W3C Community and Business Groups
This group will work on text tracks for video on the Web, applied to captioning, subtitling and other purposes. This group plans to work initially on:
1) Documenting a semantic model underlying the caption formats in use, notably TTML, CEA 608/708, EBU STL, and WebVTT.
2) Creating a community specification for WebVTT.
3) Defining the mappings between WebVTT and some selected formats, including at least TTML (W3C/SMPTE), and CEA 608/708.
4) Creating web developer reference and tutorial material, including worked examples.
5) Creating a test suite and/or tools.
A possible transition to REC-track for some of these document(s) is envisaged and that possibility will be used to guide the work and procedures.
The group may produce recommendations for work in other groups, such as CSS, HTML5, and TTWG.
Just joined this group. Great to see some faces from the “old days”.
I’m especially interested in using text tracks to support lectures where technical text (especially programming code and markup) is being discussed and illustrated, but I’m also interested in a broader interpretation of ‘text’, for example music scores, mathematical equations, scientific calculations and other non alpha-numerical glyph-based media, which might usefully be synchonised with video.
Sorry I joined so late but was unaware of this important initiative.
We at SubPLY are eager to add our experience and knowledge to the group in any manner possible.
Good Luck !

Welcome to the newly started “Web Media Text Tracks Community Group” – also by some called the “Captioning CG” or the “WebVTT CG”.
Our work will encompass more than just captioning and more than just WebVTT, therefore the broader title. But we will indeed have a large focus on captioning to begin with and one core aim is to make sure WebVTT offers all the features that a professional captioning format requires.
We will start discussions once representatives of the major browser vendors have joined. It is their implementation work that we want to guide through this group and their questions that we want to address.
Note that I’ve started a WebVTT twitter channel where I am planning to post about the discussion results and spec changes that we make in this CG. If anyone would like to help me with the twitter channel, let me know and I can add you as an author.
I’m looking forward to a flourishing and very productive new CG!
