File-Based Video & Audio Content Analysis

Automating Quality Control for File-Based Content

Automated quality control for file-based content

Content Analysis for Quality Control (QC) of file-based video ingested from different sources, encoded at different bit rates / formats and utilizing different compression standards for SD/HD, VOD or IPTV delivery presents considerable challenges to QC teams.

Cerify is a fully automated system for verifying/checking file-based content prior to transmission or use. Solutions range from windows-based PC standalone workstations to enterprise-wide solutions that interface to 3rd party automation or asset management systems.
