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

    Pack 1. Target Application: Workflow Health Tests

  • VQMINFMedia 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.

  • VQCBAVideoQ 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.

  • VQCSACompression 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.

  • VQMAVideo 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: AV Files Conversion, Encoding and Transcoding

  • VQMINFMedia 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.

  • VQBIFBIF (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.

  • VQCHDR-SDR Converter
  • This module reads media file(s) and converts HDR-PQ, HDR-HLG, or SDR dynamic range and color space format to the specified output format.

  • VQBLABitrate 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.

  • VQCSACompression 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.

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

  • VQTSFTranscoding 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

  • VQMINFMedia 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.

  • VQCFACaptions 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.

  • VQFPVideo 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.

  • VQLPCLoudness 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.

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

  • VQPLAPicture 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.
