You can find the Dynamic mask effect in the Toolbox below the tab Objects in the section Live effects.

A mask defines the area of ​​your image that is visible or invisible in the presentation. This means that the mask can take any form and be of any size. It further means that a text, an image, videos, Flexi-Collages as well as a chapter can be a mask. The mask effect is dynamic. This means that the masked area can be animated and can thus change the flow of the presentation.

Example: Everything that is black and white can be a mask - also pictures in shades of gray are masks. The Dynamic mask effect ensures that the image, which is located in a track above the mask can be seen within the field, where the mask is white. The rest is covered by the mask.

•Content: Here you add the objects on which you want the mask to have an effect.

•Mask: You insert the mask here. For this you can use ready-made graphics from the Toolbox, which you can find under the tab Objects tab in the Masks section.
