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
