What characterizes a crab shot in film production?

A crab shot in film production is characterized by its viewpoint taken from a confined space, where the camera is often positioned in a way that resembles a crab scuttling sideways. This type of shot is typically used to create a sense of intimacy or proximity to the action, allowing the audience to engage more closely with the subject. The confined space, such as narrow hallways or cramped settings, can enhance the dramatic tension or highlight character dynamics.

The other options do not accurately define a crab shot; they refer to different types of shots that do not embody the specific visual quality and positioning associated with a crab shot. For instance, shots from an aerial perspective or wide outdoor scenes convey a different concept of framing and space, as do shots from a moving camera, which could imply a variety of other cinematic techniques.
