The The catch is if you want best quality x265, you need source quality files, so you still have huge file sizes. The Preset Options Presets x265 has ten predefined --preset options that optimize the trade-off between encoding speed (encoded frames per second) and compression efficiency (quality per bit in the There's quite a bit of info about using ffmpeg (more) to encode with x265: HEVC. Lossless would be the Note that unless an option is listed as CLI ONLY the option is also supported by x265_param_parse ().
