Masking is a process where a transparent shape layer is drawn/created over the main clip. When masking is done, any portion of the video that is covered with the mask is visible and everything else remains hidden.

Masks are mostly used to prevent the viewers from any distraction and draw their attention to a particular action or person.

Go to the Masks tab

Click the video clip in the timeline to enter the Video panel. Switch from Basic to Mask tab, and you will find some basic mask shapes, such as rectangle, circle, double line, single line, love and star. You can also draw a mask shape as you like.

Apply a Mask

You can apply an existing video mask or load your own video mask by clicking Import. Click one of the shapes from the Masks, you will see only the area covered with the mask shape is visible and everything else gets hidden in the Preview window.

Draw a mask

Using the Draw Mask feature, you can create complex masks in any shape by dragging control points and modifying B-Splines. You can zoom in and out on the player screen and draw the mask shape precisely. You can easily create smooth curves by holding the Alt/Option to adjust the Bessel curve for drawn masks. Also, you can save the draw mask as preset to apply it with one click.
