Masking Feature in Alight Motion – Powerful Ways to Do Masking
Masking is a powerful video editing technique that allows creators to control which parts of a video, image, or text remain visible on screen while hiding the rest. In Alight Motion, the Masking Feature provides fine-grained control over media layers, helping editors create smooth reveals, professional transitions, dynamic animations, and visually focused effects.
This complete guide explains how to use the Masking Feature step by step, making it easy for beginners to learn while also sharing useful techniques for advanced editors. By mastering the Masking Feature, creators can achieve polished, high-quality results that truly take their videos to the next level.
What Is Masking in Alight Motion?
Masking is a technique used to hide or reveal specific areas of a layer. A Masking Feature works like a cut-out shape placed on top of a video, image, or text. Everything inside the mask remains visible, while everything outside the mask becomes invisible.
In Alight Motion, the Masking Feature is non-destructive. This means your original media is never permanently altered. You can adjust, animate, or remove the Masking Feature at any time, making masking ideal for experimentation and professional workflows.
Masks are commonly used to:
Why the Masking Feature Is Important
Masking is important because the Masking Feature adds precision and control to video editing. Instead of overwhelming viewers with full-frame effects, the Masking Feature allows you to guide their attention intentionally, helping you highlight exactly what matters on screen.

Some key benefits of masking include:
Without masking, many advanced motion graphics techniques would either be impossible or look messy and unpolished.
Understanding How Masks Work
Masks work by creating closed shapes that define “inside” and “outside” areas. The inside of the shape stays visible, while the outside is hidden. These shapes can be simple or complex, depending on your needs.
In Alight Motion, mask shapes can be:
You can also use multiple masks on a single layer to create more advanced visibility effects.
Types of Masks in Alight Motion
Alight Motion offers different mask types to suit various creative situations. Choosing the right mask type depends on the complexity of your project.
Rectangle Masks
Rectangle masks are the most basic and commonly used type. They are ideal for masking simple areas and geometric shapes.
Pros:
Cons:
Oval Masks and Other Shapes
Oval and circular masks are great for highlighting focal points and creating subtle vignette effects.
Pros:
Cons:
Pen Tool (Freehand) Masks
The Pen tool allows you to draw custom mask shapes using Bezier curves. This is the most powerful but also the most advanced option.
Pros:
Cons:
Using a combination of mask types often produces the best results, especially for advanced projects.
How to Do Masking in Alight Motion (Step-by-Step)
Add Media
Creating masks in Alight Motion is straightforward once you understand the process. Simply import a photo, video clip, or graphic you want to use for masking, then tap the layer to select it before adding a mask.
Open Mask Tools
Tap the “Masks” icon in the toolbar to open the masking tools, or tap the “+” button on your selected layer and choose “Mask.” You can also tap the layer to open the editing panel, where the masking option gives you access to all available mask tools.
Choose a Mask Type
Select the mask type that best fits your project, such as rectangle, oval, or the pen tool. Choose your desired mask shape carefully, as each option has its own advantages and limitations.
Draw the Initial Mask
Pick your desired mask shape rectangle, oval, or pen and draw or place it on the canvas over the area you want to keep visible. Don’t worry about perfection at this stage, as each mask type has its own pros and cons and can be refined later.
Adjust and Refine the Mask
Use your finger to draw an initial mask shape on the canvas, then resize, rotate, and reposition it to cover the area you want to mask. For better precision especially when using the pen tool adjust the anchor points as needed.
Feather the Edges (Optional)
Feathering softens mask edges and helps create smooth blends. Adjust the mask’s feather setting carefully use subtle values to avoid unwanted blur, as higher values will make the edges softer and more blurred.
Animate and Fine-Tune
Add keyframes to animate your mask over time, allowing it to move, expand, or change shape dynamically. Keep tweaking until you achieve the perfect effect and that’s it, you’ve created and applied your first mask in Alight Motion! With practice, you’ll gain speed and confidence, even with complex shapes.
Pro tips: Use rectangles for quick geometric masks and text, start with rough placement then refine, add light feathering to oval masks for natural edges, enable snapping for precise alignment, animate mask expansion to reveal images gradually, and mask motion paths to reveal moving text or graphics.
Avoid common mistakes: Always select a layer before adding a mask, close the mask shape fully, watch for uneven edges near borders, avoid excessive feathering that causes unwanted transparency, and ensure masks aren’t distorted or stretched.
Animating Masks for Dynamic Effects
Animating masks unlocks the true creative potential of masking. By changing mask shapes over time, you can create:
For example, a mask can follow an object as it moves across the frame, revealing it smoothly and naturally.
Using Masks for Color Correction
Masks are extremely useful for selective color correction. Instead of adjusting the entire frame, you can isolate specific regions.
Examples include:
This technique creates a polished, cinematic look without affecting the rest of the image.
Masks for Special Effects
Masking also opens the door to creative special effects.
You can:
By combining masks with layers and blending modes, you can develop unique visual styles.
Masking for Text and Titles
Text animation relies heavily on masking. Masks allow text to:
This makes masking essential for intros, lower-thirds, and branded content.
Masking for Social Media Content
Masking is especially valuable for short-form content on platforms like Instagram, Facebook, and YouTube Shorts. It helps:
Because viewers scroll quickly, clean and focused visuals are crucial.
Common Mistakes When Using Masks
Rough or Jagged Edges
Refine mask shapes carefully and use feathering sparingly to smooth edges.
Poor Mask Alignment
Zoom in and align masks precisely to avoid unwanted visibility.
Overusing Feathering
Too much feathering can make visuals look blurry and unprofessional.
Too Many Keyframes
Excessive keyframes make animations hard to manage and less smooth.
Tips for Professional Masking Results
Professional masking is about precision and intention.
Optimizing Performance While Using Masks
Complex masks and heavy effects can slow down projects. To maintain performance:
Optimized projects export faster and play smoothly.
Troubleshooting Masking Issues
If a mask behaves unexpectedly:
Patience and practice are key to mastering masking.
Learning Curve of Masking in Alight Motion
Masking may feel challenging at first, especially on mobile devices. However, with consistent practice, it becomes intuitive. Starting with basic shapes and gradually exploring advanced techniques is the best approach.
