  1. Hi. I am three weeks into a 4 week show and today our dailies colorist alerted us that we suddenly are experiencing a "pulsing" in the blue channel in footage we shot early this morning. Something akin to an out of sync HMI when shooting film. But we are not shooting film. We are shooting with two Sony F55s. The issue is with both cameras so we suspect the lights. Our lights are Arri Sky Panels, M8's, M18's and M40's. The "pulsing" can not be seen by the human eye during playback but can be seen in the RGB Parade. The footage is usable but there is a concern about potential red flags for QC. Our schedule is extremely tight. We have zero time to do any sort of testing of our lights. Does anyone have any insight and or experience with perhaps the Sky Panels resulting in blue channel problems? thanks f
