    VQCBA provides for automated cloud-based QA/QC, generating machine-readable JSON reports.
    In-depth analysis is possible via the VQV tool.

    Especially useful when streaming in multiple formats or when converting between formats.

    VQCBA reads media file YUV/RGB data, detects the relevant segments of video timeline, auto-detects test pattern type, calculates video and audio content parameters, compares the results with file metadata, checks the workflow distortions and conversion footprints, and finally produces machine-readable JSON Report.

    If input file contains continuous audio test tone, VQCBA detects this component and measures the audio test level in dBfs; result can be found in Audio Test Results section.

    Dynamic VQCB AV test pattern also provides for throughput Audio Gain and AV Sync Error measurements; results can be found in Audio Test Results section.

    In case of VideoQ VQCB test analysis, VQCBA decodes the VQCB QR code data and includes them in special Original VQCB Parameters section of the Report, thus allowing direct comparison of output parameters against the original ones.
