Plane Track Deform Node


Plane Track Deform Node.

The Plane Track Deform Node is used to incorporate the special “plane track” in your composite by checking areas which are planes, and replacing their footage with some other image.

Plane Track

Before using this node, plane track for the footage should be made in the Movie Clip Editor.


Image to put in place of the plane track, and thus, override that area in the movie clip.


Movie Clip
Used to select the movie clip whose plane track to use. For controls see Data-Block Menu.
Used to select the object to which the plane track is linked.
Used to select the plane track to use.
Motion Blur

Specify whether to use blur caused by motion of the plane track or not.


Set the number of samples to take for each frame. The higher this number, the smoother the blur effect, but the longer the render, as each virtual intermediate frame has to be rendered.


Samples are taken only from the next frame, not the previous one. Therefore the blurred object will appear to be slightly ahead of how it would look without motion blur.

Time (in frames) the shutter is open. If you are rendering at 24 fps, and the Shutter is set to 0.5, the time in between frames is 41.67 ms, so the shutter is open for half that, 20.83 ms.

Produces a black and white mask of the plane track.


Using Image Output

This can simply be achieved by using the alpha over node.

Using Plane Output

This can be achieved by mixing the movie clip and the image using the plane output as the factor.

Using Image Output vs Using Original Image

Using Image output scales, translates and skews the input image according to the track while using the original image and mixing it with the movie clip using Plane output as factor will display the part of the image that lies inside that mask. This image shows the difference:
