The AI-Transcription functionality requires a specific license. Contact our sales team if your installation does not offer the commands described in this section.
Ai-Transcriptions can be performed on previously recorded videos, right from within VideoSyncPro Studio. It generates a plain text file name *.transcript which holds only text without time information. You can also simultaneously create an *.srt or *.vtt sub-title file including the required time information.
