Many LED luminaires do not use high frequency drivers to eliminate flicker in the same way high frequency fluorescent lamp ballasts eliminate flicker. Shooting video in environments with a lot of LED luminaires can produce video with distracting flicker. Viewers do not want to be distracted, and will switch off if they see annoying flickering.
LED Lighting Video Recording Tips?
To eliminate flicker, for 120V 60Hz locations, the best shutter speeds to use are at multiples of 120, while at 220/230V 50Hz power locations, best shutter speeds are in multiples of 100. This Telegraph video seems to have been shot at 25 fps, which may be why a lot of annoying flicker can be seen. For flicker free video in 50Hz electrical environments, shooting at 50 or 100 fps should give best flicker free results, for 60Hz, 60 to 120 fps should give best results
For 50Hz 1/100, 1/50, 1/33, 1/25. 50 & 100 fps should = best results
For 60Hz 1/120, 1/60, 1/40, 1/30. 60 & 120 fps should = best results
This video should most likely have been recorded at 100 fps or 50 fps. In post-production there is no fix for this strobing effect. The only solution is to test other camera settings & re-shoot.
A best approach when Designing Architectural Lighting is to specify LED luminaires with high frequency, flicker free dimming drivers.
