What should we choose in the menu of the GoPro camera at AntiFlicker 50Hz or 60Hz?
To answer this question we need to see what these frequencies refers to. There are several television standards in the world, but the best known are NTSC, PAL and SECAM. In this article we will see how to choose correctly depending on the region where we are.
NTSC standard has been developed to be compatible with most color or black and white TVs. Even if the TV broadcast system has switched to digital, the number of lines of resolution and the frame rate it uses are the same as set by the NTSC format. NTSC is mostly found in North America, certain countries in South America, the Philippines, Myanmar, Taiwan, South Korea, and Japan. This standard uses FPS (frames-per-second) rate - 29.97. NTSC uses the 60Hz frequency.
PAL or "Phase Alternating Line" is a standard developed in the late 1950s in Germany, which was to eliminate certain weaknesses of the NTSC standard, such as signal quality in adverse weather conditions. The PAL standard uses the image frequency of 50Hz and is used for transmission in the countries where it was adopted. This standard uses FPS (frames-per-second) rate - 25. The PAL standard is used in Europe, China, India, Australia, Africa but also in other regions.
SECAM is the third standard and is used in some countries in Africa, Russia and France.

What should we choose NTSC or PAL? If you're making videos for global viewing, it's best to use the NTSC standard because most of PAL DVD players and VCRs can play NTSC videos, but NTSC platforms generally don't work with PAL content.
Difference between NTSC and PAL
Many video cameras today have the ability to change frequencies between 50Hz (PAL) and 60Hz (NTSC). If your camera has this option, simply match your camera's frequency to the ambient frequency. Once set to the correct frequency, you can safely use any of the frame rates or shutter speeds offered by your camera.
