yep can confirm it seems fixed stayed arounf 700 Mb, not tested on a disc as not got any RWs

Good to hear... I wasn't expecting that one to get fixed so fast. I'll test it tomorrow. Sigh... now I need to go back through my code and remove all the changes I made for outputting to .m2ts. It resulted in a lot more changes than I'd expected, and I was still testing it and finding stuff. Two steps forward and one step back.

I can also confirm, that there is a stable RAM usage.

And the best part ... it doesn't seem to matter which turing chip ... i tried with Mike's settings and got around 61 fps on my 1660ti, while the card costs about half
Maybe a Titan would make a difference ... but people could buy a decent car in that price range

BTW: I think with your settings you actually add some height to the video ( pad: [3840x2160]->[3840x2714] (right=0, left=0, top=276, bottom=278) ) ... forgot some dashes?

@jdobbs: why not use the code from 0.61.0.5 and start over?

Dedicated encoding hardware is probably the same

You underestimate how much code it took to integrate it in. I also have implemented a host of other changes since that version. Anyway, I've already reversed most of the code I'd written for it.

Turing NVENC is slower at higher quality settings than Pascal NVENC. The NVIDIA application note for NVENC states that at highest quality you should expect no more than 130fps at 1080p (or around 33fps at 4K).

Extra switches (cmd line options) available
NVenc is on a dedicated chip, same chip across the "line" (family) of cards
https://developer.nvidia.com/video-e...support-matrix
Chip number and number of encoding chips per card

Don't you use Revision Control Software? Programs like Git, CVS and SVN (subversion, which I've managed at a work place) would have allowed you to back out those changes. But, as you've pointed out, a little late now.

I am my revision control software.

I assume, that's because of the B-Frame capability of Turing ... which I don't want to miss, because there is the bitrate saving ...

I'm with you. I want the B-Frame efficiency.

jdobbs do you think you'll add true CPU first pass, then GPU second pass ?? seems the only way to get true 2 pass or maybe add it as an option so people can choose what they want,

maybe get some comparisons of CPU first pass and the lookahead feature to see if theres any quality difference
