Basic question about shutter speed vs frame rate in Premiere (shooting 60fps vs slowing to 24fps in post)

Hi everyone, I have what I'm sure is a simple question but I just haven't been able to find the answer elsewhere.

I have been reading that when filming, a good practice is to try to set the shutter speed value at twice the frame rate to get the most natural-looking footage. I know there are lots of situations where you should not follow this rule, but let's just assume I want to stick to this approach at the moment.

My question is: how does this work when you're filming in a higher FPS with the intention of slowing that footage down later in post?

For example, I currently do a lot of shooting in 60fps on both my drone and my GoPro because I really like being able to slow 60fps down to 24fps for a bit of slow motion. But when I do this, should I be trying to set my shutter speed to 1/120 because I'm shooting at 60fps, or should I be trying to set my shutter speed to 1/50-1/60 if I know I'm going to slow it down to 24fps in Premiere later?

Hey

I shoot tons of high frame rate footage. We go ahead and follow the basic X2 rule an the footage looks great. I think it because the shutter speed is in relation to the speed of the action, not tied to the frame rate of playback. So slower footage doesn't need the slower shutter. In fact, a shutter speed equal to the frame rate would look blurry I believe.

Hope this helps,

Steve
