HandBrake

HandBrake is an open-source, GPL-licensed, multiplatform, multithreaded video transcoder, available for MacOS X, Linux and Windows. This software puts multithread CPUs to good use and it allows to transcode videos using different codec, like for instance h.264. For our test we have used a short 4K video file and transcode it with the h.264 and the h.265 codec using the so called high profile and the file is being saved in a MP4 container. The result you see below is average frames per second, where more is better.
