MSU Video Quality Measurement Tool

MSU Video Quality Measurement Tool - Free program for video quality measurements MSU Video Quality Measurement Tool is a freeware tool designed to measure video quality. Supports different input formats (AVI, AVS, YUV, BMP) and metrics (PSNR, Delta, VQM, SSIM, MSU Blurring / Blocking Measure).

Features of "MSU Video Quality Measurement Tool":

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:

One codec has more blurring than another. On what frames? Average mark?

One codec has more blocking than another. On what frames? Average mark?

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.

Supported video formats:

*.AVI
*.AVS
*.YUV (scientific)
*.BMP (RGB24)
Supported metrics (and color spaces):
PSNR (Y,U,V,L,R,G,B) - most popular
Delta (Y,U,V,L, R,G,B)
MSAD (Y,U,V,L,R,G,B)
MSE (Y,U,V,L,R,G,B)
SSIM (Y) - new
VQM (Y) - new
MSU Blurring (Y,U,V) - new
MSU Blocking (Y,U,V) - new

Here are some key features of "MSU Video Quality Measurement Tool":

Results are saved in *.CSV (can be opened everywhere)

All metrics are visualized (very useful for codec and filter debugging)

Main feature for codec lovers: comparative analysis (!!!) Now everybody in 5 minutes is able to demonstrate that one codec is better than another! It's easy:

Set "comparative analysis" and select original, and sequences after compression with codec A and codec B (recommended more than 10000 frames).

Select metric (recommended Y-PSNR)

Select "Save bad frames" (in "Advanced" dialog you could specify for which sequence value of the metric must be greater) - pairs of frames with maximum metric difference (A>B) will be detected and saved.

Press "Process", find output frames and select best pairs

Upload frames to your favorite forum.

Done!

If you want to prove, that codec B is better than A just swap compressed files in metric form fields. :) Codec and filter developers can use this feature for tuning (fast codec/filter update testing).
