: x265 --preset slow --crf 22 input.y4m -o output.hevc
: You can choose from ten predefined presets (from ultrafast to veryslow ) that trade encoding speed for compression efficiency. The default is medium . Rate Control :
: x265 --bitrate 5000 --vbv-maxrate 5000 --vbv-bufsize 10000 input.y4m -o output.hevc
