Understanding Masking Feature In Alight Motion
Before learning how to do masking on Alight Motion, it is important to understand what masking actually means in video editing.
Masking is a technique that allows you to hide or reveal specific parts of a video or image layer. Instead of showing the entire layer, masking lets you display only the area you choose. Everything outside the mask becomes invisible.
For example, imagine you have a video of a person standing in a park. If you apply masking, you can show only the person and hide the background. You can also show only a small circular portion of the video while hiding the rest.

In Alight Motion, masking works by using shapes or layers as masks. The mask layer controls which part of the video will be visible. When you place a mask on top of another layer, it determines what will appear in the final video.
Masking is used for many creative purposes, such as:
- Highlighting objects in a video
- Creating cinematic reveal effects
- Making text appear behind objects
- Creating transitions between clips
- Adding focus effects to important elements
- Combining multiple clips creatively
One of the best things about masking in Alight Motion is that it works together with keyframes. This means the mask can move, resize, or animate over time. Because of this feature, editors can create dynamic effects such as tracking objects or revealing elements gradually.
For beginners, masking might look like a complex editing technique. But once you understand the basic idea — a mask simply hides or reveals part of a layer — everything becomes much easier.
Understanding this concept is the first step in mastering how to do masking on Alight Motion and creating professional video edits.
