Transforming your clip

• (X, Y) Scale Use these controls to make your clip smaller or larger.

Full-screen size is represented as 100%. You can shrink your clip to 0% or

enlarge it to 1000%. Note, however, that by enlarging your clip, the

resolution may become blurry. You can adjust the size controls individually,

or if you select

Fixed Aspect Ratio, you only need to adjust the x axis.

Adjusting the percentage on the x and y axes changes your clip’s width and

height, respectively.

¦NoteSome effects, like Matrox surface finish, include a Z Scale property

that allows you to adjust the depth of the effect.

•

(X, Y, Z) Rotation Use these controls to set the number of times the clip

spins. Each rotation of 360° produces one spin on the selected axis. You can

have positive or negative rotation from -360° to 360°.

•

(X, Y, Z) Rotation Center Offset Use the Rotation Center Offset

controls to set the pivot point, or center of rotation, of your clip on the x

(horizontal), y (vertical), and z (depth) axes. When

Rotation settings are

applied, your clip spins around this point. You can use positive or negative

pixel values to offset your clip on each axis.

In the illustrations below, notice how different

Offset values can affect the

rotation of the cube.

In Figure 1, the

Offset values are (0,0,0), so the center of rotation for the cube is

where the x, y, and z axes meet. In Figure 2, the

Offset value for the x axis is set

to 100, thus moving the cube and the pivot point to the right, so when the cube is

rotated, it has a wider arc when spinning around the axes.

Figure 1: Offset at 0,0,0

Figure 2: Offset at 100,0,0
