The Mask effect allows you to create an alpha or luma mask from any object to show only a specific area in a design. A mask changes the opacity of lower layers in the timeline to show the area inside of the mask's dimensions. You can also invert a mask and apply other effects to further customize your design.

- Open a Titler Pro project and do the following.
- Determine which area of the design you want to show or hide with a mask.
- Determine which layer you will convert to a mask. If necessary, insert a new object for this purpose.
- If necessary, in the timeline, move the layer that will become a mask so that it is above all layers that you want to affect with the mask.
- Select the layer that you want to convert to a mask.
- In Attributes > Object > Effects, select Mask from the Blending mode drop-down list. Notice all objects that are outside of the mask's dimensions are no longer visible.
- To apply additional effects to the mask, mark any of the following checkboxes in the Effects Settings section.
- Mask Single Layer Only: Affects only the layer immediately below the mask, but not any other layers below the mask.
- Mask Uses Luma: Creates an alpha result based on the mask’s luminance.
- Invert Mask: Inverts all transparent and opaque layers in relation to the mask.
- Preview Mask: Shows the shape of the mask and its affect on other layers in the preview window.
- Preview and save your design.
