I got all the way through, captioning a video with a transcript was like playing Guitar Hero, but I couldn’t figure out how to save it. Once I did, the captions (.sub format) weren’t accepted by subtitle workshop so that I could convert them to .srt for Overstream use.
This shows big promise though, because with a transcript ahead of time, this captioning was realtime. It took 5 minutes to caption a 5 minute video.
