Re: PPro / Red / Decklink

Mercury doesn't change where video decode is done...it's CPU-based.

If you have an approved CUDA card installed, you get the push on effects render.

So...with R3D files, most of us would utilize the interface for altering the R3D files as they are decoded...changing the metadata. This would be done in the decode of the frames and therefore would be done in your CPU/Red Rocket pipeline. If nothing else is done than cutting R3D frames and altering the color in the PPro R3D metadata interface (or RED CINE X for example)...it's all handled during the RED decode.

If you added a color correction filter from PPro, say for some secondary correction (and it was an effect that is marked as being CUDA-supported...indicated by the little lego block with the arrow on it), then the CUDA card would pick that work up.

So...I guess the short answer is "it depends". The CUDA cards have a definite impact on the speed of work on the timeline, as long as you're not expecting it to have an impact where it isn't designed to...
