h.265 HEVC with NVENC and GTX 970

[benjos]

Hi everyone,

I'm a new user and I'm trying to convert .m2ts into h.265 using GPU acceleration. After I checkmark GPU, MediaCode automatically chooses NVENC and H.264 (which I then change back to H.265). I have two Nvidia GTX 970 in SLI and I'm using the newest driver 350.12 and I installed CUDA Toolkit 7 (but I only chose to install the CUDA toolkit instead of everything).

When I try to encode, I get error 014. I can encode using the x265 encoder and it uses my CPU but speed is 0.51x. I would like to use the GPU for faster encoding for H.265. Please advise.

Thanks!

There is still some known issue to be solved with NVENC's H.265 encoding.

Try using average bitrate/constant bitrate or constant QP. The only settings don't work for nvenc.

I cannot seem to shake the error either. I have an MSI 980Ti card.
Am still confused though if I need to download the separate NVENC update even though I installed the full version. Even if I tried, the site is not downloading it. It shows just one mirror that is clickable but the download never starts.
