CaptionHub is a commercial cross-platform caption and subtitle editing program. It is browser based, and has built-in tools for quality control and validation. It makes extensive use of speech recognition [wiki link] to assist and speed up the process of captioning and subtitling.

Browser-based CaptionHub is a web application that works in most modern web browsers[ref]. It has a rich HTML 5 timeline editor and collaborative workflow tools, allowing individuals and teams to create original captions, and to manage the subtitle translation process.

Being based in the cloud is advantageous for large teams, working in multiple time zones. It is also very useful for version control: everything is only ever in one place, and changes are logged. Multiple people can log onto the same project and work on it alongside other users.

Quality control Captions and subtitles are often created to a specification. For example, many broadcasters will stipulate a minimum duration that captions must appear on screen. CaptionHub continually analyses captions, and warns the user if any specification limits have been breached.

Subtitle validation For subtitle translation, users can be assigned viewing rights or editing rights for a particular video. At any one time, many people can have viewing rights, but only one person can have editing rights. Viewing rights can be transferred between users

Speech recognition CaptionHub makes use of speech recognition to analyse the audio, and return an original language transcript. This transcript is then processed by CaptionHub in order to create automatically generated captions, timed alongside the video. Furthermore, if a transcript is supplied, then CaptionHub can use speech recognition to align that transcript with the video. In both instances, CaptionHub attempts to split up captions in the same way that a human would. For example, it won’t end captions on a conjunction.
