Expert-Caption®

Closed Caption Insertion into AVC and MPEG Streams

 

Expert-Caption® inserts captions from plain text or captioning files into AVC or MPEG streams without transcoding the video. The tool supports CEA-708/HD, CEA-608/SD, DVD and other captioning formats and outputs transport or program streams. The resultant captioned streams are compliant with broadcast and onboarding standards for Video On Demand (VOD), CableLabs, ATSC, and Over-the-top (OTT) applications.

Captioning your files has never been easier. Just drag your uncaptioned video to Expert-Caption and the program will do the rest. The tool can also be run in the batch mode allowing you to automatically caption thousands of files or to integrate captioning into your video workflow.

Expert-Caption 7 includes compliant CEA-708/HD and CEA-608/SD captioning decoders that allow you to do a quality assurance pass of your captioned video before delivery.

Expert-Caption 7 includes compliant CEA-708 and CEA-608 captioning decoders that allow you to do a quality assurance pass of your captioned video before delivery. All languages that have a unicode font will be displayed on the CEA-708 window. The tool also includes multi-levels of captioning analysis from a quick property listing of the type of captions found in a video down to the actual control codes, timings, text and binary captioning codes found in a captioned stream.

The tool is very easy to use. Just drag the uncaptioned video stream onto the Expert- Caption icon and the tool will do the rest. For non-standard captioning requirements, you can simply drag your custom configuration file onto the Profile box before you start the stream update.

Expert-Caption includes solutions for a wide variety of captioning issues including re- syncing captions, editing captions, and transcoding caption types.

The tool will easily fit into your workflow via operation in the unattended batch mode.
