Release of Stellar Automatic Subtitle Alignment
With so much media moving from a broadcast environment on to streaming service there is a huge challenge to repurpose subtitles originally created for broadcast to forms suitable for a streaming platform. Often the video has been edited to remove ad-breaks or to add or remove colour bars, slates, headers or bumpers. Any change in the video run length or timing requires a matching edit in the associated subtitle files, of which there may be many different language versions. This process is known as Conforming.
As well as subtitle file format conversion Stellar from Yella Umbrella now provides automated realigning (conforming) of the subtitle file to match the new, edited, video. Using Speech to Text web services from Amazon and others, Stellar realigns the subtitles to match the dialog detected in the new video edit. Subtitles can be moved or deleted, any edits that can’t be done automatically will flag as errors.
When moving a complete archive from broadcast to streaming there can be tens or hundreds of thousands of subtitle files to conform. Stellar greatly speeds up the process so reducing costs and improving productivity.
