There are eight different reasons you might end up with flicking in your videos, some of which are easily preventable while others are a little harder to avoid. Below you will find all eight reasons and how you can reduce the chances of getting flicking in your footage. Prevention is far better than treatment! Remember 99.9% of the time you will see the flickering on your camera screen while recording so you can adjust settings on the fly.

1. Frame Rate Mismatch

   • If the frame rate of your recording device does not match the frame rate of the displayed content or the video editing project, it can lead to flickering. Inconsistencies in frame rates can cause frames to be displayed unevenly.

2. Lighting Conditions (usually fluorescent lights)

   • Changes in ambient lighting, such as fluctuations in artificial lighting or the presence of natural light, can cause flickering. This is more common in indoor environments with fluorescent lighting, which operates on a specific frequency.

3. Shutter Speed

   • If the shutter speed of your camera or recording device is not synchronized correctly with the frame rate, it can result in flickering. Misalignment between the shutter speed and frame rate may cause exposure variations between frames.

4. Screen Refresh Rate

   • Flickering can occur when the refresh rate of the screen being recorded does not match the frame rate of the recording device. This is especially relevant when capturing screens, as computer monitors typically have refresh rates that need to be synchronized with the recording settings. If your monitor has refresh rate options just adjust them down. Usually, 60FPS on a monitor is enough to remove flickering.

5. Interference from Other Devices

   • Electronic interference from other devices in the vicinity can contribute to flickering issues. This interference might affect the stability of the recorded signal and result in flickering artifacts.

6. Automatic Brightness Adjustments

   • Some screens and cameras have automatic brightness adjustments, and variations in brightness can cause flickering. This is common when recording screens that automatically adjust brightness based on content or ambient light.

7. Compression Artifacts

   • During video compression or encoding, artifacts may be introduced that manifest as flickering. This is more likely to happen when using lossy compression methods.

8. Inadequate Screen Capture Software Settings

   • Incorrect settings in the screen capture software, such as improper encoding settings or compression methods, can lead to flickering in the recorded video.
