This is an example of a nice video with some significant faults.
1) No captions. The words of the narrator are not available if you can't hear.
2) No audio description. e.g. the gymnastics portion of the video is unavailable if you can't see.

Note that there is also less need for a separate audio description in a short video like this if the narrator's main script is repuposed to describe more of what is happening in the video.
And yes, Twitter supports .SRT files. At least if you're posting ads or using their media studio.
