Looking for general advice on a chromakey workfow. I'm always debating whether I should set up my timeline of just keyed footage and then export it as an Animation and then start a new sequence and add BG material to that, or simply to insert the BG in the original sequence. I "unrender" before exporting. Any suggestions, pros, cons would be appreciated. I shoot in DVCProHD and key with Primatte PRO. I dont have any peripheral hardware for my quadcore.
