This experiment achieved a PSNR of 21.42dB and SSIM of 0.628, which is considered poor quality. The compression ratio of 0.40x at 7.38 Mbps bitrate shows room for improvement.
The structural similarity index (SSIM) of 0.628 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.
