Oh, and just for future reference, the 180 degree rule has nothing to do with shutter speed. It's the imaginary line between two people cinematographers use while framing shots. For example, you wouldn't begin a scene that has two people talking with the camera positioned on their left side, and the suddenly switch from one persons POV to their right side as it would look as if they suddenly were talking to the back of the other person's head. The general rule for shutter speed if double whatever your frame rate is.I think that, in the context of this thread, the 180 degree has everything to do with shutter speed and is well-known to mean specifically double-the-frame-rate, as is already stated in this thread.
And yes, the 180 degree rule that you cite is a common rule of composition.
For future reference, you might want to clarifying the following.
Be careful with bumping up the shutter speed too much on DSLRs though, as at higher levels it can create clipping and rolling shutter, which you definitely do not want.It is my understanding that rolling shutter is not caused by shutter speed at all, as you seem to imply. Rolling shutter refers to how the data are read off the sensor and occurs on regardless of shutter speed or frame rate. It is most noticeable on fast motion, regardless of shutter speed. I'm also unsure of your use of the term "clipping". I have always used "clipping" to refer to loss of detail in bright objects because the sensor "clips" by reaching its RGB highest value. This is usually caused by an image being overexposed. It seems that a high shutter speed would (holding light, ISO, and aperture constant) go against clipping. But, perhaps I am unaware of another common meaning of the word "clipping" when referring to video.
