Update: FFmpeg has HEVC encoding support using MulticoreWare libx265 now. Using patched FFmpeg with Chinese x265 support. Using standalone Chinese x265 then mux the resulting file with FFmpeg. This means with the latest Zeranoe build you can now do this: ffmpeg -i INPUT -x265-params crf=25 OUT.mov Using standalone MulticoreWare x265 and then mux the resulting file with FFmpeg. Anyways, these are a complete set of current possibilities of encoding HEVC in order of my recommendation: Directly using MulticoreWare libx265 with FFmpeg. Although the former started out first, it is practically dead now, and the latter is under active development and is supported by VideoLAN (the developer of x264). To make matters more confusing, there are two independent projects both named “x265”, one by a Chinese college student and is practically dead, and another by a commercial company called MulticoreWare. Of course you can still use some patched FFmpeg build, but it is not recommended. Now you can use ffmpeg directly to encode HEVC or use another encoder than manually mux that into.
