With Vantage, you can choose a preset and customize your HEVC encode even further by inserting command-line arguments ffmpeg -y -i input. The parameters will be listed in the format used by the standalone x265 binary, but all of the parameters should also be usable in x265 Documentation Introduction. Run this command for x265 conversion: ffmpeg -i input. ts In the above example, -bufsize is the "rate control buffer", so { "x265-params", "set the x265 configuration using a :-separated list of key=value parameters", OFFSET(x265_opts), AV_OPT_TYPE_STRING, { 0 }, 0, 0, VE}, { NULL } For getting available x265-params check x265 --help. 168. mov -c:v h264_nvenc -pix_fmt yuv420p -preset slow -rc vbr_hq -b:v 8M -maxrate:v 10M -c:a aac -b:a 224k outmovie. mp4 -c:v libx265 -vtag hvc1 output.
