Best practice for transcripts when embedding videos from video hosting sites in Storyline

Hi all,

I'm interested to learn what you're doing about providing transcripts to meet accessibility requirements when embedding videos from external sites, for example youtube. With videos inserted directly into Storyline you can code the transcript into the player itself, with will play the transcript along the video which is brilliant functionality, but this just doesn't translate with embedded videos. 

Youtube does provide transcripts, and it's not a good user experience to send users out of the elearning to view the transcript in another browser. My thoughts are either copy and paste the transcript either into the Notes section of storyline 360 and provide the transcript on the page that way, or create a button and a layer to show the transcript for the video. Obviously this presents challenges, e.g. what if the video gets updated and the transcript no longer matches, but we can't legislate for every scenario I guess.

Was just wondering what you are practically doing in your courses with embedded videos in these scenarios?

Huge thanks!

Kaylea.
