The built-in effects buttons below the Viewer.
The buttons beside the Show icon act just like the buttons beneath the Viewer and activate the on-screen con-
trols. Once the parameters are uncovered, you can alter the image using the sliders and dials or by typing in a
value directly into the Settings field. Clicking the curved arrow button resets any changed settings to their de-
fault values, and you can temporarily turn off any effect by clicking the blue box next to the effect's name. Let's
look at how each of these effects works.
Transforming images
The first effect that we're going to look at is Transform, which allows you to change the position, rotation, and
scale of an image. To bring up the on-screen Transform controls, select a clip in the Timeline and either click on
the first button on the left below the Viewer or press Shift+T. This superimposes eight blue dots around the im-
age in the Viewer, which can be used to alter the image in several ways:
• Clicking and dragging on any of the four corner dots allows you to scale the image up or down, while
maintaining the image's aspect ratio (the relationship between the width and height). Holding down the
Shift key as you drag lets you contort the aspect ratio in many ways.
• Clicking and dragging any of the four side dots shrinks or enlarges the image. Holding down the Shift key
as you drag maintains the image's aspect ratio, while holding down the Option key allows you to affect just
the side that you're dragging.
• Clicking and dragging inside the image allows you to move the image and position it anywhere on the
screen.
• Clicking and dragging on the center handle let you rotate the image (see Figure 14.2). Moving the handle
farther away from the center allows you to make finer and more precise adjustments. Holding the Shift key
as you rotate constrains the rotations to 45-degree increments.
