Final answer:
In film and theatre, a 'straight cut' is the correct term used to describe the splicing of one shot to another without noticeable continuity devices, which differs from a jump cut and facilitates a continuous narrative.
Step-by-step explanation:
The splicing of one shot to another with no obvious optical continuity device, distinct from a jump cut which aims for disorientation, can be described with one of the provided options. In this case, the term that best fits the description is a straight cut. A straight cut, also known simply as a 'cut', transitions from one shot to another in the most direct and simple way without relying on special effects or visual tricks to maintain the narrative flow. Unlike a match cut that brings together two visually similar shots, or a cutaway that interrupts the visual narrative to show something unrelated, a straight cut provides a clean and rapid changeover between scenes, contributing to a continuous narrative in a film or theatrical production.
