Ffmpeg encode to h2645/17/2023 Obviously I would like to keep the low file size, but take advantage of the GPU to process it 15X faster.Īnyone else have any experience with this video codec? My understanding is that the difference between libx265 and nvenc_hvec is not the algorithm that is used to do the compression, but that it utilizes the GPU to accelerate processing. Doing the exact same command with libx265 gives me a file size of only 68M. My input file is 269M and when I use the nvenc_hevc it grows to 394M. Using the library libx265 I am getting about 85fps when working on a file that is 720p, but if I use the nvenc_hevc I get around 600-700fps I am working with x264 files to x265 and wanted to go faster. I got a new Nvidia GPU to speed up my video encoding.
