There may be better ways of doing it now, but this sort of thing is why I started working on a dpsReality system. You can render frames to its drive and it automatically sees them as a video clip, so there’s no rendering. It’s got genlock input and key channel output. We render sports animations as TGA32 frames to the video drive, throw the unit into our truck, and have keyable animations to play during our live sports telecasts. Since the dpsReality has been around a long time, they’re relatively cheap too. I have one at home as well.
