Hello, Duolingo! would be a great idea add the option for translate and embed subtitles in videos!
awesome! that'd be a great way to practice translating at speaking paces... more difficult for me than reading/listening to recordings. :) great challenge & great way to increase access for more people
You can follow Spanish videos that are subtitled in Spanish or English on Dotsub http://dotsub.com. It is also possible to translate the videos, and even if these are not in the form of exercises, it is exactly what you describe...
