Motion blur effect with a real shutter
Turn on motion blur for a layer and set the shutter. AgentFX renders several sub-frame samples per frame and averages them, so blur follows curves, spins and bounces, not a straight smear.

"Make our logo whip in from the left with film-like motion blur, settle with a small overshoot, keep the tagline sharp. 16:9 and 9:16."
The agent writes the script, lints it, checks a contact sheet and renders every format. You give notes in plain words.
Parameters
mblur: sub-frame samples per frame (quality)shutter: shutter angle, 180deg is film-like, 360deg is smootherper layer: blur only what moves, leave type sharp

FAQ
Is it real motion blur or a directional blur filter?
Real: the renderer draws the layer at several moments inside the shutter and averages them, so rotation and curved paths blur correctly.
Does motion blur slow down rendering?
Yes, roughly by the number of samples for the blurred layers. Static layers are not re-rendered, and you can set fewer samples for previews.
