If your DVD videos are upside down or your videos have something wrong with visual effect, you can use this function to make them corrected.
Click at "Edit" button on the main interface of TuneFab DVD Ripper. Then you will see the below interface. There are 4 ways to rotate a video: Rotate 90 clockwise, Rotate 90 counterclockwise, Horizontal flip and Vertical flip.
Select the way you like to rotate the video. And you can preview the effect directly via this program before converting. If everything goes well, you can click at "Apply" to save the changes.
