so now that i have the final cut library manager, what files can be safely deleted?
optimized, proxy, flow and rendered files. if i delete all of them, can they all be regenerated upon opening the library? I see how the rendered files regenerate when i open, but not sure how the other files work.
They can all be regenerated. For proxies and optimized, select the clips, right-click and choose Transcode Media. Optical flow analysis files are generated whenever you go to a clip in a project that has it applied.
