Free program for video quality measurements.Supports different formats, metrics.
EditBy: 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.

2.7.2
[*] Fixed bug causing incorrect metric values, when using 3SSIM and MSSSIM simultaneously
[*] Fixed bug causing incorrect PSNR metric values in CSV files
[*] Fixed bug causing no metric calculation for large (>4gb) files
[*] Not existing directory specified in -cod parameter will be created now and processing will not cancel.
[!] Program crashes due memory lack when -metr ALL specified with large (i.e. 1280x720) video frames. you can free download MSU Video Quality Measurement Tool 2.72 now.
