Flickering can be a significant issue for video production, mainly when shooting under artificial lighting or with varying frame rates. It can detract from the quality and atmosphere of the footage, making it difficult to watch or edit. Fortunately, there are ways to reduce or prevent flicker both in the camera and post-production.
While it may not be visible when you look at the light source directly while capturing video or taking pictures, you can spot irregularities in the resultant image or video due to the flickering. Further in this article, we will discuss video flickering issues and methods to remove flicker from video online.

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. It is due to fluctuations in fluorescent lighting, such that when a photo is taken at one moment, the light might be on, while at another moment, it is off. As a result, even when camera settings remain the same, the lighting results can vary greatly.

Video flickering occurs when the camera captures the rapid changes in brightness during shooting. It happens when the frame rate and shutter speed combination do not charge the same amount of light, causing the light to appear different. The outcome of this is visible flickering in the video.

How To Avoid Video Flicker When Recording Videos?
Flickering is expected due to specific frame rates and shutter speed patterns when using artificial lighting. It is preferable to take steps to prevent it from happening instead of fixing it in post-production. There are some techniques you can use to prevent flicker from occurring.
Prefer Shooting In Natural Lighting
Using natural lighting is ideal for avoiding flickering problems when shooting video. Lighting is an essential element of successful video production, and the best way to ensure your footage is stable and consistent is to utilize the available natural light. It is the best way to guarantee your videos are free from any undesirable flickering.
Keeping your camera settings in check is essential to avoid issues with your videos. Make sure to adjust the shutter speed and frame rate in particular and support the values nearby possible without making them the same. For example, setting the frame rate to 120 fps and the shutter speed up to 125 can prevent flicker from appearing in your videos.
The Flicker-free tool calculating application can be a great asset when capturing footage under artificial lights, as it allows for the calculation of frame rate and suitable shutter speed combinations that will help to minimize flicker.
Cameras with modern CMOS sensors are now available to counter flickering effects caused by luminous LED lights, traffic signals, and other artificial lighting sources. A range of these cameras can prevent video flickering when recording footage to create a different cinematic and lifelike outcome with video flicker removal online.
NTSC OR PIL
Using the right lighting frequency is critical when capturing any image. If shooting in multiple locations, consider setting your camera to NTSC. It will help the device adjust to different lighting conditions in each region. If you are working in the same area, switch over to PIL to ensure the camera is recognizing the intensity of the lighting.
Flickering in videos is an annoying problem that makes a video look imperfect. To fix it, the cause of the flickering needs to be figured out, which could include adjusting the camera settings and lighting conditions during filming. Once the footage is shot, certain methods are helpful to remove flickering from video online by applying filters and presets from the editing software. It also include several picture-editing tools, like the ability to resolve any flicker that is visible on camera during filming.
Is it possible to remove the flicker from the video?The best way of video flicker removal online is to shoot in either natural or continuously focused artificial lighting, as using a shutter speed very close to a known safe speed can decrease flickering frequency but won't eliminate it.
What is the frame rate of a flicker?The human flicker fusion threshold, which measures the number of frames presented per second for showing a sequence of moving images, is usually between 60 and 90 Hz. Occasionally, this level can increase to a level that is one order of magnitude higher.
What is the flicker setting on the camera?If you take a picture with a high shutter speed under a light source such as fluorescent light, the flickering of the light will cause the final image to be unevenly exposed or have inconsistent colours across the frames if done with continuous shooting.
What causes film flicker?When filming, a few elements exist to consider, such as the light source, camera settings, and combining the two. If the shutter speed and frame rate of the camera synchronize incorrectly with the rhythm of the light, then the video footage will flicker.
