Challenge 1: Rapid Game-Camera Switching — Solution Walkthrough

The best fit:

Cut.

Why, per this chapter's own material:

Cut is genuinely instant, zero duration, with no visual effect at all
— exactly appropriate when speed and responsiveness matter more than
smoothness, which this chapter names directly as rapid-fire
game-camera switching as its own specific example. Any added delay
during a fast-paced moment would feel sluggish and out of sync with
the action.

Why Fade would be a worse choice here:

Per this chapter's own material, Fade cross-dissolves between
outgoing and incoming Scenes over an adjustable duration — even a
short Fade introduces some visible delay and blending between the two
camera angles, which during genuinely rapid switching would feel
sluggish and could blur together fast-moving action during the exact
moments viewers need clarity most.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise is a direct, practical application of this chapter's own
Cut-vs-Fade distinction to the exact scenario the chapter names as
Cut's own ideal use case.
