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

  • 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 and SDR video as well as LOG 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 Content Analysis

  • VQMINFMedia File Info Report Generator

  • VQBIFBIF (Base Index Frames) Files Verifier

  • VQCFACaptions Files Analyzer

  • VQFPVideo Frames Profiler

  • VQLPNAudio Loudness Profiler and Normalizer

  • VQLPCLoudness Profiles Correlator

  • VQPLAPicture Levels Analyzer

  • Pack 3. Target Application: Transcoding and CDN Optimization

  • VQMINFMedia File Info Report Generator

  • 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.

  • 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.
