Each IDI video features Closed Captioning, which can be activated by clicking the "CC" in the video player. Additionally, if you click the "Vimeo" wordmark, you can visit the video's landing page, which has a link to the transcript just under the video title.
The screenshot below highlights each of these feature's locations.
