X265 2PASS SLOW quality WAS achieved by NVENC HEVC (Staxrip)

For the human eyes the grain does not exist in real world
Grain represents only the technical limitation of cameras and camcorders.

Nonsense. Grain is not contained to film, and the term existed before its invention. Grain is on fabrics, on wood, on metal. Grain is the texture and surface. In fact, human eyesight is somewhat blotchy when it comes to the color data, and is not 100% smooth, meaning it inherently has some grain.

Clever sharpening

There's nothing clever about the harsh sharpening that you've done, and resulted in unnatural halos. That's just a basic/generic "sharpen" filter cranked up to 11. It's not actually nuanced, and does not take bad side effects into consideration in its algorithm.

I know it from experience from post sharpening of video camera records

What does "post sharpening of video camera records" mean? That's a nonsense phase.

long before you started to notice the simple existence of digital videos.

That's humorous. I started in the 90s, when it was still was not feasible at home. I was using SGI MediaBase for MPEG and LAN streaming. Trying to do anything digital was painful in those days, and I had to wait about 5 more years before digital was actually doable outside of a broadcast/studio/IT facility. I had to suffice with analog setups bolstered by digital techniques.

You've entered the site making asinine claims, and attacking respected when your claims are shown to be BS.

The last time I tested NVEnc it was v3.27 and sadly H265 encoding was completely unusable.
The image quality in black/darker areas was so poor with blocky graphical glitches everywhere.

I'm happy to report things have much improved with NVEnc v4.09 regarding H265 encoding.
The overall image quality looks a little softer and less sharp compared to a H265 software encode. (I've not played around with VPP filters yet).
But the black/darker area image quality has been fixed and now looks much better.

It's far from perfect, but the results are now what I call 'acceptable'.

Encoded 1h36m58s 1080p/24 in 12 minutes @ 200fps.

I tried these filters and it looked atrocious. But with Staxrip I managed to beat the Quality from Handbrake so that it now beats x265 medium as the background has no compression artifacts. Test video was from a 4:3 PAL DVD.

it was done with the Turing Encoder on a 1660 Super

to those that have tried this and believe the results are decent or better.

how far have you been able to push the compression?

i tried for ~39% but it actually ended up being ~57% of my original files bitrate and it seemed pretty good. now that was a stand up comedy thing so wasn't a great test for fast action for example.

it was 720p 3.5Mb/s AVC.

next ill try to do something 1080p with some action. but i suspect ill have to bump it up to at least ~50 to 60%(attempted size), which i would be okay with.

wouldn't mind hearing other peoples thoughts on those that are making use of this.

thanks, and thanks to Comparison for the original post.

Some new profiles for Nvenc 5.24???

Good morning
I read the beginning of this old thread, I ask if currently the X265 coding (via software) is still higher than NVENC (via hardware).
I have the temptation to use NVIDIA hardware speed using high-end video cards, but if the quality is less than x265, I can buy a less performing video card and save money.
Thanks for the answers

The general restrictions of GPU video encoding chips, compared to an all-purpose CPU with gigabytes of RAM, did not change. It is easier to speed up x265 with more RAM and a CPU with more cores and more efficient AVX instructions than enhancing a GPU hardware video encoding chip. And if you tried to copy more video frames into the VRAM to support its quality, it may not work in real time anymore.

Thanks for the reply.
Confirm that I should address me on the X265 encoding by focusing on the performance of the multicore CPU, I have in mind Ryzen 9 5900x and RAM 3600 MHz, DDR4 (32GB), and insert a video card that costs less (RTX 2070)?
Thank you
