Hi,
I'm looking to generate uncompressed 4k@480Hz video, preferably a capture from a well-known 'pretty' scene with a good amount of various kinds of movement. Camera pans with foregroud+background, objects crossing each others paths, that sort of thing.
We have been trying to do live capture of vsync'd output from benchmarks, but realtime rendering has it's limitations (as well as the gear we have now).
Alternatively, we can take a very slow moving sequence and play it back faster, but our capture equipment can only do 4k60 and even slow scenes would typically look like a rollercoaster at 8x speed.
Multiple runs with merging frames based on a timestamp is an option, but the timestamp would have to have 1ms or better precision.
Please no discussions along the lines of "You don't need that". I do, it is for research.
10bit color is a plus but not easy at this time.
