I was perhaps getting my reasoning slewed.

It was my understanding that videos were shot in either 24 fps or 30 fps for normal viewing speed.

To achieve the ‘perceived realistic’ motion, the shutter speed should be the inverse of 2x frame rate.
ie. shutter speeds of 1/48sec or 1/60sec respectively. 

I am unclear why a video camera needs 1/10000 sec as it would need a 5000fps frame rate, unless high speed motion?

At the more normal slow shutter speeds in bright light without small aperture control the film could blow out.

However, if small apertures don’t give the desired dof…then the only alternative is to reduce the incoming light with a ND filter to pair with the shutter speed.
