CameraShake

Transformv1coreConcat: Xform

Overview

Shake the picture like a camera: pick a preset (Handheld, Walking, Running, Vehicle, Explosion hit, Earthquake) and turn intensity for how far and speed for how fast. hide_edges zooms in just enough that the frame's edge never shows, and motion blur is on. It is a Transform underneath, so it joins the Transforms around it in one resample. The viewer draws the shake's path over the range with a dot at this frame.

How to

How-to

Wire the plate (or the finished comp) into a CameraShake and pick a preset: Handheld, Walking, Running, Vehicle, Explosion hit, Earthquake or Subtle float.
Turn intensity for how far it moves (pixels) and speed for how fast (wobbles a second); roughness adds jitter, rotation and zoom add turn and breath.
hide_edges (on) zooms in just enough that the frame's edge never shows; motion blur is on, as a real shake has.
For impacts, list frames in hits (24, 60); hit_strength and hit_decay set how hard and how long they ring. start, end and ease limit when it shakes.
The viewer draws the shake's path over the range with a dot at this frame. It is a Transform underneath and joins the Transforms around it in one resample.

Parameters

Parameter	Type	Default	What it does
intensity	Float	8.0	How far the picture moves, in pixels. The shake reaches about this far at its peaks and rarely past it.
speed	Float	2.0	How fast it shakes: wobbles per second. 1 to 2 is a person holding the camera, 3 to 4 is running, 6 and up is an engine or a road.
roughness	Float	0.4	How jittery the motion is. 0 is a smooth, floating drift; 1 adds fine, fast jitter on top of the sway.
rotation	Float	0.3	How far the picture turns at its peaks, in degrees. Real handheld is usually under 1.
zoom	Float	0.0	How much the picture breathes in and out, in percent. 0 = no push.
horizontal	Float	1.0	How much of the shake is side to side (0 to 1). Lower it for a walk, whose bob is mostly vertical.
vertical	Float	1.0	How much of the shake is up and down (0 to 1).
seed	Int	1	Which shake: the same numbers with another seed give a different motion with the same character.
hide_edges	Bool	true	Zoom in just enough that the edge of the frame never shows, on any frame: worked out from how far the shake can move and turn, so the zoom is steady. Off shows the frame moving over black.
motionblur	Float	0.5	Motion blur from the shake's own movement, as on Transform: 0 = off, 1 = everyday quality. A shake without blur looks like a jittery overlay.
shutter	Float	0.5	How long the shutter stays open, in frames (0.5 = a 180 degree shutter).
shutter_offset	Choice	centred	Where the shutter sits around the frame: centred on it, starting at it, or ending at it. `centredstartend`
start	Int	1	The first frame that shakes. Before it the picture is still.
end	Int	0	The last frame that shakes; after it the picture is still. 0 (the default) shakes to the end of the shot.
ease	Float	0.0	Frames over which the shake grows in after start and dies out before end. 0 starts and stops at once.
hits	Text		Frames where a jolt hits, as a list: 24, 60, 112. Each kicks the picture a seeded way and rings down, on top of the steady shake: explosions, impacts, a door slam.
hit_strength	Float	3.0	How hard each hit kicks, as a multiple of intensity.
hit_decay	Float	12.0	How many frames a hit takes to ring down.
filter	Choice	cubic	How the picture is resampled as it moves: cubic keeps it sharp; bilinear is softer and a little faster. `impulsebilinearcubicmitchelllanczos`
fps	Float	24.0	The project's frame rate when the node was made: `speed` is per second. Set by Forged; hidden.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
