ISSUE-22: window fade in/out not supported?

window fade in/out

window fade in/out not supported?

State:
PENDING REVIEW
Product:
TTML2
Raised by:
Pierre-Anthony Lemieux
Opened on:
2008-12-05
Description:
Interoperability with current practice in US captioning has been expressed as a desirable goal, however CEA 708 offers window fade in/out - no equivalent mechanism exists in DFXP for intermediate animation, but could be approximated in discrete steps using set and opacity.

Should intermediate animation of opacity be added for use on regions?

Add support for continuous animation using animate element. https://dvcs.w3.org/hg/ttml/rev/1d13586de640

[glenn]: submitter should review proposed changes and assess if use case still holds

[pal]: Mike Dolan: 708 requires display effect (SNAP, FADE, WIPE) effect_direction (LTR, RTL, TTB, BTT) effect speed (.5 - 7.5 seconds)

[glenn]: need to check how well the animate semantics map to CSS3 Animation

19 Sep 2013, 14:38:46

708-driven animation requirements also include Issue-72.

I believe we should attempt to address these with some simple animation control attributes that map to 708 semantics and not introduce a complex animation infrastructure.

This issue has been addressed by the adding of the <animate/> element, and should be closed.
