If you experience flickering lights in your video from your webcam, you can adjust the anti-flicker setting in the Logi Tune software. The frequency of your lights should be synchronized with your webcam to avoid having visible flickering on your video. This means you have basically instructed the camera you are using to take a picture every time the ON cycle happens.

In order to achieve synchronization you can choose between two settings;

• NTSC 60HZ 
• PAL 50HZ

This will vary depending on your location and environment, but Logi Tune will let you select either of the  options. NTSC is typically best if you are located in North America and PAL is better if you are residing in the EU.
