5 Adjust render range: In the Keyframes Editor, adjust the render range to match the
range of frames where the planar surface is visible.
6 Adjust track options: Frequently changed options include Tracker, Motion Type, and
Track Channel.
7 Mask out occluders: If moving objects partially cover up the planar surface, you may
wish to connect an occlusion mask to the Planar Tracker. When using the Hybrid
tracker, providing a mask to deal with occluding objects is strongly recommended,
while with the Point tracker it is recommended to try tracking without a mask.
8 Track: Click the Go button to return to the reference frame. Press the Track To End
button and wait for the track to complete. Click the Go button to return to the reference
frame again. Press the Track To Start button and wait for the track to complete.
Note that the tracks in the viewer are not selectable or deletable as they are in a
Camera Tracker.
9 Check track quality: Visually inspect the track to see how accurate it is. Does it stick to
the surface? Switching to Steady mode can help here.
10 Use the track: At this point, in most cases you will create a Planar Transform node
from the Inspector and use it to apply the tracked perspective distortion onto masked
images. If the image you are applying the tracking data to is full frame unmasked
clip, you can use the Steady, Corner Pin, and Stabilize operation modes in in the
Planar Tracker.
Inspector
Controls Tab

the reference frame and initiating the track.
Operation Mode

has four modes of operation:
 Track: Used to isolate a planar surface and track its movement over time. Then, you
can create a Planar Transform node that uses this data to match move another clip in
various ways.
