Nicholas A Micros Posted December 28, 2008 Share Posted December 28, 2008 (edited) I am talking to a friend who has some house hold electrical work and we are wondering if you could use a average ballast in film or video. Doesn't matter what kind of light it is or wattage. Just a hypothetical question. Seems a lot cheaper.

Premium Member David Mullen ASC Posted December 28, 2008 Premium Member Share Posted December 28, 2008 We shoot in locations all the time that have ordinary ballasts in fluorescent fixtures. Generally you just have to be in the "safe" window for the hertz flicker. For 60 Hz fixtures, 24 fps crystal-sync at a standard 180 degree shutter angle is within that safe window.

Is there a formula to calculate the safe window? Link to comment Share on other sites More sharing options...
