Yesterday, I took some shots from our Christmas Tree. I only used the light coming from the electric christmas tree lights. 220 Volts, 50 Hz.
Shot with the Blackmagic Pocket Cinema Camera, CinemaDNG RAW, 24 fps, 180 degrees Shutter angle, ISO 800. I used the Zenit Meteor 5-1 lens using f/1.9 aperture and various focal lengths 17-69mm.
I experienced a quite severe strobe effect in the form of pulsating waves. Anyone that has a clue of why? My first thoughts was that it came from the christmas tree lights and the frequency it created (50 Hz).
This guy seems to confirm my suspicions: https://www.youtube.com/watch?v=T3iWvdJzx84
The christmas tree shot is a part of a larger project which I shot on 24 fps. If the strobing comes from a faulty frames per second setting, what setting should I have used instead? And how to intercut it with the other footage shot on 24 fps in DaVinci Resolve?
Or is there another explanation for the strobe effect? Is there a way of working around it without changing the frame per seconds setting?
Apprecieate any advise. Thanx.
And a Merry Christmas!
