The Deskew filter could be used to straighten out an image when you are not able to place your camera exactly in front of the object. The best example is a score board in a gym: You want to put the score board into your video production but can’t bring the camera in a good position to capture it from the front. You apply the Deskew filter to the video source, move the 4 cross hairs to the corners of the scoreboard and you have a perfect straight view of it. Now you can put this video with a “Placer” layer anywhere on the screen.

Filter Setup Modes
Side by Side The original and the deskewed image are displayed side by side in order to show you the result of your settings immediately while you are dragging the crosshairs.
Original In this mode you have the full size of the original image so that you are able to position the cross hairs very accurately
Deskewed This mode shows you the result of the filter. You can check on the transparent areas and the correct alignment in detail.
Aspect Ratio Modes
Custom If the automatically calculated aspect ratio of the result is not correct, you can enter your own aspect ratio here. if the resulting image isn’t in the same aspect ratio than the original one then the resulting image is scaled “fit to screen” giving transparent areas around it.
Automatic mimoLive will calculate the aspect ratio of the deskewed area based on the positions of the cross hairs. This may fail if the perspective is to extreme.
