Part2. What is Masking?

Masking, in typical meaning, refers to adding an extra layer to an object to make it more expressive. Similarly, masking video editing is done to make your video more attractive by adding more beautiful layers, or to creatively camouflage a specific part or object in a video.

Just photoshopping is for images, masking is for videos. Because of masking, any video clip can contain any visual effect that you like. You can change the background, clone a face or a person, or pixelate if you want to blur something. And it’s not just about covering things, there is an entire set of tools that you can benefit from.

The process of masking videos involves covering specifics of video while shielding parts of the footage, and adding desired special effects in the targeted areas. Let’s look at how to mask a video in advanced editing:

Part3. How to Use DemoCreator to Mask a Video

To mask a video in DemoCreator:

In the toolbar, find the Mask effect. Drag the effect to the video clip in the timeline. Notice that the video is now shown in a circle shape.


Click on the Mask icon in the Properties area. This lets you adjust the width, height, size, location and feather of the mask, as well as invert the mask.

X / Y – Use the X and Y options in number values to adjust the Abscissa position of the mask.

Width / Height –

It is easy to adjust the width and height of the mask by setting the percentage for the mask.

Feather –

You can apply the feather effect by adjusting the percentage. The higher the percentage, the smoother the edges of the mask.
