=Benchmarking= Being a standart, HEVC encoders and decoders can be implemented with various features and in different ways, that is why benhcmarking for various implementations is needed. Here in the table below listed approaches to benchmarking the HEVC encoders emplementations In the table below results of MSU Video Codecs Comparison. Participants are rated using BSQ-rate (enchanced BD-rate). Set of videos is encoded with various bitrates, after that quality is measured using the objective metrics such as SSIM or VMAF. Values are proccessed in such a way that they present rating based on how much bitrate could be saved or wasted to achive quality compared to codec that was chosen as reference (in the table below it is x265). That means, for exmaple, that if Tencent V265 Encoder target bitrate was set lower, meaning lower encoding quality, by 22% it could have same perceptual wuality as x265.
