Shutter angle calculator
open time = (shutter angle ÷ 360) × (1 ÷ frame rate). Nuke shutter = 0.5 is a 180° shutter.

Shutter angle

Shutter phase
Where the open window sits relative to the frame sample. Default is center (most CG / Nuke).

Cyan = open sector (light hits the film/sensor). Dark = closed. One full spin per frame.

Motion blur preview
~17 px · 8 samples
Multi-sample integration: 8 time samples along the path while the shutter is open (open time × speed). Same idea as multi-sample motion blur in a renderer — not a CSS blur filter.
