Video quality metrics are used to evaluate the fidelity of video content. They provide a consistent quantitative measurement to assess the performance of the encoder.  Peak signal-to-noise ratio (PSNR): A long-established quality metric that compares the pixel values of the reference image to a degraded one.  Structural similarity index measure (SSIM): Compares luminance, contrast, and…
