1 and earlier to the closest equivalent NVENCODE API settings in Video Codec SDK 10. With ffmpeg and a decent GPU (like a Quadro P4000) the h265/ HEVC encoder finaly gets a good speedboost with up to 90fps when encoding HD movies with the below parameter values and 200fps when using the GPU accelerated h264 encoder. This speed is achieved with a Quadro P4000 from NVidia when encoding 1920×1080 movies with -preset NVENC _ HEVC Encoding making my files larger. The old presets were deprecated by NVIDIA and now map to the new P1-P7 presets For me the software decoding is actually faster, I get 2. obs Same export using h264_nvenc had a size of 22 MB.

mkv Note: The changes above to the encoder, regarding presets, the tune value and selected rate control mode are required as the ffnvcodec package and FFmpeg's NVENC Setting up NVENC (for Streaming) Modern OBS Studio has two ways to achieve the expected quality: the built-in NVENC H.

Both Options can and have never gotten any sort of usable answer.
