Allows various tasks that encode video to use hardware accelerated video codecs.
Basically reuses the existing hardware acceleration pipeline for generation tasks.
On heavy tasks like 8K 41min with 15 markers my generation time goes from 8m to 5m.
On lighter tasks like 1080p 9min its unchanged.
On ultra light tasks like 720p its half speed (which isnt really a long time anyway).
This is from my local testing with NVENC.
Note that it may be wise to reduce the number of concurrent tasks if you have limited
vram.
