another track with the dynamic link. This can double as an offline-online to speed up rendering and previewing during editing) but this isn’t always done.”
but I’m not the only one who creates projects which I end up editing. There have been many times when someone has given me a timeline full of dynamic links that no longer work, aren’t there or just messed up in some way, and no audio with which to get in/out points from for the source video.
This is what I mean by ‘right click>revert to original footage’ or ‘remove dynamic link.’ What I would like to know is, where about’s is this function or if it doesn’t exist what is quicker than re-editing the sequence and starting from almost scratch.
