These are all great thoughts, thanks.
I particularly like the idea of running a test and seeing the difference. I think I’ll try a side-by-side comparison. As someone mentioned above, it may be that my intended audience can’t even detect the difference, and it sure is faster to just pull in the fully rendered old videos.
Going forward I should probably find a way to just “set aside” the very best clips in a given project right after I finish with it, so that they are easy to find later. I am still sort of new to this as a hobby and haven’t really perfected my workflow.
Thanks for the advice.
