Slow motion by default is set for NTSC not PAL standard so its set to  120fps which PAL users cant shoot in room interior lighting as they will  need to shoot on 100fps 4x or 200fps 8x (room lighting 50Hz) thus interior lighting causes constant flicker if  you are based in PAL countries. while shooting in camera slow motion.

Dji Team please add PAL & NTSC options for users to choose in the menu settings in next update (hopefully soon)
