Dear Thierry, David, Please find my comments for the syntax part in WebVTT and few other areas in the following github issues: #360 - Term "WebVTT cue settings list" defined twice [0] #361 - Conformance Classes not complete [1] #362 - Chapter location for defining WebVTT chapter title text [2] #363 - Distinction between cue payload types [3] #364 - Term definition with empty content [4] #365 - Text color must be mandatory [5] In general the spec has improved especially by providing more examples and responding to comments by different reviewers. On the other hand it is still very difficult to review the spec because of the separation between data model, syntax, parsing and presentation. Although as a reviewer you actually need to review all parts together this is very time consuming. Especially for the parsing section you need to implement the spec text (if only in a formal pseudo algorithm). This is also a reason why I submit the comments so late and for the incomplete coverage of the review (apologies for that). Regarding the open issues: for most of them the group/editors need to decide if a fix/update is needed. Outstanding is the comment on text color. As commented in earlier discussions this is a critical requirement for accessibility and needs to be addressed.

August 2017 10:36 An: public-review-announce@w3.org Cc: public-tt@w3.org Betreff: Call for wide Review of WebVTT Dear All, The W3C Timed Text Working Group has recently published a new working draft of WebVTT: The Web Video Text Tracks Format [1]. The main use of WebVTT is for marking up external text track resources in connection with the HTML <track> element. WebVTT files provide captions or subtitles for video content, and also text video descriptions [MAUR], chapters for content navigation, and more generally any form of metadata that is time-aligned with audio or video content. The TTWG invites you to review this draft, and requests comments to be received by 22 Sept 2017. These comments will be used to fulfill the W3C Process [3] requirement for Wide Review of drafts, and Horizontal Review [4] prior to publication as Candidate Recommendation. If you wish to make comments regarding this document, please send them to public-tt@w3.org <mailto:public-tt@w3.org?subject=%5BWebVTT%5B> with [WebVTT] at the start of your email's subject. All comments are welcome, however the scope of review will be mainly focused on the new features introduced in WebVTT, since the First Public Working Draft [5] on 13 November 2014 which triggered a first Wide Review . A cumulative summary of all changes applied to this version since the WebVTT First Public Working Draft is available for your convenience [6].
