Free program for video quality measurements. Supports different input formats (AVI, AVS, YUV, BMP) and metrics (PSNR, Delta, VQM, SSIM, MSU Blurring / Blocking Measure).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.
- Everybody in 5 minutes is able to demonstrate that one codec is better than another! It's easy:
- Set "comparative analysis" and select original, sequences compressed 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 difference in values of the metric (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).
- Plug-ins interface gives user possibility to create their own metrics.
- Masking (calculation of a metric for the part of a frame)
