Tracker to Nuke

Overview

Tracker to Nuke is a Blender addon that allows you to easily transfer 2D tracking data from Blender’s Movie Clip Editor to Nuke via copy and paste.
It also supports copying and pasting lens distortion parameters in Nuke's default distortion model.

Features

• Copy Blender’s 2D tracking data directly to Nuke's Tracker Node via clipboard.
• Supports full tracker export, selected trackers, pattern corners, and plane tracks.
• Transfers lens distortion parameters between Blender and Nuke using Nuke’s default distortion model (K1, K2).

Location

• Movie Clip Editor
  • Sidebar > Track Tab > Tracker to Nuke
  • Header > Tracker to Nuke

Tracker Export

When you copy tracking data, it is formatted for direct pasting into Nuke as a Tracker Node.

• ALL
  Copies all trackers from the active Movie Clip to the clipboard.

• Selected
  Copies only the selected trackers from the active Movie Clip.

• Export Pattern Corners
  Copies the 4 corner positions of the selected track’s pattern area.

• Export Plane Track
  Copies the 4 corner positions of the selected Plane Track.

Note:

• Ensure that the footage starts on the same frame in both Nuke and Blender.
• After pasting into Nuke, you need to update the reference frame value to use the data properly. Tracker Node > Transform Tab > reference Frame
• If the clip contains multiple tracking objects, the markers from the active object will be copied.
• Blender's lens distortion correction is not applied to the coordinate transformation of 2D tracking data.

Lens Distortion

Allows lens distortion parameter exchange between Blender and Nuke’s default distortion model (K1, K2).

• Copy
  Copies the lens distortion parameters of the Nuke model in the active clip to the clipboard. The copied data can be pasted directly as a LensDistortion Node in Nuke.

• Paste

Select the LensDistortion Node in Nuke and copy it to the clipboard. Pastes lens distortion parameters from the clipboard into Blender. If the lens distortion model is not set to "Nuke" in Blender, it will be automatically switched.
