How do I add a mask in a video?

To add a mask to a video, you need to select the clip you wish to modify on the timeline and then begin drawing the mask directly onto the viewer. This process will immediately create a cutout in your footage.

Steps to Add a Mask

Here's a simple breakdown based on the reference material provided:

1. Select the Clip: First, identify and select the video clip on the timeline to which you want to apply the mask. This is the footage that you wish to modify.
2. Draw the Mask: Once the clip is selected, start drawing directly on the video preview area. This area is sometimes referred to as the "viewer".
3. Mask Creation: As you draw, the program will immediately create a cutout, forming the mask according to your drawing. Anything inside your drawing will be the visible part of the video.

This masking technique allows you to isolate specific parts of a video clip. The reference video shows this process beginning at the [0:10] mark and continuing through the [0:56] mark, demonstrating the drawing process.
