NVENC Motion Estimation / Optical Flow Mode

Post by ArthurBonds »

Hi,

I was looking through the documentation for NVENC and found that it can be used as an accelerator for Motion Search and generating motion vectors. While I'm fairly certain it already uses this when Handbrake is in NVENC mode along with actual hardware encoding, is it also possible to have it just generate motion vector hints for a CPU encoding pass to save time? If it is possible, is it even worth it in terms of encoding time or quality to implement?

No. You're welcome to write a patch and try.
