Temporal light artefacts

Temporal light artifacts are things we see when watching something, like a movie or TV show, that are not supposed to be there but appear as a result of the way things are displayed on the screen.

Think of it like a flip book. When you flip through the pages quickly, it looks like the images are moving, but in reality, they are just a bunch of still images.

The same thing happens with movies and TV shows. They are made up of a bunch of still images that are shown to us really quickly, and our brains put them together to create the illusion of movement.

Sometimes, when these still images are shown too quickly or not in the right order, we may see weird things happening on the screen, like flickering or ghosting. These are temporal light artifacts.

Many factors can contribute to these artifacts, including the refresh rate of the screen, the frame rate of the video, and even the way our eyes move when we are watching something.

Fortunately, most of the time, temporal light artifacts are not too distracting or noticeable. But in some cases, they can be very annoying and make it hard to watch what you are trying to enjoy.
