Release of Stellar V6.0

On Sunday 7th August, Yella Umbrella released Stellar V6.0,  a major update for our Stellar AD, Dubbing and  Subtitle Timed Text editing tool.


We have added a range of new features for subtitling authoring, translation and QC to Stellar. These changes make Stellar a web based subtitling tool with all the feature of existing PC and Mac subtitling applications – and more.

Use Stellar to create subtitle files from scratch or convert existing files from all formats. Use Automatic Speech Recognition (ASR) tools to speed up the authoring process, choose from all the major ASR suppliers in a wide range of languages. Translate subtitles with the option of machine translation assistance.

Check and QC subtitle files using an advanced Rules engine built into Stellar. Speed up the QC process with advanced autocorrection tools for a range of common errors.
Define the file requirements Profile in detail and share these with your users via a central store. Profiles allow you to define all the style and QC rules for a client and have all your users work with the same rules, automatically.
Use new Layouts and hotkey maps to customise the look and operation of Stellar so your users can have the familiarity of their current subtitling software, but with all the benefits of the latest web based tools. Improve productivity and reduce retraining time.

See more on how the changes may effect you Here.

   Yella Umbrella have added new Speech-to-Text services to Stellar. 
The AD, Dubbing, Subtitle and Timed Text editing tool that runs in a browser. 

Yella Umbrella have just updated Stellar to support automatic speech to text (also known as Automatic Speech Recognition or ASR) services

from Amazon, Google and Speechmatics. These are in addition to the existing services from Apptek and

Language support has increased to 63 languages plus 13 dialects of English making automated speech to text a realistic option in most regions.

With accuracy rates reaching 90+ % on clear dialog, ASR is a realistic productivity tool in many localisation and access service workflows.

As well as being used for directly generating draft subtitle or script files ASR, can be used in more imaginative ways.

Stellar now supports automatic gap detection (finding gaps between dialog) to speed up the process of writing Audio Description scripts.

All ASR services produce subtitle files using either their own on Stellar’s subtitle splitting algorithms.

From 24th November all current users will have access to these new services.
