Revision as of 21:25, 7 July 2010
On this page we will find a comparison of time-aligned text example files for several typical application areas. The example files are written in TTML, WebSRT and WMML and try to determine the simplicity/complexity of authoring these formats and whether they fall short in some requirements.
Note that the page is work-in-progress and there may be features in WebSRT and TTML that haven't been used yet and are noted as missing. Please provide feedback/improvements if you notice a mistake.
Subtitles
Simple, unformatted subtitles

Analysis:
- All three formats provide for the basic needs.
- You cannot specify the default language in WebSRT.
- You cannot specify the type of time-aligned text in WebSRT.

Analysis:
- TTML needs to use some XML namespace (e.g. xlink) to provide for hyperlinks.
- WebSRT does not provide for default language specification.
- WebSRT does not provide a role/type/kind attribute to signify that these are subtitles
- WebSRT does not provide for general styling, e.g. how to specify a background color. (TBD?)
- WebSRT does not enable reuse of styling between individual cues. (TBD?)
- WebSRT does not provide for URL hyperlinking in cues.
- WebSRT does not provide for special emphasis sections ("mark"-style).

Analysis:
- TTML has no margin attribute, just padding.
- I am unclear if WebSRT's specification of tbrl rendering and the margins is correct.
- For WebSRT, you have to repeat formatting for every cue.

Analysis:
- In WebSRT it is unclear what character/speaker a voice marker (e.g. <1>, <2>) maps to. (TBD?)
- In WMML it is unclear what the voice string maps to - needs metadata.

Analysis:
- Not sure if the style in the elements is only activated at the begin time of the element or if that requires different markup.
- Repetitions of bold and yellow in every cue in WebSRT - and will they get activated at the given time?

Analysis:
- All three fulfill the needs for chapter markers.

Analysis:
- In TTML we have to use xlink to specify representative images.
- In WebSRT we cannot specify representative images for a cue. (TBD?)

Analysis:
- TTML doesn't seem to have the metadata markers required to specify Dublin Core.
- WebSRT doesn't have functionality to specify metadata.
- WebSRT doesn't have functionality to specify slides/representative images.
