CEA708 requires regions to grow if text is bigger than cue box
Comment 1 Glenn Adams 2013-11-18 01:00:16 UTC 
Can you cite the clause and language that expresses this requirement?

> Can you cite the clause and language that expresses this requirement?

In CEA708, windows scale based on the font size. That's why there is the extensive anchoring functionality of the window with a specification about how the expand the text box when the font gets larger (see e.g. http://en.wikipedia.org/wiki/CEA-708#Anchor_ID).

Since regions in WebVTT are currently specified in percentage of video viewport size, I need to check if we can grow around different font sizes.

At the recent FOMS, we decided to also include em based region definition which would be much closer to the way in which CEA708 specifies windows. That should definitely fix this.
