Have you ever captured a video that’s perfect in every way, except for one major flaw: it’s blinking or flickering uncontrollably? This can be frustrating, especially if you’re trying to showcase a product, demonstrate a technique, or simply share a memorable moment with friends and family. Fortunately, there are ways to edit blinking video and rescue your footage from the land of unusable content. In this article, we’ll explore the causes of flickering video, and more importantly, the techniques and tools you can use to fix it.
Understanding Flickering Video: Causes and Consequences
Before we dive into the editing process, it’s essential to understand why your video might be blinking in the first place. There are several common causes of flickering video, including:
Inconsistent Lighting
Fluorescent lights, LED lights, and other artificial light sources can cause flickering due to their inherent electrical pulses. This is especially true when filming indoors, where these lights are commonly used.
Camera Settings
Using the wrong camera settings, such as a shutter speed that’s too high or too low, can result in flickering. This is because the camera is capturing the lights’ electrical pulses, which then get translated into an annoying flicker on the screen.
Screen Recording
Recording a computer screen or mobile device can also cause flickering, especially if the screen is refreshing at a rate that conflicts with the camera’s frame rate.
Poor Video Quality
Low-resolution or low-framerate videos can exhibit flickering due to the limited amount of data being captured.
Digital Interference
Electrical interference from nearby devices or radio frequencies can also cause flickering in your video.
The consequences of flickering video can be severe, making it difficult or impossible to watch. Flickering can:
- Cause eye strain and fatigue
- Distract from the content or message being conveyed
- Reduce engagement and viewership
- Damage your professional reputation or brand image

What causes flickering in videos?
Flickering in videos can be caused by a variety of factors, including low-quality recording equipment, poor lighting, and incorrect camera settings. Additionally, flickering can also be caused by the type of recording format used, such as interlaced footage, which can exhibit a “flicker” or “rolling shutter” effect.
It’s also worth noting that flickering can be a result of issues during the video encoding process. This can occur when the video is being compressed and converted into a digital format, causing the flickering effect to become more pronounced. Understanding the root cause of the flickering is crucial in order to effectively fix the issue and produce a smooth, high-quality video.
Is it possible to fix flickering in videos?
Yes, it is possible to fix flickering in videos. There are various software and techniques available that can help reduce or eliminate flickering in videos. Some video editing software, such as Adobe Premiere Pro and DaVinci Resolve, have built-in tools and filters that can help fix flickering issues. Additionally, there are also third-party plugins and software available that specialize in fixing flickering issues in videos.
The approach to fixing flickering in videos depends on the severity of the issue and the type of footage. In some cases, simple adjustments to the brightness and contrast of the video may be enough to reduce the flickering effect. However, in more severe cases, more advanced techniques such as frame interpolation and deinterlacing may be required to fix the issue.
What is interlaced footage and how does it cause flickering?
Interlaced footage refers to a type of video recording format where each frame is divided into two fields: one containing the odd-numbered lines and the other containing the even-numbered lines. This format was commonly used in older TVs and video cameras. However, interlaced footage can exhibit a “flicker” or “rolling shutter” effect, especially when there is fast motion or panning in the video.
The flickering effect in interlaced footage occurs because the two fields are captured at slightly different times, causing a mismatch between the odd and even fields. This mismatch can result in a flickering or shimmering effect, especially in areas of high motion or detail. To fix flickering in interlaced footage, it’s often necessary to convert the footage to a progressive format, which captures the entire frame in a single pass.
How do I fix flickering in videos using video editing software?
Fixing flickering in videos using video editing software typically involves applying filters or effects that can help reduce or eliminate the flickering effect. In Adobe Premiere Pro, for example, you can use the “Flicker Reduction” filter to adjust the brightness and contrast of the video and reduce the flickering effect. In DaVinci Resolve, you can use the “Temporal Noise Reduction” filter to smooth out the video and reduce flickering.
When using video editing software to fix flickering, it’s important to carefully adjust the settings and parameters of the filters and effects to achieve the desired result. Over-correction can lead to an unnatural or “soft” look, so it’s essential to strike a balance between reducing flickering and maintaining the original quality of the video.
Can I fix flickering in videos without using video editing software?
Yes, it is possible to fix flickering in videos without using video editing software. One approach is to use online video conversion tools that can convert interlaced footage to a progressive format. These tools can help reduce or eliminate flickering in videos. Additionally, some video players and media converters also have built-in deinterlacing filters that can help fix flickering issues.
However, it’s worth noting that online tools and video players may not offer the same level of control and customization as video editing software. Additionally, they may not be able to fix more severe cases of flickering. In such cases, using video editing software may be the best option.
How do I prevent flickering in videos during recording?
To prevent flickering in videos during recording, it’s essential to use high-quality recording equipment and adjust the camera settings accordingly. For example, using a camera with a high shutter speed can help reduce flickering caused by artificial lighting. Additionally, adjusting the lighting in the recording environment can also help reduce flickering.
It’s also important to use a progressive recording format instead of an interlaced format. Most modern cameras and smartphones record in progressive formats, which can help reduce flickering. Additionally, using a camera with good low-light sensitivity can also help reduce flickering caused by poor lighting.
Are there any specific camera settings that can help reduce flickering?
Yes, there are specific camera settings that can help reduce flickering. One of the most effective ways to reduce flickering is to use a high shutter speed, typically above 1/120th of a second. This can help freeze the motion and reduce the flickering effect. Additionally, using a camera with a high frame rate, such as 60fps or higher, can also help reduce flickering.
Another approach is to use a camera with a “flicker reduction” or “anti-flicker” mode. This mode uses advanced algorithms to detect and adjust the shutter speed and exposure to reduce flickering caused by artificial lighting. Some cameras also have a “sync” mode that allows you to synchronize the shutter speed with the lighting frequency, which can also help reduce flickering.
