Sorry for the generic title but this is a question for people very familiar with FCP. Here's what I want to do: I have ProRes footage that is over 200GB. I was wondering if there is a way to transcode the footage to say, H.264 or something smaller, and edit it in H.264. Next, after I'm done editing it in H.264, can I take the edits applied in that timeline and apply to the ProRes footage? The reason is H.264 would less processor intensive and take up less space I edited it on a portable. READ BEFORE POSTING: Yes, I know I can just get an External HD and move it around, but that's not my point. I just want to know if I footage transcoded into a different Codec, can I apply those edits to the master footage later on. Thanks in advance.
