Comment (by GrahamArmfield):

 Here is my proposal for an ideal solution to this issue:

 1. When a user adds a video through the Add Media functionality, they
 should be allowed to also upload a caption file to accompany the video,
 or, to reference a previously uploaded caption file. An input field would
 be required for that.
 1. The URL of the caption file should be stored in the database against
 the video attachment - so in the post meta for the attachment.
 1. When user adds video that is already in the media library to page/post
 the URL of the caption for the video should be retrieved and presented to
 the user. Typically they would not change this, but they could. This URL
 will pass through into the HTML within the page/post.
 1. If user is within a page/post and wants to upload video they should
 also be able to upload or associate caption file with the video. As
 before, the URL for the caption file should be stored against the
 attachment rather than the page/post (as at present).
