Why do videos shot under light sources have horizontal stripes with my YI LITE Action Camera?

a. Please check whether PAL or NTSC is being used when recording. If the TV format is PAL in your country, please use the PAL video format and use NTSC standard video vice versa.

b. Since the light flicker frequency and video shooting frequency are not the same, resulting in a horizontal stripe in videos taken under light sources. Please avoid video shooting under artificial light. Shooting under natural light is preferred.
