Overview
Blurs along motion vectors — real per-pixel motion blur from a MotionVectors pass or a renderer's vectors.
How to
How-to
- Wire the image and a motion-vector pass (or a MotionVectors); set
shutter_offset. - Real per-pixel motion blur from the renderer's own vectors.
Inputs
| Input | What it takes |
|---|---|
| in | the image this node works on |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |
Outputs

| out | Image |
Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| channels | Choice | rgba | Which channels this node writes: rgba, rgb (alpha passes through untouched), alpha only, all, or none (bypass). Everything unselected comes straight from the input — same as Nuke. allrgbargbalphanone |
| shutter | Float | 0.5 | Shutter time as a fraction of a frame: 0.5 = 180°. How long the blur smears. |
| shutter_offset | Float | 0.0 | Shift the shutter interval, in frames: negative starts it before the frame. |
| samples | Int | 9 | How many sub-steps the effect integrates over. More is smoother and slower. |
| levels | Int | 4 | Pyramid depth of the motion solve. Each level doubles the motion that can be found; more than the frame has is noise. |
| window | Int | 3 | Half-width of the motion solver's matching window. Larger is more robust and less local. |
| iterations | Int | 4 | Refinement passes per pyramid level of the motion solve. |
| reference | Float | 1.0 | Which neighbouring frame the motion is measured against: +1 = the next frame, −1 = the previous. |
| 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). |
