A typical use case is when you want to detect a known face in a video stream. Amazon Rekognition Video uses Amazon Kinesis Video Streams to receive and process a video stream. The analysis results are output from Amazon Rekognition Video to a Kinesis data stream and then read by your client application.<\/p>\n\n\n\n<h2>Working with stored videos<\/h2>\n\n\n\n<p class=\"has-text-align-justify\">Amazon Rekognition Video is an API that you can use to analyze videos. With Amazon Rekognition Video, you can detect labels, faces, people, celebrities, and adult (suggestive and explicit) content in videos that are stored in an Amazon Simple Storage Service (Amazon S3) bucket. Moreover, Amazon Rekognition Video is categorized as media\/entertainment and public safety.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-justify\">Previously, scanning videos for objects or people would have taken many hours of error-prone viewing by a human being.

We have explored that we can use Amazon Rekognition when needed to perform facial analysis at scale without worrying about infrastructure or training a model for identifying persons of interest, cataloging a digital library, creating a face-based employee verification system, or performing sentiment analysis. We will discuss more of AWS Rekognition and its other implementations in our upcoming blog. Stay tuned to keep getting all updates about our upcoming new blogs on AWS and relevant technologies.&nbsp;<\/p>\n\n\n\n<p>Meanwhile \u2026<\/p>\n\n\n\n<p><strong>Keep Exploring -&gt; Keep Learning -&gt; Keep Mastering<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-justify\">This blog is part of our effort toward building a knowledgeable and kick-ass tech community.
