… from the datasheets it is not possible to interfere the actual technology these drivers are using. Judging from the formfactor of the PCBs, it’s PWM-based. That is exactly the technology I wanted to stay away in my design. The LEDs are driven in this design by high-frequency pulses and dimming is achieved by varying the pulse width. So potentially, you have an interaction between the high-frequency lightpulses and the camera sensor which can lead to flicker effects if you use very short exposure times. I have seen professional video footage of stage acts which suffer from this.
Presumably, these LED guys know what they are doing and use a high enough PWM frequency so that this is not an issue for the usual exposure times. Most of the TV-shows have no issues with that. For my setup with exposure times of around 1/32 seconds, it is certainly not an issue, but going down to exposure times of 1/4000 or lower (if you want to freeze a non-stopping film strip) I am not so sure. Maybe someone else does have experience here?
