Video Quality Estimator
Video Quality measurement tool designed to compare the quality of encoded streams based on objective metrics, such as PSNR, APSNR, SSIM, DELTA, MSE, MSAD, VQM, NQI, VIF, VMAF, and VMAF phone.
Compare two encoder versions
Use general stream parameters and 11 video quality metrics, and visually compare frames or separate blocks of the stream
Optimize your encoder
Analyze the quality of encoded video against a reference RAW stream and identify the code portions causing quality changes
Key Features
Calculate quality metrics: PSNR, APSNR, MSAD, MSE, SSIM, DELTA, VQM, NQI, VIF, VMAF, and VMAF phone
Visually compare frame differences across multiple modes (Compare, PSNR, PSNR Clip, Temperature, Subtraction, Horizontal split, and Vertical split)
Calculate metrics for 5 files simultaneously
Display essential statistics of encoded streams
Select ROI (region of interest) for metrics calculation
Automatically detect and select matching initial frames to synchronize streams for analysis
Switch between BT.601, BT.709, BT.2020 color gamut presentation
Synchronize streams across applications of Elecard StreamEye Studio set (Binding mode)
View comparison results in graphical format (including metrics, quantizers, frame sizes, bit allocation, and more)
Select little/big endian upsamplers for uncompressed video sequences
Choose the output YUV data format when saving decoded information
Automate workflows via the Command-Line Interface
Export data to CSV or JSON files
Video Quality Estimator is a part of StreamEye StudioElecard StreamEye Studio includes 4 standalone applications and command-line tools for all-around video analysis.
