Tracker to Nuke earns a spot in the Blender extensions library for a focused job: moving 2D tracking data and lens distortion parameters from Blender's Movie Clip Editor into Nuke over the clipboard. It handles full trackers, selected trackers, pattern corners, and plane tracks, and its 1.1.0 update adds P1 and P2 anamorphic coefficients for Blender 5.1 and later.
Tracker to Nuke is a Blender addon from K_Naoki that moves 2D tracking data from Blender's Movie Clip Editor into Nuke through copy and paste. When you copy tracking data, it is formatted for direct pasting into Nuke as a Tracker Node, so the transfer runs over the clipboard.
The addon copies all trackers from the active Movie Clip, or only the selected trackers, and can export the four corner positions of a selected track's pattern area or a selected Plane Track. It also exchanges lens distortion parameters between Blender and Nuke using Nuke's default distortion model with K1 and K2 values, pasting them as a LensDistortion Node. If Blender's distortion model is not set to Nuke, it switches automatically. Note that footage should start on the same frame in both applications, and the reference frame value needs updating after pasting.
Version 1.1.0 adds support for Nuke's anamorphic coefficients P1 and P2 on Blender 5.1 and later. The addon is compatible with Blender 4.2 LTS and newer and is released under the GPL v3.0 or later.
Tracker to Nuke is best for artists moving 2D tracking data and Nuke-model lens distortion parameters from Blender's Movie Clip Editor into Nuke.
Tracker to Nuke is completely free to download and use.
Tracker to Nuke is compatible with Blender 4.2 LTS and newer, so recent Blender releases can run the addon. Its lens distortion exchange uses Nuke's default distortion model with K1 and K2 values across supported versions. From Blender 5.1 onward, the addon also passes Nuke's anamorphic coefficients P1 and P2, while versions prior to Blender 5.1 support only the standard K1 and K2 values. For the exact list of supported builds, check the developer's page before installing.
Tracker to Nuke lives in Blender's Movie Clip Editor. You can reach it from the sidebar under the Track tab, where it appears as Tracker to Nuke, and it is also available from the header as Tracker to Nuke. From there you copy tracking data formatted for direct pasting into Nuke as a Tracker Node. Note that the footage should start on the same frame in both Nuke and Blender, and after pasting you need to update the reference frame value under the Tracker Node's Transform tab to use the data properly.
Tracker to Nuke supports several export options from the active Movie Clip. It can copy all trackers to the clipboard, copy only the selected trackers, export the four corner positions of a selected track's pattern area, and export the four corner positions of a selected Plane Track. The copied data is formatted for direct pasting into Nuke as a Tracker Node. If the clip contains multiple tracking objects, the markers from the active object are copied. Blender's lens distortion correction is not applied to the coordinate transformation of the 2D tracking data.
Tracker to Nuke transfers lens distortion parameters between Blender and Nuke using Nuke's default distortion model, covering the K1 and K2 values. Copying sends the Nuke model's parameters from the active clip to the clipboard, which can be pasted directly as a LensDistortion Node in Nuke. Pasting works the other way: select the LensDistortion Node in Nuke, copy it, and Tracker to Nuke brings the parameters into Blender. If the distortion model in Blender is not set to Nuke, the addon switches it automatically. Blender 5.1 and later also handle the anamorphic coefficients P1 and P2.
Tracker to Nuke is listed as free here in the catalog and is released under the GNU General Public License v3.0 or later. For current licensing terms, source code, and any details on redistribution, check the developer's page on GitHub. The addon does not require special permissions, and its download size is small. Installation follows Blender's standard route, either by dragging the addon into Blender or downloading it and installing from disk.
