Autotexting like TV and YouTube. It would be great, if you can capture a web-seminar (as a student etc), and have it teksted. Or a pod-cast. You have are already implemented "Capture Video", and can just add text to it. Text on video, and text on a single file, for editing and easy reading. If you can do it realtime, you can capture a window in Skype, Messenger, Hangouts, Zoom etc, and have it texted in another window. After this, you can implement translation to the text.
