All videos are automatically transcribed by the system. Plotto offers a human transcription service where greater accuracy is required, or you can easily modify a transcript yourself.
There are two integrated transcription engines (IBM Watson and Bing) and you can toggle between them using the Transcription dropdown. If you edit a transcription file (or input a translation) this automatically gets saved as a new version - accessible by the same Transcription dropdown.
