The
Sizing Adjust Submenu
lets you:
•
Scale the selected input video up (or down) within the current active area.
•
Mask (crop) an image, either one edge at a time, or by using preset masks of all
four edges to achieve a specific aspect ratio.
As you adjust sizing, the top and bottom portions of an image may fall outside of the raster,
for example, when a 4:3 image is scaled up to 16:9.
