Video-Digitisation QC

VidiCert Benefits

  • Ensure that migration from an analogue or digital video tape to file does not introduce unwanted audiovisual defects to
    • preserve your media in best digital quality for the future
    • maximise its value for re-use
  • Detect earlier generation migration issues in order to re-migrate if earlier generation is still available
  • Video-Digitisation QC is especially crucial if destruction of video tapes is desired
  • Document audiovisual defects in preparation for a later restoration
Workflow Example

Video tape is digitised to file, either with a robotised or a manual ingest solution, either by you or by a service provider. The digitized file is analysed by VidiCert thoroughly and automatically in respect to specific visual and audio digitisation defects. Information about the location and severity of errors detected by VidiCert Analyser and optionally VTR-based error information is presented to the QC operator for verification. Verification of analysis results is highly efficient, enabled by the concise temporal information for segments with defects. So the operator can quickly decide, whether actions (e.g. cleaning of tape, cleaning of VTR, or re-ingest on an alternative VTR) need to be carried out. In case the digitisation is accepted by the operator, all defect information and any additional information provided by the operator during the verification process is documented for future use. This might be exported as XML,  PDF or a restoration-report.”
