Moiré Pattern

What is a Moiré Pattern?

A Moiré Pattern is a visual perception that occurs when viewing a set of lines, dots or patterns superimposed onto another similar set of lines, dots or patterns, where the sets differ in relative size, angle or spacing. This can lead to a variety of unusual and interesting visual effects such as waves, spirals or even three-dimensional appearances.

Understanding Moiré Pattern in Videos

Moiré Patterns can be both a fascinating visual effect and a nuisance when it comes to video production. They can appear when shooting finely textured objects or patterns, like fabrics, distant buildings or other similar subjects. The interference between the object’s pattern and the camera sensor’s pixel grid creates this effect.

How to Prevent Moiré Patterns

While sometimes used for creative effects, Moiré Patterns are often unwanted in professional video production. Here are a few ways to prevent them:

Adjust the Camera Angle or Distance

– Changing the angle or distance between the camera and the subject can eliminate the Moiré Pattern. Experiment with different angles and distances until the pattern disappears.

Use a Camera with an Anti-Aliasing Filter

– Some cameras come equipped with a built-in anti-aliasing filter that can help reduce Moiré Patterns.

Change the Aperture

– By changing the aperture, you change the depth of field and the amount of detail that the camera captures, which can help eliminate the Moiré Pattern.

Post-Production Editing

– If you can’t prevent the Moiré Pattern while shooting, you might be able to remove it in post-production. Software like Adobe Premiere Pro and Final Cut Pro have tools that can help with this.


While Moiré Patterns can sometimes add an interesting visual effect, they’re usually unwanted in professional video production. Understanding what they are and how they’re created can help you prevent them or remove them in post-production. As always, the best way to deal with Moiré Patterns is to experiment with different techniques and see what works best for your specific situation.
