Hi folks,

 

Hope someone can clarify something for me :)

 

I'm filming a music video soon with a RED MX and I'll mostly be filming with 120fps in 4k/5k.

Whenever I set it to 120fps it automatically sets the shutter speed to 120.

 

Is there anyway to change it? And why does it lock the shutter speed at 120?

 

Allan

your shutter speed cannot be lower than the frame rate, and for normal motion you usually want it to be double, so shoot at 240 on the shutter for 120 frames per second if you want it to look normal.

Seeing as you seem to be extremely new to this, do also remember that as your shutter speed increases you're going to need a *LOT* more light!

Especially that old MX sensor which is very light hungry (double check it isn't the RED ONE M, which is even worse!).
