TTML allows you to specify the root container extent (in pixels) on the root container; SDP would map this to the root video implying the aspect to be width:height. I assume you mean something else, so curious what the application is. -----Original Message----- From: Geoff Freed [mailto:geoff_freed@wgbh.org] Sent: 28 January 2013 14:10 To: public-tt@w3.org Subject: TTML and aspect ratio Hi, everybody: One of NCAM's partners (Netflix) is looking for a way to specify aspect ratio in a TTML file; however, TTML currently has no way of actually specifying aspect ratio. I took a look through the WG archives and saw that this topic has been discussed recently (http://lists.w3.org/Archives/Public/public-tt/2012Oct/0061.html) but it doesn't look like there has been any resolution. Is this feature under consideration? (Netflix has raised the same issue with WebVTT, and it looks like that spec will be including metadata for specifying aspect ratio: https://www.w3.org/Bugs/Public/show_bug.cgi?id=20566 .) Thanks. Geoff Freed NCAM/WGBH
