default 180 degree shutter speed

When I change the frame rate I always have to edit the exposure time. Is there any possibility to set the shutter to 180 degrees as a default for all frame rates?

Yes that is correct- more frames per second require more light striking the sensor- beyond 120FPS you need a lot of light to get the same look.

" Is there any possibility to set the shutter to 180 degrees as a default for all frame rates"

that would be great if it were not for the physics involved. At 120fps and beyond you don't use a shutter at all- mainly because it cannot refresh fast enough.

(this is the same on film cameras - after a certain point the shutter is effectively off)

Sorry. Found the entry in "modes".

I think you are refereing to absolute shutter vs relative shutter mode on the red. One stays fixed and the other automatically adjusts when you adjust the framerate.
