I’ve spent several hours Googling and watching how-to videos and reading threads here, on Adobe, on Lynda, and on YouTube, just to find out how to duplicate a nested composition (in my case, a 6-layer title with simple animations) and then make changes without affecting the original. One person claimed that right-clicking the nest in the Premiere project and selecting Duplicate would create a dupe that would not link back to the original, but I have found that to be false.
I don’t want to have to re-create each title composition from scratch for every use of it. I must be missing something, but then, so are all of the videos and threads I’ve studied this afternoon. I can’t be the only person who needs to copy (or duplicate) an edited chunk and then make some changes to it when I use it elsewhere, without affecting the first instance of it.
I’ll report back when I figure this out.
