First, you watch some videos familiarizing yourself with the formatting guidelines and then you caption a 1 or 2 minute video using their captioning program. Once you're done, you send it off and within the week you'll hear back whether or not you've been accepted to continue to the next step in the application. If accepted, you'll caption another 2 videos, each about 2-3 minutes, and submit those. Then you should hear back within a week.
