Thanks for the reply. The commercials reference cut between old news conferences with since retired coaches to actors cracking wise-ass questions. The content is a bit tedious but my point is that the coaches were not shot against a green screen. The ads replace the curtains with team logos and sponsors that were in the original new conferences with Coors Light logos.
That being said, the original source footage was not shot over anything that can be keyed. It was shot over in front of a hospital wall with a computer monitor in the background.
I don’t mind the tedium of separating the speaker from the background if it’s going to look good afterwards. Are the tools here sophisticated enough to do that? I’ll check them out either way. Thanks for the tip!
