Channel Types - Amazon IVS

Channel Types

There are four channel types: STANDARD, ADVANCED_SD, ADVANCED_HD, and BASIC. When you create a channel, the default type is STANDARD.

Depending on the channel type, video may be transcoded or transmuxed:

  • Video on STANDARD and ADVANCED channels is transcoded: multiple qualities are generated from the original input, to automatically give viewers the best experience for their devices and network conditions. Transcoding allows higher playback quality across a range of download speeds.

  • Video on BASIC channels is transmuxed: Amazon IVS delivers the original input to viewers.

All transcoded channels have transcode presets, which determine which renditions are produced. Think of these as ABR ladders. They allow you to trade off available download bandwidth and video quality, to optimize the viewing experience.

  • STANDARD channels have one, default transcode preset.

  • ADVANCED channels have two, selectable transcode presets:

    • Constrained bandwidth delivery uses a lower bitrate than STANDARD for each quality level. Use it if you have low download bandwidth and/or simple video content (e.g., talking heads).

    • Higher bandwidth delivery uses a higher bitrate for each quality level. Use it if you have high download bandwidth and/or complex video content (e.g., flashes and quick scene changes). This is the default.

STANDARD Channels

STANDARD channels are transcoded. The highest video resolution produced is full HD, 1080p. This is the default channel type.

  • Transcode presets: There is one, default transcode-preset ladder.

  • Audio: For renditions 360p and below, audio is transcoded. For other renditions: original audio is passed through.
