VQMPC tests usage at Olympic Games proved that they are extremely useful for live sport coverage and other workflows requiring streaming in multiple formats or AV format conversions.
VQMPC tests provide for semi-automatic AV levels and AV sync measurement by VideoQ tools.
With a VQMPC test you can instantly check that the video circuit is active, workflow parameters are normal, and audio is in sync.
The leading OTT providers use VQMPC test to validate playback performance globally.
The layout, components and appearance of the SDR variants of VQMPC test pattern suite are similar to the HDR variants, which makes much easier the usage of the whole VQMPC suite in modern mixed formats environments.
VQMPC suite includes 9 combinations of:
For a given frame size each package includes 3 sub-sets of media files of 3 dynamic range formats: HDR-PQ, HDR-HLG and SDR.
For a given dynamic range format each sub-set includes 8 variants with different frame rates:
23.976, 24, 25, 29.97, 30, 50, 59.94 and 60 fps.
Each media file is produced either by a lossless, variable bitrate encoder
or by a relatively high-bitrate, but lossy, encoder (order options).
