ISSUE-400 [EBU-TT-D compatibility] (raised)
  • 2015-07-31 15:31:08:
    *<Frans de Jong> Created issue 'Make multiRowAlign and linePadding testfile EBU-TT-D compatible' nickname EBU-TT-D compatibility owned by Frans de Jong on product TTML IMSC 1.0, description 'The current testsuite testfiles for multiRowAlign and linePadding are not fully EBU-TT-D compatible.

    I'd like to suggest the following changes to address this:

    Add to the tt element the attribute ttp:timeBase="media".
    Replace the named colours with hex values.
    Add xml:id attributes to the subtitles.

    Below are versions of the files taking these changes into account.
