problems with a large projector screen flickering
« on: January 29, 2016, 04:27:30 AM »
Hi folks,

Recently I shooted some training seminar for some companies.
they had a large projectors screen and ambient lights.

I shoot on PAL system 50Hz. camera setting(PAL, 1/50 shutter speed) but the projector screen just keep flickering :(

anyway to avoid the projector to being flicker?
I know highend pro cam has features that fix this, but does ML can do some tricks here?

I did played with the camera setting trying to fix that.
here is what I did:
-I tried using difference shutter speed, nothing helps here.
-then I changed to the NTSC in camera, fixed the flickering. BUT I did not shoot on NTSC at the end, because I am not sure that I will get the ambient lights (50hz) banding at the end. I cannot risk for this. it will completely ruined all my shoot :(

so anyone can give me some opinion what should I do, beside getting a pro cams? ::)

Thank you!

Just found the fps overrite features does the job :)
here is the sample I am able to remove the flickering from the TV~
