The opposite might be useful too. Often when shooting outside there is too much light, and a high shutter speed is automatically used. Resulting in footage that has not enough motion blur. Ideally you would want to have the shutter speed at twice the frame rate for smooth looking motion blur. But I think this might be a little harder to add in camera or post. For example when filming someone "talking with their hands". You would want to add blur to their hands, but not necessarily to their head which is probably mostly stationary.
