The "Crop" feature of TuneFab DVD Ripper makes it easy for users to get a video without black bars or unwanted edges.
On the main screen of TuneFab DVD Ripper, click at "Edit" button and you will see this pop-up interface.
On the right side of the interface, go to "Crop Area Size" to manually enter the area size you like. Or you can drag and adjust the cropping frame directly to make sure that the parts you don't want are outside of it.
When all is set, click at "Apply" to save the changes.
