scale the output files to use square pixels and maintain the
original aspect ratio (which results in an increase or decrease
in the number of horizontal and vertical pixels).
Cropping and padding
Customize the final cropping, sizing, and using the
Cropping & Padding properties. Cropping removes video content
from an image. Padding scales the image to a smaller size while
retaining the output image’s frame size. For more information
about these properties, see .
Cropping: This pop-up menu sets the dimension of the output
image. The custom option allows you to enter your own image
dimensions in the fields; other options use predetermined
sizes. The Letterbox Area of Source option detects image
edges and automatically enters crop values to match them.
This is useful if you want to crop out the letterbox area (the
black bars above and below a widescreen image) of a source
media file.
