Build 2024: Azure AI Video Indexer integration with language models for textual video summary

We are thrilled to introduce textual video summarization for recorded video and audio files, powered by large and small language models (LLM and SLM). 

application developers can leverage APIs to create textual summaries for audio and video files, anywhere.

Data analysts, instead of watching entire videos, can benefit from concise summaries of video and audio content and adjust it to their needs. 


Azure Video Indexer, a cloud and edge video solution, enables textual video summarization with the following build announcements:

Preview at the cloud: Textual video summarization in Azure AI Video Indexer powered by Azure Open AI

The feature of textual video summarization in Azure Video Indexer, cloud edition is powered by Azure Open AI. This innovative addition allows customers who have created an AOAI resource in Azure, to seamlessly integrate it with Video Indexer. By leveraging deployments such as GPT4, users can now enjoy concise textual summaries of their videos, presented as an insightful extract alongside the player page. The video summary not only enhances the viewing experience but also empowers video analysts to tailor the summary's nuances and to align with specific business requirements.

Preview at the edge (on premise): Extend Azure AI Video Indexer enabled by Arc with integration with SLM through Phi3

The preview version of Azure AI Video Indexer enabled by Arc now includes integration with SLM through Phi3. The innovation containerizes both the Azure AI and Phi3 models, providing video analysts the ability to perform video summarization. It represents a significant stride in our generative AI capabilities utilizing the cutting-edge Phi3 model at the edge. The Phi3 model opens new avenues for AI applications, especially in settings where computing resources are limited, by offering a more streamlined and efficient approach to video analysis.

 The Phi3 model, developed in line with Microsoft's Responsible AI principles and trained on high-quality data, is a testament to our dedication to safety and excellence in AI. It's a lightweight, state-of-the-art model designed for long-context support, making it ideal for generating responsive and relevant text in chat formats.

Use cases for video summarization across industries

  • In education, summarized videos can serve as study aids, allowing students to review lecture content quickly. The capability can distill lengthy training videos into key takeaways, saving employees' time and improving knowledge retention, e.g., in corporate trainings.
  • In media, it helps in quickly understanding the content of large video libraries, like movies or series, without watching the entire footage. This can be particularly useful for editors and content creators who need to create promos or trailers.
  • In manufacturing, summarized videos can serve as training material or evidence of compliance with regulatory standards and can quickly highlight parts of footage where potential quality issues are detected on the production line.
  • Retailers can use video summaries to understand customer traffic patterns and preferences without watching hours of footage.
  • In modern safety, textual summaries can pinpoint instances of theft or suspicious behavior, streamlining the review process for security teams, enhance the review process of training exercises, identifying key moments for analysis and improvement.
