Only caveat is if the licensing ends up costing more than the price of a Maxwell-based NVIDIA Quadro without the two-encoder NVENC restriction, I may go that route even if I lose the ability to create HEVC with B-frames. Choose the "H264 (Nvidia® NVENC)" or "HEVC (Nvidia® NVENC)" option.

Then I encoded the files with the MainConcept (using P/Q 27) and x265 (using the Slower preset) HEVC encoders at 2Mbps and calculated the VQM score. mp4 -filter_complex "scale=1920:1080:flags=lanczos,libvmaf" -an -f null - H. $ ffmpeg -h encoder=hevc_nvenc ffmpeg version 4. 265, is a video compression standard developed as a successor to the H. 265 / HEVC (High Efficiency Video Coding) (decoders: hevc hevc_cuvid ) (encoders: libx265 nvenc_hevc. It has naught to do with OpenCL. 264 mp4 files. This allows you to use FFmpeg without detailed command-line knowledge. Codecs are different to containers like MP4, MKV and MOV because a codec manages the bitrate, resolution and frames whilst the container organizes and returns the data as sequence. 6 Best Free HEVC Converter Software For Windows Here is a list of best free HEVC converter software for Windows. 10-bit) HEVC encoding using the latest Nvidia NVENC SDK if anyone is interested in testing.
