--nvenc-temporal-aq Question #63

Closed TehMaster closed 3 years ago

TehMaster commented 3 years ago

Hey @donmelton (or community),

Quick Q on the --nvenc-temporal-aq flag/setting - Can you really tell the difference between an encode where you used the flag and where you did not? Does this really impact quality enough to where i should get and use a 1660TI instead of my p2000? I can get a 1660 for a very decent price, but want to hear that the quality/difference is worth it.

Obviously the goal is to get the best encodes possible. 👍

Appreciate it as always!

For my eyes, there's a very slight improvement from the stand point of a little less banding and blocking. Back when I was playing with it, I found some scenes that were problematic no matter what and compared them. The improvement was subtle, but observable to me when I was looking for it.

I do my NVENC encoding with a Turing card, so I default to adding the temporal-aq flag. If I didn't, the improvement wouldn't be enough for me to go out and upgrade. Along those same lines, if I had a bunch of non-Turing NEVC encodings, I wouldn't re-encode them just for the temporal-aq improvement. There would need to be some other driver, with temporal-aq just being a nice side benefit.

Hopefully that helps a little. 😎

@ttyS0 Yes, thank you once again! That's an excellent answer!

@TehMaster Is this issue closable now?
