This utility takes the JSON from Amazon AWS Transcribe and outputs a VTT file. There is a Firefox webdriver for MacOS included to test the outputted VTT file, which will prompt for a link to the video and display the video with subtitles on a temporary local server. If you would like to test on a different operating system, follow the documentation here to replace the driver on your system PATH.
The outputted VTT file is saved to output/output.vtt. Easiest way to run is place the JSON from AWS inside the root folder, and then simply type the name of the file when you are running the utility.
