Nvidia nvenc vs nvidia nvenc hevc. Hevc h 265 or high efficiency video coding produces much higher standard than its predecessor with the same settings applied. Ffmpeg supports hardware accelerated decoding and encoding via the h264 cuvid hevc cuvid and h264 nvenc hevc nvenc modules. Nvenc in the gtx 10 series gpus provides superior quality than x264 very fast the most commonly used x264 preset. Sep 21 2018 1 49pm i ve noticed that even with nvenc my cpu ryzen 2700x is still hitting 100 usage but it still faster.

Ffmpeg stats f decklink i decklink mini recorder 4k 22 r 25000 1000 c v nvenc hevc preset hq profile v high level 5 1 b v 28000k minrate 28000k maxrate 28000k bufsize 35835k pix fmt yuv420p r 25000 1000 s 3840x2160 testuhdhevc25p422 ts but quality is bad it looks like it has only 500kb bitrate the detail is gone mosquito noise. Summing that up it seems wrong to state that nvidia nvenc hevc is better than x264. A 10 second 4k video on 4k. To encode a live source i use.

And it is that apart from certain proprietary technologies that improve graphics or performance huang s have been developing a specific function called nvenc for many years which has been updated after the jump from pascal to turing as an architecture and where ampere is expected. And in the new rtx 20 series nvenc performs better than x264 fast and on par with x264 medium a preset that requires an expensive dual pc setup. Nvidia rtx ampere gpus now support av1 decoding the first ampere graphics card to launch earlier this year the nvidia a100 accelerator does not have any video encoding capability. Transcoding pipeline with ffmpeg using nvidia hardware acceleration.

Nvidia has updated its nvenc and nvdec matrixes featuring just released geforce rtx 30 graphics cards. Nvidia graphics cards have a really interesting feature for their use by users who purchase them. For me with nvidia 1050ti is definitely faster nvenc perhaps even 30 faster if i remember correctly than amd ryzen 1600x. Nvidia nvenc acceleration for h 265 hevc h 264 while still being extremely popular and widely used isn t however the best encoding method currently in use.
