Let's assume you have a video of a customer testimonial from a conference where a person talks about their experience with a product. You uploaded this video to Azure Video Indexer for analysis. (1) Speech-to-Text Transcription: Azure Video Indexer can convert the spoken words in the video into a textual transcript. For instance, if the person says, "I really loved the product; it has made my life so much easier," the service will generate the following transcription:
[00:00:05.780 --> 00:00:10.520] "I really loved the product; it has made my life so much easier."                
(2) Face Detection: Azure Video Indexer can identify faces in the video and track them across frames. For example, if the customer testimonial video features the speaker and some audience members, the service will detect and label the faces of the speaker and the audience.

(3) Scene Detection: Video Indexer can automatically detect scene changes in the video. For instance, if the video switches from showing the speaker to showing the product in use, it will mark these scenes accordingly.

(4) Sentiment Analysis: By analyzing the speaker's speech and facial expressions, Video Indexer can determine the sentiment of the speaker. For instance, it can detect that the speaker expresses positive sentiment while talking about the product.

(5) Named Entity Recognition: Azure Video Indexer can identify and categorize named entities in the video, such as product names, brand names, or even names of people mentioned by the speaker.

(6) Keywords and Topics: The service can generate keywords and topics from the content of the video. For example, it might identify "product review," "customer testimonial," and "conference" as relevant keywords and topics.

(7) Insights Timeline: Azure Video Indexer generates an insights timeline, providing an overview of the key events, emotions, and topics at various timestamps in the video. This allows you to quickly navigate to specific points of interest in the content.

These results give you valuable insights into the video content without having to watch the entire video manually. Azure Video Indexer can be a powerful tool for content creators, marketers, and businesses to analyze and extract meaningful information from their video and audio assets efficiently.
