How to use the Camera Tracker: Explained
Once your footage is uploaded to your timeline, and you're ready to start tracking, navigate to the top of After Effects and click the Window menu. Then, scroll down, and click Tracker.
Tracking Footage in After Effects
There are four tracking options that available in the tracker window that appears when you click Tracker in the After Effects Window menu:
- Track Camera
- Warp Stabilizer
- Track Motion
- Stabilize Motion
Once you click Track Camera, the 3D Camera Tracker effects will be added to your previously selected layer, and After Effects will begin analyzing this layer, counting the percentage of the clip tracked and total number of tracked frames.
Please note: little dots will appear across your footage; these are strictly referential and will not be rendered out.
For a visual guide, check the Render Track Points box in the 3D Camera Tracker effects menu.
Setting a Tracked Floor Plane in After Effects
Once your footage is analyzed, you'll need to establish: the tracking points; and the plane to which they should be tracked.
To begin, hover your mouse over the tracking point references in the composition window. A triangle will form between the three tracking points you're referencing, and a red 'target' will appear to help you visualize the plane.
The goal is to find tracking points that lay the red target parallel to the plane to which you're tracking.
To set the plane, left-click the triangle that lines up best for your surface. Once you move your arrow away, the picker should disable and the red 'target' will stop moving.
Adding Text to Tracked Footage in After Effects
Once your plane is defined, you can add text to your footage.
Hover over the recently set triangle and right-click the mouse. A window will appear with several options for creating new layers
To place text on your tracked footage, click Create Text.
After Effects will use the tracking data to place a new text layer in the scene, but you'll still need to align it.
Aligning Text on Tracked Footage in After Effects
To align your text layer to your tracked footage, find the tracked text layer in the timeline and click the arrow to the left. This will reveal all of the editable properties for the layer. Next click Transform to reveal the all the transform options.
Now you can adjust the X, Y and Scale values until the layer lines up.
To expedite your workflow, select your layer and press:
- S for scale
- P for position
- R for rotation
If you want to use more than one transform property, select your first one and then press and hold shift when selecting any additional properties.
