[solved, swf was corrupt] Is there any way to have a timeline animation for html5 output?

I work with a visual designer that is use to work with interfaces animations (intros, big characters, etc) and now we need to output html5. He used to work with flash, now is forced to make a tilesheet.
Is there any way to export a timeline animation that work with html?

[Update: the swf was corrupt and I thought that it was a feature not implemented]
