Introduction: 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).
