Show answer & explanationAnswer & explanation
Correct answer: A. Azure Video Indexer
Azure Video Indexer is specifically designed for extracting rich insights from video and audio content. It automatically performs tasks like speech-to-text transcription, sentiment analysis, keyword extraction (for product mentions), and even can identify scenes and keyframes for highlight reel generation, making it the most comprehensive solution for this scenario.
Why the other options are wrong
- B. Computer Vision primarily analyzes static images, not comprehensive video content.
- C. Custom Vision is for training custom image classification/object detection models, not video analysis.
- D. While Text Analytics can do sentiment and Face API can detect faces, Video Indexer provides a unified platform for all these video-specific insights and more, including auto-summarization/highlight generation.
