Elastic Transcoder & Elemental MediaConvert

Amazon Elastic Transcoder is a media transcoding service that AWS introduced to help convert (transcode) media files β€” usually videos and audio β€” from their original format into different formats that can be played on various devices (smartphones, tablets, browsers, TVs, etc.).

πŸ”Ή What it does

Takes an input media file (e.g., MP4, MOV).

Converts it into multiple output formats (different resolutions, bitrates, codecs).

Makes it easy to stream or download on a wide range of devices.

For example:
You upload a 4K .mov file β†’ Elastic Transcoder can generate:

A 1080p MP4 for desktops.

A 720p MP4 for tablets.

A 480p MP4 for mobile streaming.

Audio-only output (e.g., AAC or MP3).

πŸ”Ή Key Features

Fully managed (no servers to manage).

Pay-as-you-go pricing.

Integrated with Amazon S3 (store source and destination files).

Presets for common devices and formats.

Can generate thumbnails and watermarks.

πŸ”Ή Current Status

⚠️ Important: Elastic Transcoder is a legacy service.
AWS now recommends using AWS Elemental MediaConvert, which is more powerful and supports modern streaming standards (HLS, DASH, DRM, 4K/8K, advanced codecs).

πŸ‘‰ So in short: Elastic Transcoder = old AWS video/audio conversion service, mainly replaced by MediaConvert today.

Amazon Elemental MediaConvert is an AWS service for video transcoding β€” basically converting video files into different formats so they can be played on different devices and platforms.


What it does

  • Takes a source video (like MP4, MOV, etc.) and converts it into different formats, resolutions, bitrates, and codecs.
  • Supports outputs for web, mobile, broadcast, and OTT (Over-the-Top) streaming.
  • Allows you to make videos that work on different devices and screen sizes.

Key features

  • File-based transcoding (not live streaming).
  • Supports a wide range of codecs (H.264, HEVC, MPEG-2, etc.).
  • Can produce adaptive bitrate outputs for streaming (HLS, DASH, CMAF).
  • Supports closed captions, DRM, audio normalization.
  • Works at scale with pay-per-use pricing.

How it’s used

  • A streaming company can upload a high-quality master video β†’ MediaConvert creates different versions for mobile, web, and TV streaming.
  • A media company can repackage content for different devices and formats.
  • An enterprise can transcode training videos for compatibility with various internal platforms.

πŸ’‘ Quick analogy:
If your raw video is like a loaf of bread, MediaConvert is the bakery that slices and packages it in different ways so everyone β€” whether they want a sandwich, toast, or croutons β€” can enjoy it.
