Skew Effect (Skew Effect) bends the sides of the video at an angle (in degrees), keeping the sides parallel. 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. There are From and To values for both Horizontal and Vertical directions.
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.
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).
This example shows a video Skewed in both X and Y directions by 15 degrees.
