DaVinci Resolve Studio Benchmark
For this test we are using DaVinci Resolve Studio and have taken a one hour 1080P (30,000Kbps) resolution video and exported it using MP4 format, H.264 codec, UltraHD resolution (4K) at 20,000Kbps using only the CPU. No effects beyond super-scaling, standard fade in from black at start, and fade to black at end have been used.
Handbrake X265
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.
