Metriсs
Most modern video codec comparisons use objective video quality models. They can be classified as:


 * Full reference methods (FR):
 * PSNR (Peak Signal-to-Noise Ratio)
 * SSIM (Structural SIMilarity)
 * VMAF (Video Multimethod Assessment Fusion)
 * MOVIE Index (MOtion-based Video Integrity Evaluation)
 * Reduced reference methods (RR):
 * SRR (SSIM Reduced-Reference)
 * ST-RRED
 * No-reference methods (NR):
 * NIQE (Naturalness Image Quality Evaluator)
 * BRISQUE (Blind/Referenceless Image Spatial Quality Evaluator)
 * Video-BLIINDS

Also, many benchmarks evaluate the subjective video quality.
