Saving or recalling a keyframe preset
Keyframe presets save the settings of the selected keyframe row at the cursor position.
Presets for 2D and 3D track motion are saved separately: presets you create in this window will not be
available in the 2D Track Motion window.
Saving a preset
1. Adjust your Position settings as desired to create a keyframe.
2. Type a name in the Preset box.
3.
Click the Save Preset button .
Recalling a preset
1. Click in the keyframe controller to position the cursor where you want to apply the preset.
2. Choose a setting from the Preset drop-down list.
If no keyframe exists at the cursor position, one is created using the settings from the preset. If a
keyframe exists at the cursor position, the keyframe's settings are replaced with the settings from the
preset.
Deleting a preset
Click the Delete Preset button to delete the current preset.
Examples of various 3D compositing scenarios
In the following examples, track two (blue-and-yellow checkerboard) is rotated forward in 3D space, track
4 (green-and-gray checkerboard) is rotated backward in 3D space, and track 3 (red-and-white
checkerboard) is a 2D track.
Track 1 is used to rotate tracks 2 through 4 so you can see the compositing interaction.
In the first example, the 2D track is a compositing child to track 2. The 2d child is inserted in the
composited output at a depth of zero on the Z axis, and tracks 2 and 4 intersect in 3D space.
