This question was posted in response to the following article: http://helpx.adobe.com/premiere-pro/using/closed-captioning.html
Why can't we just use this functionality to create captions directly inside the program?
It isn't an efficient workflow, but you can create captions from scratch in Premiere Pro CC. Jut look for "File > New > Closed Captions..." and you'll be able to create a caption clip from scratch. We didn't concentrate on the captions-from-scratch workflow in this release because it wasn't our goal to become a full-blown captioning application. Instead, we just want to make the video editing process not lose captions.
