dynamic_range #

The video-capture dynamic-range enum.

DynamicRange #

Bases: Enum

A video capture's dynamic range, shared by every video node.

  • SDR — standard dynamic range (default).
  • HDR — the richest HDR the capturing pipeline offers: 10-bit HLG/BT.2020 on the device-camera video nodes; exposure fusion within the unchanged 8-bit BT.709 feed on the ARKit posed nodes (ARKit has no 10-bit format). Best-effort, like every capture preference: a device or format without HDR records SDR rather than failing the capture.
