Elecard Video Quality Estimator description
Calculate video quality metrics, such as PSNR, NQI, VQM and SSIM. Elecard Video Quality Estimator is a software utility that helps you compute video quality metrics such as SSIM, PSNR, VQM and NQI. It has been designed and implemented for reverse engineering and analysis.

Here are some key features of "Elecard Video Quality Estimator":

· Display of the comparison results
· Calculation of the video quality metrics (PSNR, NQI, VQM, SSIM)


Specifications:
· YV12
· UYVY

Requirements:

· SSE-enhanced CPU
· 512 MB RAM
· Any VGA card


Limitations:

· 21 days trial
· A maximum of 100 frames

Free program for video quality measurements. Supports different input
formats (AVI, AVS, YUV, BMP) and metrics (PSNR, Delta, VQM, SSIM, MSU Blurring /
Blocking Measure). 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.

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! Its 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).

Elecard StreamEye (StreamEye) tools are powerful applications designed for media professionals and prosumers to analyze video quality, troubleshoot problems in the encoded stream for further video compression optimization, and ensure compliance to the video standards.

Elecard StreamEye tools comprise Elecard StreamEye application, Elecard YUV Viewer, Elecard Video QuEst, Elecard Stream Analyzer, Elecard Buffer Analizer.

StreamEye application provides the user with a visual representation of the encoded video features and a stream structure analysis of MPEG-1/2/4 or AVC/H.264 Video Elementary Streams (VES), MPEG-1 System Streams (SS), MPEG-2 Program Streams (PS) and MPEG-2 Transport Streams (TS).

YUV Viewer is designed to view YUV data sequence in YUV video files, compare files against one another to find out if binary images match, and view the result of comparison. The application also allows the user to calculate quality metrics, such as PSNR, NQI and VQM.

Elecard Video QuEst allows the user to calculate video quality metrics, such as PSNR, NQI, VQM and SSIM. It has been designed and implemented for reverse engineering and analysis.

Elecard Stream Analyzer is a powerful tool designed for syntax analysis of encoded media streams and presentation of the analysis log in a human readable form. Stream Analyzer operates with MPEG-1 Video/Audio, MPEG-2 Video/Audio, AAC, AC-3 and AVC/H.264 files.

Elecard Buffer Analyzer allows analyzing of the decoder video buffer parameters.

Whether you are a multimedia application developer, codec writer, system engineer or QA team member, Elecard StreamEye Tools package is essential for you to perform an effective in-depth analysis of video sequences.
