Scale Effect (Scale Effect) multiplies the video size by the Target value (larger or smaller than 1) relative to the natural recorded size of the video. You can scale 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.
Scaling expands (or contracts) 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 scaled. Cyan rectangle is the image original size. Light blue rectangle is the image scaled by a factor of 2 (both X ans Y). Arrows show the direction of size expansion.
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 (Scale, rotation, etc).
This example shows a before and after size of a Screen when we set Scale Targets to X=0.5, Y=0.5 (Figure 3). The Screen rectangle sides are reduced by 50% (Screen on the righthand side).
