Why do videos shot under light sources have horizontal stripes with my YI 4K+ 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 PAL video format and use NTSC standard video and vice versa.
b. Since the light flicker frequency and video shooting frequency are not the same, it results in horizontal stripe in videos taken under light sources. Please avoid video shooting under artificial light. Shooting under natural light is preferred.
