Last Updated: 25th November, 2021
This effect is called moiré andiscaused when a fine pattern in the subject (such as theweavein a fabric or very close, parallel lines in architecture)matchesthe pattern of the imaging chip. In order to reduce (oreliminate)moiré, a special anti-aliasing filter ismounted inthe camera.

Just so, what is moire in video?
Moiré pattern occurs when a scene oranobject that is being photographed contains repetitive details(suchas lines, dots, etc) that exceed the sensor resolution. Asaresult, the camera produces a strange-looking wavy pattern asseenbelow: Image courtesy of photo.net.
Similarly, how does the moire effect work? Moiré effect is a visual perceptionthatoccurs when viewing a set of lines or dots that is superimposedonanother set of lines or dots, where the sets differ inrelativesize, angle, or spacing. The moiré effect canbe seenwhen looking through ordinary window screens at anotherscreen orbackground.
Likewise, people ask, what causes moire?
Moiré occurs when a scene or anobjectbeing photographed presents repetitive details. Theseinclude, butare not limited to, lines and dots. This effect iscreated by thepattern if it exceeds the sensor's resolution. Whenthis happens,the camera creates a strange lookingimage.
What is color moire?
Color moiré is an artificialcolorbanding that can appear in images with repetitivepatterns of highspatial frequencies, like fabrics or picket fences– or yourcomputer screen. It is affected by lens sharpness,the sensor'santi-aliasing (lowpass) filter (which softens theimage), anddemosaicing software.
