VQPT Packages
VQPT program modules can be purchased and used separately
or grouped for the following typical applications:

Pack 1. Target Application: Workflow Health Tests

• VQMINF – Media File Info Report Generator
  VQMINF reads a wide variety of media files (MOV, MXF, WAV, JPG, etc.) and creates Report in UTF8 JSON format.
  It can read HDR-PQ, HDR-HLG, LOG, and SDR video as well as video metadata.
  VQMINF also calculates unique vqminfEssenceID string and input file MD5 hash string.


• VQCBA – VideoQ Color Bars Analyzer, companion program for VQCB test patterns.
This module reads VQCB test pattern file at particular workflow test point, then checks video and audio levels,
detects color space distortions, dynamic range conversion footprints and measures AV Sync errors.


• VQCSA – Compression Stress Analyzer , companion program for VQCST test patterns.
This module reads VQCST test pattern file at particular workflow test point, measures VMAF scores for particular compression stress parameters and codecs settings, then builds compression stress response profile.


• VQMA – Video Analyzer for objective video processing chain integrity tests. This program reads VQMA test pattern file at particular workflow test point, then measures multiple video parameters and checks them vs. pre-configured tolerance values.

Pack 2. Target Application: Encoding, Transcoding and CDN Optimization

• VQMINF – Media File Info Report Generator
VQMINF reads a wide variety of media files (MOV, MXF, WAV, JPG, etc.) and creates Report in UTF8 JSON format.
It can read HDR-PQ, HDR-HLG, LOG, and SDR video as well as video metadata.
VQMINF also calculates unique vqminfEssenceID string and input file MD5 hash string.


• VQBIF – BIF (Base Index Frames) Files Verifier This module reads BIF thumbnail files, checks the parameters for compliance, and extracts numbered JPEG files as a reference decoder.
  


• VQBLA – Bitrate Ladder Analyzer
  
This module reads input media file, then checks multiple video parameters and builds the encoding quality score profiles for a given codec and preconfigured set of output frame sizes and bitrates.


• VQCSA – Compression Stress Analyzer , companion program for VQCST test patterns.
This module reads VQCST test pattern file at particular workflow test point, measures VMAF scores for particular compression stress parameters and codecs settings, then builds compression stress response profile.


• VQLPN – Audio Loudness Profiler and Normalizer
VQLPN measures and optionally normalizes the audio stream loudness parameters in accordance with Recommendation ITU-R BS.1770-4 (USA ATSC RP A85, EBU R128).


• VQTSF – Transcoding Segments Finder
  This module reads input media file and detects critical timeline segments positions (preferred key frames); it also measures content activities and builds related timeline profile.
  



Pack 3. Target Application: AV Content Analysis

• VQMINF – Media File Info Report Generator
VQMINF reads a wide variety of media files (MOV, MXF, WAV, JPG, etc.) and creates Report in UTF8 JSON format.
It can read HDR-PQ, HDR-HLG, LOG, and SDR video as well as video metadata.
VQMINF also calculates unique vqminfEssenceID string and input file MD5 hash string.


• VQCFA – Captions Files Analyzer
VQCFA reads .WebVTT, .VTT, .XML or .TTML caption file, measures caption parameters and checks them against the predefined, auto-switchable, and/or CLI specified, thresholds.
VQCFA also exports captions events timeline plot and full captions events listing text file.


• VQFP – Video Frames Profiler
VQFP reads media file, measures video frames active image formats, frame cadences, sharpness, noise level, video data and light level statistics, detects video segments, and calculate timeline profiles of video levels, light level, sharpness and details activity.


• VQLPC – Loudness Profiles Correlator, companion program for VQLPN module.
VQLPC reads two JSON report files created by VQLPN module (Reference and Test inputs), detects and compares momentary loudness time-line profiles of two inputs. Finally, VQLPC calculates the correlation of two inputs.


• VQLPN – Audio Loudness Profiler and Normalizer
VQLPN measures and optionally normalizes the audio stream loudness parameters in accordance with Recommendation ITU-R BS.1770-4 (USA ATSC RP A85, EBU R128).


• VQPLA – Picture Levels Analyzer
  
VQPLA reads SDR/HDR media file, detects video segments, and calculates timeline profiles of video and light levels.

Note that some modules are included in more than one pack, e.g., VQMINF is recommended for all three packages.
