File QC

We offer a number of applications to make file delivery of closed caption and subtitle files as quick and simple as possible.

Subtitle File QC Service

Our Subtitle QC application runs as an automated service that will detect typical file errors (such as overlapping timecodes or illegal durations) without any human intervention. The service will either Pass or Fail a file based on user specified parameters and produce a failure report detailing the detected problems.

An option is available to auto-correct typical file problems.

Subtitle Compare Service

Runs as a service application and compares a number of subtitle files to verify similarity’s and the probability that they all relate to the same programme. This application is extremely useful to anyone involved with the preparation or broadcast of multiple language subtitling.
