I have a use case where user will upload training video of application to repository through Pega UI. Pega's GenAI will be used to parse the video stream and create a training document (PDF/DOC) as per the given template as user prompts. Can someone share some insights on whether there's any OOTB feature in Pega to transcribe from video to text? Or if we need to use some external APIs for the same, please do share insights about the same.
