Overview
Computes optical-flow motion vectors between frames, for VectorBlur and retiming.
How to
How-to
- Wire the sequence; the node computes optical flow between frames, scaled by
scale. - Feed the vectors into VectorBlur or a retime.

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| reference | Float | 1.0 | Which neighbouring frame the motion is measured against: +1 = the next frame, −1 = the previous. |
| 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. |
| scale | Float | 1.0 | Multiply the vectors before publishing — match another renderer's convention. |
| 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). |
