About this Hands-on Lab

**Thank you for your interest in this content. Unfortunately, this content is no longer being updated and some of it may be out-of-date.**

In this hands-on lab, we are going to create a video transcoding pipeline using the Elastic Transcoder service.

Elastic Transcoder is a media service designed to be a highly scalable, easy-to-use, and cost-effective way to convert (or “transcode”) media files from their source format into various formats and qualities. The Elastic Transcoder service also operates in a serverless fashion, meaning you’re not responsible for allocating the underlying infastructure that is used to transcode these files.

In this lab, we will upload a sample video file to an Amazon S3 bucket and configure our Elastic Transcoder pipeline to transcode our video to 720p quality. (We’ve provided sample video files for you to use as your source media files.)

  7. Thumbnail Filename Pattern: Provide a naming scheme for your thumbnails (for example, "LakeThumbnail{count}").
  8. Click Create New Job.
Verify Transcoded Files Exist
  1. In the AWS Management Console, navigate to S3.
  2. Navigate to the bucket with the name containing "transcoded".
  3. Verify transcoded video files exist in the "transcoded" bucket.
  4. Navigate to the bucket with the name containing "thumbnails".
  5. Verify thumbnail files exist in the "thumbnails" bucket.
