Resizing a Comp
When you use a preset to create a comp, you probably won’t go back to change any of its basic settings like the frame size, PAR, and frame rate. But it’s not unusual to change a comp with custom settings, particularly its frame size. For example, you might find that you created a comp that’s unnecessarily large, or too small to accommodate the layers that you need. If so, be sure to pay a visit to the Composition Settings dialog’s Advanced tab. When you resize a composition, the Advanced tab’s anchor setting determines how the layers are placed in the resized frame.
To set the anchor of a resized composition:
Select a composition and press Command-K (Ctrl-K) (Figure 4.7).
Figure 4.7 Before the composition is resized, it looks like this.
The Composition Settings dialog appears.
- To change the frame size of the composition, enter new values in the Width and Height fields.
Click the Advanced tab.
The Advanced settings pane of the Composition Settings dialog appears.
In the Anchor control, click one of the nine anchor point positions (Figure 4.8).
Figure 4.8 In the Advanced panel of the Composition Settings dialog, click one of the nine anchor positions.
Click OK to close the Composition Settings dialog.
The layers contained in the composition align to the position you specified (Figure 4.9).
