I have a client that wants to show off their new 4K video wall with some new content. I've been doing some tests with some of my older footage, and I can spit out a ProRes HQ file no problems. Looks great, plays great. But they want to see an h.264 file, and no matter what I try (through QT, Compressor, FCP, etc.) it always fails immediately.
Does H.264 not support 4096x2304?
Or, what am I doing wrong here?
The footage is from the RED ONE, btw. Though the stuff I'll be shooting will be Scarlet.
