FLICKERING practical bulbs


Recommended Posts

Why is dslr cameras if we shoot a scene with a practical tungsten or LED bulb it causes flickering in the video footage?? I know a bit that the frequency of light doesn't match the frequency of camera but if I take my shutter speed from 1/120 to 1/30 there if no flickering seen in the video footage. Why?   What will happen if I use cine cameras ( it has shutter angle ) ?

Roughly speaking you want to make your shutter angle a multiple of the countries frequency... eg.. 1/50th /1/100th in 50Hz / 1/60th/120th.. in 60Hz countries .. for "normal" motion blur in cine mode there is a 180 degree "rule".. shutter is twice frame rate.. but if your shooting say 23.98p in a 50Hz location use 1/50th.. even if you have a 1/48th option.. to avoid flicker from practical lights ..  LED is also tricky as if they are in anyway dimmed then will flicker what ever you do.. !
