Webcam Flickering in Zoom – Stop It

Webcam flickering is usually a "Power Line Frequency" mismatch (50Hz vs 60Hz) between your room lights and the camera sensor. Againly can inspect the relevant local evidence and propose a fix plan for review.

Why this happens

• Frequency Mismatch: If you are in Europe (50Hz) but your camera is set to 60Hz (standard in USA), you will see horizontal bands.
• Auto-Exposure Loop: Zoom's low-light correction is fighting with your room's LED or fluorescent lighting.
• USB Bandwidth Throttling: If too many devices are on one USB hub, the camera frame rate can drop, causing a perceived flicker.

Fix it manually

1. Change Frequency: In your camera's "Advanced Properties" (found in the Camera app or Zoom settings), change the Power Line Frequency to 50Hz or 60Hz.
2. Disable Low Light Adjustment: In Zoom Settings > Video, uncheck "Adjust for low light" to stop the sensor from hunting.
3. Manual Exposure: Lock your exposure setting to a fixed value instead of using "Auto."
