Hi,
In Debut, you can use the option Flip under the Effects tab to flip the video left-right or top-bottom. You can also edit your video in VideoPad. All you have to do is to upload the video file in VideoPad > Place the file on the Timeline > Right-click on the video file > Rotate clip > Choose one of the following options: 0 degrees, 90degrees, 180degrees, 270 degrees.
