Captions inside media files can be crawled and indexed by search engines, and can be exposed to screen readers. Captions in a separate file are indeed a less optimal solution in that they aren't necessarily clearly associated with the video file, they can't be viewed if the user disables scripting, they don't get saved with the video file so accessibility is lost when repurposing the video file, and their accessibility story is much more dependent on technologies like ARIA (and therefore there is a higher chance that sites will fail to make them suitably accessible). In general, I would recommend using captions inside media files, as Maciej suggests. > Several of us are working on some of these wild suggestions and I hope > for the second version of HTML5 we will have some implementations > available.
