A recent consulting project necessitated that I add objective quality measurements to the analysis. The tool I used was the Moscow Statue University Video Quality Measurement Tool (VQMT), which enables comparisons using Peak Signal to Noise (PSNR), Structured Similarity Index (SSIM), and the new Video Quality Metric (VQM), which I found most useful.
In this review on the Streaming Media Europe site, I discuss how VQMT works and why it’s so useful. If you do a lot of encoder or codec comparisons, you’ll find this $999 tool as invaluable as I did.
