x264 HD Benchmark
x264 HD Benchmark is a benchmark that allows you to measure how fast your PC can encode a 1080p video clip into a high quality x264 video file. It allows for an easy comparison because everyone running it will use the same video clip and software. The x264 video encoder has a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make the x264 HD Benchmark an ideal tool in comparing the video encoding performance of different processors and systems.
HandBrake is a free and open-source transcoder for digital video files, originally developed in 2003 by Eric Petit. Since then it has continued to evolve. Included in its list of features is the ability to transcode existing video from x264/MPEG-4 AVC to x265/HEVC. For this test we are using a one hour length 4K x264 file and using the H.265 MKV 1080p30 preset transcoding it to 1080p resolution.
