You should rethink the UX for modifying placement of script text. The automated transcription is good but not perfect. When it misaligns text with the video, correcting the placement of the script text above the main audio track is a bit of a nightmare. It constantly wants to edit the video itself. The "handles" for sliding the boundaries of the script text itself there are wildly unclear and inconsistent. Fairly straightforward use case: UX should be equally trivial: dragging and dropping and adjust bounds of text elements should be as easy as editing an audio clip in say, Pro-Tools, where such editing is trivial.
