Intelligent question-and-answer over training videos

Solution Summary
This solution enables intelligent question-and-answer over training videos by automatically extracting video content, transforming it into structured knowledge, and grounding responses in Azure AI Search for use in Copilot Studio.
Training videos uploaded to SharePoint Online are automatically processed end-to-end using event-driven Azure services. Video content is analyzed using Azure AI Content Understanding (Video Analyzer) to extract transcripts, summaries, and contextual markdown. The extracted information is normalized and indexed in Azure AI Search, enabling fast, accurate, and scalable retrieval.
Users can then ask natural-language questions in Copilot Studio, receiving answers grounded directly in the video content.

No files, tests, or entry points are named. Start by reviewing the proposed event-driven Azure workflow, including SharePoint Online, Azure AI Content Understanding, Azure AI Search, and Copilot Studio. Done should mean that training videos are processed into searchable knowledge and that questions receive answers grounded in the video content.
