Elastic Transcoder and AWS Elemental MediaConvert

  • MediaConvert a fairly new AWS product replacing Elastic Transcoder
  • MediaConvert is a superset of features provided by Transcoder
  • Both of the systems are file based video transcoding systems
  • They are serverless transcoding services for which we pay per use
  • For both we add jobs to pipelines (ET) or queues (MC)
  • Files are loaded from S3, processed and stored back to S3
  • MC supports EventBridge for job signalling
  • ET/MC architecture example: ET/MC architecture
  • We use these products when we need to the media convert in a serverless, event-driven media processing pipeline

Choosing between ET and MC

  • ET is legacy, by default we should chose MC
  • MC supports more codecs, design for larger volume and parallel processing
  • MC supports reserved pricing
  • ET required for WebM(VP8/VP9), animated GIF, MP3, Vorbis and WAV. All of these codecs are supported for MC. For everything else we should use MediaConvert
