When the <qc_video_metrics> parameter is added to your QC check, the source asset <original_source> is used as a reference file to quantitatively compare VQ using your choice of 4 industry-standard perceptual quality tools VMAF, PSNR, SSIM, and MS_SSIM. Comparing the report metrics of outputs with different codecs or encoding parameters can be an invaluable tool to help improve the playback experience. Custom threshold parameters can be configured to return alerts when the quality scores are higher or lower than the predefined targets.
