Working with the Pan & Scan Tab
You can transform shots in your program using two sets of controls. To the left,
onscreen controls appear within the image preview area, while to the right, numeric
parameters mirror these adjustments.
Using the Onscreen Controls
The onscreen controls for the Pan & Scan tab consist of an outer bounding box that
represents the scaled output with four handles at each corner, and a pair of action and
title safe indicators within. By default, the onscreen control is the same size as the
resolution of your project.
