Using Filters to Ease Tracking

Use a filter to make the reference feature(s) easier to track. Once the tracking is complete with your "good" tracking data, you remove the filter.

For example, if the reference feature does not have enough contrast, you might use the Color Corrector to increase the contrast. Or you might apply an emboss effect.

For more information on applying effects, see Applying Operators.

To use filters before tracking in a Paint operator:

1. Choose Selection | Select Entire Image.
2. Choose a filter from the Effects menu.

The filter is applied to the clip.

3. Select the target object (the object that should "follow" the tracked motion).
4. In the Tracker panel, click Position, Scale, or Rotation, depending on the type of motion you want to track.
5. Position the Tracker(s) in the viewport.
6. Select Clip + Objects from the Source list.
7. Adjust the Tracker settings as required, and then click the Analyze button.
8. When the tracking is complete, turn off the Tracker, and remove or turn off the effect.

To use filters before tracking in a Composite operator:

1. In the Workspace panel, select the source layer (the layer that contains the motion you want to track).
2. Choose a filter from the Operators menu.

The filter is applied to the selected layer.

3. Select the target layer (the layer that should "follow" the tracked motion).
4. In the Tracker panel, select the source layer from the Source list.
5. Click Position, Scale, or Rotation, depending on the type of motion you want to track.
6. In the Tracker panel, adjust the Tracker settings as required, and then click the Analyze button.
7. When the tracking is complete, turn off the Tracker, and remove or turn off the operator that you added in step 2.
