Planar track
Last updated
Planar track is a Utility effect.
What it does
Section titled “What it does”Follows a flat surface, or one or two points, through a shot, and writes the movement onto another layer as a Corner pin or as transform keys.
Where what is being followed stops being followable, the analysis stops there and keeps the part that worked.

What each control does
Section titled “What each control does”- Analyse: start tracking.
- Cancel: stop a track that is running.
- Create corner pin: put a keyframed Corner pin on the layer named below.
- Create transform keys: keyframe that layer’s own Position, Rotation and Scale to the movement instead. The keys are added to what the layer already had. Following one point writes Position alone.
- Follow: a flat surface as four corners, one point, or two points followed separately. Two points need not be on one surface.
- Upper left, Upper right, Lower left and Lower right: the four corners of the surface. Read when Follow is Surface.
- Point 1 and Point 2: the points to follow. Read when Follow is one of the point options; Point 2 only for Two points.
- Region size: how wide each point’s search box is.
- Pin layer: which layer the Corner pin, or the transform keys, are put on.
- Feature density: how many specks the tracker chases. More is slower but copes better with a plain or badly lit surface.
- Use masks: masks on the layer are left out of the track.
