Cine camera parameter guide

The development Cine camera path keeps the camera at one fixed transform while exposing Unreal’s physical filmback, lens, focus, crop, clipping, and exposure controls. The open-source command contract is documented in Cinematic Camera Controls; this page adds parameter-oriented examples for the UnrealZoo development build.

Always record a short warm-up after changing a physical setting. Temporal history, auto exposure, and Lumen need a few rendered frames before a capture is representative.

Lens and filmback

The following panels use the same camera location and rotation. Changing focal length changes framing; changing filmback changes the field of view without moving the camera. Aperture changes depth of field while preserving the camera transform.

Same-position Cine camera comparison for focal length, filmback, and aperture

Focus and exposure

Manual focus is expressed in centimeters. ISO and shutter reciprocal are physical exposure controls; keep the scene and camera fixed when comparing values so the change is attributable to the parameter.

Same-position Cine camera comparison for focus distance and exposure

Reproduce the comparisons with commands such as:

vset /camera/0/cine/enabled 1
vset /camera/0/cine/lens 35 2.8
vset /camera/0/cine/focus 250
vset /camera/0/cine/exposure 100 60 1
vget /camera/0/cine/intrinsics

Crop, overscan, and near clipping are covered by the command table in Cinematic Camera Controls.
