Best Video Playback Codec

I have been using Quartz extensively for playing back loops, adding effects, etc, and I was wondering what the fastest video coedc would be for playback in Quartz Composer?

The clips are usually played at 720, but that may be irrelevant. I have been using video programs, so converting them to any codec is not the problem, but there are so many options I was not sure which would be the most tailored to QC - H.264, ProRes, etc
