A webcam that freezes periodically is usually caused by insufficient CPU resources, USB bandwidth issues, or unstable drivers. Check your CPU usage (Task Manager on Windows, Activity Monitor on Mac) — if CPU is above 80%, close unnecessary apps to free resources. If you're using a USB hub, connect the webcam directly to a port on the computer. USB 2.0 ports can bottleneck HD cameras; use a USB 3.0 port if available. Update your webcam drivers: on Windows open Device Manager > Cameras > right-click > Update driver. Lower the camera resolution in your app: Zoom Settings > Video > uncheck HD; this reduces CPU and bandwidth load. If the freeze correlates with network drops, the issue is bandwidth, not the camera — run a network test. On Mac, reset the camera driver with Terminal: sudo killall VDCAssistant. Disable virtual camera overlays (Snap Camera, backgrounds) that add CPU load.
