The main goal of this report is the presentation of a comparative evaluation of the quality of new HEVC codecs and codecs of other standards using objective measures of assessment. All test video sequences were 1080p video sequences. The comparison was done using settings provided by the developers of each codec. Nevertheless, we required all presets to satisfy minimum speed requirements. The main task of the comparison is to analyze different encoders for the task of transcoding video—e.g., compressing video for personal use. The comparison was performed on Core i7 6700K (Skylake) @ 4Ghz, RAM 8 GB, Windows 8.1. Set of test video sequences was selected using method described in Appendix D. More than 30000 videos were automatiucaly analyzed and clusterized and 27 of them were chosen to represent theirs clusters. Quality of encoded video seqeunces was estimated using YUV-SSIM objective quality metric (see Appendix G.1)
