This experiment achieved a PSNR of 20.78dB and SSIM of 0.616, which is considered poor quality. The compression ratio of 0.47x at 6.21 Mbps bitrate shows room for improvement.
The structural similarity index (SSIM) of 0.616 indicates that the reconstructed video maintains acceptable structural similarity to the original. This metric is particularly important as it correlates better with human perception than PSNR alone.
