New free powerful program for formal video quality measurement is
released now: MSU Video Quality Measure 0.71 BETA
http://www.compression.ru/video/quality_measure/video_measurement_tool_en.html
Supported video formats:
* *.AVI
* *.YUV (scientific)
* *.BMP
Supported metrics (and color spaces):
* PSNR (Y,U,V,L,R,G,B) - most popular
* Delta (Y,U,V,R,G,B)
* SSIM (Y) - new
* VQM (Y) - new
* MSU Bluring (Y,U,V) - new
* MSU Blocking (Y,U,V) - new
Main features:
* 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" - 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 programmes can use this feature for tuning (fast codec/filter update testing). For example, we use last mode (comparative analysis) for tests before new version release for added bugs fast search.
Program available for free download on:

Any comments and notes are welcome! :)
Enjoy! ;)
P.S. Video quality human perceptual free tool coming soon! Stay online! ;)
