IT WORKS!!!

converting aussie DVB-T to Apple mp4 i get around 12x speed and the quality is good.

all this with a lowly GTX650

Well done!

Disable "denoise" option on Picture tab to improve ssim.

denoise auto - SSIM: 27.06717304
denoise disabe - SSIM: 28.03792632

The difference in quality between the implementation of your and "rigaya" is visible to the eye.
SSIM values in a difference of almost 4.706 (!) points

You may have made a mistake somewhere?

Note the trees in a static picture and in motion. It can be seen that a problem in encoder.

The 3D denoiser makes the picture more clear, stable and efficient for compression. It's good for perception quality but makes SSIM lower (less identical to original).

You watched the video has attached a link?
can be used in mediacoder CUDA, and not NVENC.
Difference in quality, noticeably without SSIM.
SSIM values, I gave as an example of how great the difference.

nothing to do with denoiser is not here.
I suggest to replace your NVENC from rigaya

Does anyone get NVENC with H.265 working?
I tried to use several parameters but always get error14.

Using GTX970 with lastest Driver (347.52)
Using MediaCoder x64; 0834.5695 with NVENC update pack

I have an laptop and performance is lower that expectec.
0.5fps. :mrgreen:
encoder engine: NVENC
GPU info:
GTX 860M 4GB
640 shaders

paired with:
i7 4710HQ

i post this because think that's is a isue.

If i select cuda option, performance is the same.


Sorry for my english (only speak spanish :lol: )
Lenovo y50-70 i7 4710hq + gtx 860m 4GB GDDR5 + 16GB DDR3l 1600
