ABR Rendition Ladder

video-renditions

Specifies a custom adaptive bitrate (ABR) rendition ladder for HLS and DASH output.

video-renditions accepts a string that defines the set of quality levels included in the adaptive manifest. When not specified, Imgix generates a default rendition ladder based on the source video’s resolution and bitrate.

This parameter applies only when fm=hls or fm=dash is set.

Use video-renditions to precisely control which resolutions and bitrates are offered to players, which is useful for:

  • Meeting specific platform or CDN requirements
  • Reducing origin egress by limiting the number of renditions
  • Tailoring the ladder for a known target device range
