Free program for video quality measurements. Supports different input
formats (AVI, AVS, YUV, BMP) and metrics (PSNR, Delta, VQM, SSIM, MSU Blurring /
Blocking, MSE, MSAD). Main features: results are saved in *.CSV (can be opened
everywhere), all metrics are visualized, comparative analysis (comparison of
three files: original, and two
other, for example processed by different codecs).
Program allow to answer on questions:
1) One codec has more blurring than another. On what frames? Average mark?
2) One codec has more blocking than another. On what frames? Average mark?
3) One codec has more lower quality than another. On what frames? Average mark in PSNR, VQM, SSIM?

Correspondent "bad frames" are saved automatically into BMP files.
