Re: New Star Trek Fan Film
Concerning the chroma-keying for the planned sickbay and engineering vignettes don't forget to have a chat with Rob Caves.
I don't know how he did it, but back in the day he had a way to preview a rough composite of live action footage and CG background plates during the shoot. This allows the crew to match the camera angles as closely as possible, eliminating possible problems during the post-production stage. And, Rob being Rob, he has probably refined that advantage a lot more since then.
Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
