Detector Packages for Audio-Visual Errors
The QUADRIGA•Video workflow can be extended with Cube-Tec’s detector packages for an analysis of the audio-visual baseband signal during file-based quality control to identify all the defects that slip through during ingest.
Two separate packages can be licensed: One package that aims for the detection of artefacts in digital video material, such as Digibeta drop-outs or MPEG Macroblock issues and the second detector package specialized for issues generated by analog tape machines.
The results of the baseband analysis will be combined with metadata that has been created during QUADRIGA•Video ingest and can then be fed into the QUADRIGA•QC View for manual QC assessment. The results of the baseband analysis can also be used to trigger automatic workflow decisions.

Workflow Configuration
Within the QUADRIGA•Video workflow configuration frontend the operator can select the different QC analyzers separately.
For example if video files come straight of an analog Sony Betacam VTR the Digital Video Drop-Out analyzers may be turned off temporarily to save computable resources.
