In this tutorial, an output mask will be created for a defined setup with a video projector. An image editing program (e.g. Photoshop / Gimp) must be used here.

- A - The selected video is loaded into the 'Preload' and active in the Layermanager.
- B - Go to the 'Bitmap' Submenu in the Keystone Tab.
- C - Select 'Crosshair' in the 'Brush' settings. The size of the Crosshair can be adjusted in the Brush Size settings.
- D - Specific selected points can be marked with Crosshair.
- E - With 'Export to Picture' the resulting graphic can be exported as an image.
- F - The graphic is stored as .png file on the desktop for the next step - processing into a mask in an image editor.
Tooltip: Masked outputs are an extremely effective tool for difficult projection projects.

Of course, masks can also contain color values and gray values. The mask is multiplied on the final output.

- G - The finished mask is opened again after it is saved. Select 'Import from Picture' to load the mask.
- H - The mask is now active in the output window.


Tooltip: PNG is used as a storage format as it contains alpha information and is lossless. The mask is exactly the same size as the display for the output window.
