During the textAV event with a small team we did the requirements gathering based on Joseph Polizzotto's presentation and oTranscribe.

In the following weekend I built an app that considerably speeds up and simplify the captioning workflow.

  • It auto transcribes
  • It adds punctuation automatically
  • User can then correct the text
  • It auto segments and aligns to create caption file.

Demo

See demo here for demonstration purposes (click load and then align).

It auto transcribes using speech to text service to give you a first draft, it auto adds the punctuations, you can review and correct, and when you click align it segments and auto aligns(very fast) to create a caption file (srt but could support more format) similar to youtube captioning editor.

Gives you a preview of the caption file, with clicable timecodes that take you to that point in the video.
