You can make advanced adjustments to your settings with the Geometry pane of the
Inspector window.

Working with Cropping, Scaling, and Padding
The Geometry pane provides three different methods you can use to affect the output
image.
Cropping
When you crop an image, you are removing video content. Often that content is
unnecessary image area (such as the overscan area, which is necessary for television, but
not for computers) to make what’s left seem bigger in the same frame size.
Cropping also includes an automatic setting that detects image edges and automatically
enters crop values to match them. This is especially useful if you want to crop out the
letterbox area of a source media file.
When you adjust the crop settings, one of two things happens to the output video file’s
frame size:
• The frame size remains the same if you have chosen anything other than the 100% of
source, 50% of source, and 25% of source settings in the Frame Size pop-up menu of
the Dimensions section of the Geometry pane. This means that the source video image
is scaled larger to fill the output video file’s frame size, which results in larger pixels
and overall image degradation.
• The frame size reduces by the crop amounts if you have chosen the 100% of source,
50% of source, or 25% of source settings in the Frame Size pop-up menu of the
Dimensions section of the Geometry pane. This can result in nonstandard frame sizes.
