The onscreen controls are designed to work in conjunction with the image that’s
displayed by the Preview and Broadcast displays. In other words, you use the onscreen
controls to isolate the portion of the image you want to output, and you view the
actual transformation on the Preview and Broadcast displays.
To resize a shot:
m Drag any of the four corners of the onscreen control to resize the shot relative to its
center.
The onscreen control shrinks or expands to include less or more of the image, and the
Preview and Broadcast displays show the result. This also adjusts the Scale parameter.
To rotate a shot:
m Drag just outside the four corner handles, right to rotate left, and left to rotate right.
Because the onscreen control works by selecting a portion of the static source image,
the onscreen control rotates in the opposite direction of the effect, but the Preview and
Broadcast displays show the correct result.
