I'm working on a short film that's about a half hour long. Out of that half hour, the entire video is composed of basically three source files (one capture file for each of the three days we shot). Every few hours of editing and re-rendering changing effects shots, render files begin to disappear and I'm forced to re-render shots after I never changed them. I'm thinking the the reason behind this is that there's SO MANY render files from one source, "Day 1." Under my theory, Final Cut reaches a certain number of render files per source file and then starts deleting the oldest, assuming that those are no longer in use. Any thoughts? Solutions?
