What Is Video Flickering?
Video Flickering can be described as a light source emitting an unsteady glow, visible only to the camera (and not the naked eye). It can irritate and even lead to a feeling of exhaustion after long-term exposure. It's essential to determine what is causing the flicker in your footage.
Possible reasons include shooting a time-lapse where the exposure is set to auto, filming on computer or projector screens, or when the shutter speed or the frame rate doesn't jive with the lighting being functional. The video flicker removal tools can reduce or remove the flickering in your video.
In essence, the brightness of a video or screen will fluctuate continuously and add a black screen to the video online. When these changes are frequent enough to be detected by viewers, it is referred to as flickering.

As a result, even when camera settings remain the same, the lighting results can vary greatly.
There are several methods for removing flicker from video, including adjusting camera settings during filming and using specialized video editing tools in post-production.
