Transcoding larger video files

To transcode large video files that a serverless code function can't handle, you need to use a dedicated transcoding service. This page demonstrates how to do this with AWS.

Transcoding large video files on AWS

There are three main services we'll be making use of here:

• AWS Elemental MediaConvert: the service that will actually perform the video transcoding
  
  
• AWS EventBridge: the service that will notify us when a transcoding job is completed, so we can automatically update our databases or whatever else we want to do.
  
• AWS Lambda: to receive notifications from EventBridge, and update our database with the newly transcoded video URLs.

Technically, you don't need Lambda and EventBridge here if you wanted to run a few videos through MediaConvert manually. However, unlike say the Lambda API, you can't schedule a MediaConvert job and then wait to get a response, so we are using Lambda here to process the response.
