Cropping, Positioning & Scaling
The Crop, Position & Scale effect allows you to accurately crop, position and scale a source. Changing any of the values can be done by entering the desired value (%), use the up/down buttons, or click and drag the Crop, Position or Scale buttons. An additional zoom function, which changes both the scale and position simultaneously, is available through the mouse scroll wheel. Hold down the Shift key to improve accuracy when using your mouse. To reset a value to its default double click it while holding down the Shift key.
Note cropping is not supported by the chroma keyer.
