This experiment achieved a PSNR of 8.31dB and SSIM of 0.249, which is considered poor quality. The compression ratio of 0.66x at 4.46 Mbps bitrate shows good progress.
The structural similarity index (SSIM) of 0.249 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.
