Specifying the Default Spatial Interpolation
Ordinarily, motion-path keyframes use auto Bézier interpolation. If most of your spatial animation requires linear interpolation (or if you simply prefer it as your initial setting), you can change the default in the Preferences dialog.
To set the default spatial interpolation:
- Choose After Effects > Preferences > General (Edit > Preferences > General) (Figure 9.20).
- Do either of the following (Figure 9.21):
- Click the Default Spatial Interpolation to Linear check box to make new motion paths use linear interpolation.
- Leave Default Spatial Interpolation to Linear unselected to make new motion paths use auto Bézier interpolation.
- Click OK to close the Preferences dialog.
The General pane of the Preferences dialog appears.
Figure 9.20 Choose After Effects > Preferences > General on the Mac, as shown here (or Edit > Preferences > General in Windows).
Figure 9.21 In the General pane of the Preferences dialog, choose whether to use linear interpolation as the default.
