Skew Effect

Overview

The Skew Effect () bends the sides of the video at an angle (in degrees), keeping the sides parallel. Skewing animation begins at the From angle and continues to the To angle (see Figure 2.). Check the Apply a From Value checkbox to use the From value. If a From is not applied, skewing will begin at the current Skew angle.

You can Skew along either the X or Y axis or both. Using different values for Target Values X and Y will have the affect of stretching or squashing the image.

Give the effect a short Name that will identify its purpose or values.

See the Timing section for details on timing the animation of the effect.

See the Motion Behavior section for details on modifying the default behavior of the effect.

Target Values

• Valid Range  -360.0 to +360.0 degrees
• Unique Behavior  - Negative X or Y values will reverse the direction of the bending.

Origin Point

Skew bends the image along each axis from the Origin Point. An Origin Point centered on the image (X,Y = 0.5,0.5) is generally the best choice. See the Origin Point section for details the values.

In Figure 1, Origin Points (red dots based on X,Y values below the diagram) affect the way the image is Skewed. Black outlined rectangle is the image original shape. The cyan rectangle is the image Skewed by the X angle of 30 degrees. Note the skew direction with respect to different origin points. Skewing on the Y angle will have a similar effect.

Favorite Values

As a productivity aid, you can save the entire effect (all values on all tabs) as a Favorite with the Save as Favorite Values button. Then you can set all values of an effect from the Favorite values using the Set from Favorite Values button. Separate favorites are saved for each type of effect (Skew, rotation, etc).

Skew Example

This example shows a video Skewed in both X and Y directions by 15 degrees.
