Shutter angle

[JamesDucker]

Hey Guys,

Can anyone helo me with this question?

As I'm sure you know in Europe it is 50HZ and 60HZ in other countries (like America). Every set I've been on the frame rate has matched the shutter angle e.g. 24fps = 172.8 degrees and 25fps = 180 degrees. Until I saw recently on a shoot in America (where its 60HZ ) the movie been shot at 24fps and 180 degree shutter angle. Why would this be?

Hi @JamesDucker,

I don't really understand your question - you can set the shutter angle to 180° no matter what.

If I record at 24fps I can expose for 1/48th of a second if the camera offers it, if not, I choose the closest option the digital shutter offers (in this case 1/50th of a second).

The 50 and 60Hz comes from the AC-frequency of the power grid in the countries to make it possible to frilm "flicker-free" video if you use artificial lighting or have artificial lightsources in frame.
