LensDistortion

Radial lens distortion

Adds or compensates simple radial barrel/pincushion distortion with channel splitting, center adjustment and configurable edge handling.

Overview

What LensDistortion does

Adds or compensates simple radial barrel/pincushion distortion with channel splitting, center adjustment and configurable edge handling.

LensDistortion bends the image around a configurable optical center. Positive and negative distortion move the image toward barrel or pincushion behavior, while edge modes decide how newly exposed borders are filled.

Mental model

LensDistortion bends the image around a configurable optical center. Positive and negative distortion move the image toward barrel or pincushion behavior, while edge modes decide how newly exposed borders are filled.

Common uses

Add barrel or pincushion distortion
Approximate a lens match for graphic inserts
Create stylized optical warps
Shift the optical center
Experiment with channel-separated distortion

Flow anatomy

Inputs & outputs

The port structure shows how this node fits into a Fusion graph.

Input

Source image for the operation.

Effect Mask

Optional mask that limits where the node affects the image.

LensDistortion
Fusion node

Output

The processed result from this node.

Inspector

Important parameters

Start with these controls before reaching for more complicated workarounds.

Split Channels

Allows separate distortion behavior for color channels.

Distortion

Controls the main radial bend.

Fine Adjustment

Provides smaller distortion corrections.

Position X

Sets the horizontal position or offset.

Position Y

Sets the vertical position or offset.

Edge Behaviour

Chooses Black, Reflect, Wrap-Around or Replicate for exposed boundaries.

Edge Behaviour: Black

Uses Black handling outside the image boundary.

Edge Behaviour: Reflect

Uses Reflect handling outside the image boundary.

Edge Behaviour: Wrap-Around

Uses Wrap-Around handling outside the image boundary.

Edge Behaviour: Replicate

Uses Replicate handling outside the image boundary.

Workflow: Distortion + Position

Sets Workflow to Distortion + Position.

Practical setup

A reliable workflow

  1. 1

    Place the optical center over the real lens center or intended effect center.

  2. 2

    Adjust Distortion in small increments.

  3. 3

    Use Fine Adjustment for matching rather than overdriving the main value.

  4. 4

    Choose an edge mode that will survive animation.

  5. 5

    Check straight architectural lines and frame borders.

Troubleshooting

Common mistakes

Applying LensDistortion before the image is in the technical state the node expects.
Pushing LensDistortion too far before checking artifacts at full resolution.
Judging LensDistortion on one still frame instead of checking motion and edge behavior.

Production notes

Practical tips

Compare LensDistortion with bypass regularly while tuning it.
Keep LensDistortion and other technical conversions separate from creative grading when possible.
After strong LensDistortion processing, check alpha, highlights and image boundaries.
