Lens Distortion

Indicates a feature suggested and voted up by users on the Flame Feedback portal.

Use the Lens Distortion node to compute the lens distortion of a clip, employing either a Lens Grid clip or manually-inserted splines. The result of the calculation can be employed to either undistort or distort the clip.

Note: This new Lens Distortion node replaces the old Lens Distort node which is now a legacy node and is hidden by default. Setups from previous versions that you restore in 2025 will be restored with the legacy Lens Distort.

Highlights include:

Import 3DEqualizer Lens Distortion data.
Selection of multiple distortion models.
Automatic detection of lines in a Lens Grid or Front clip.
Selection of the repeat mode.
Selection of the filtering, including the new Mitchell-Netravali and Catmull-Rom filters.
Output of an STMap and Inverse STMap to apply the same undistortion to other clips or to apply back the distortion using the STMap node.
Easy workflow to apply back the distortion with a duplicated Lens Distortion node.
