Multi-speaker split screen
Two people, both on screen, switching to whoever is talking.
On two-person footage a single tracked frame keeps cutting away from whoever just reacted. Split screen stacks both speakers so the reaction is never off camera, and emphasises whoever is currently talking.
This is the default worth using on interview podcasts, and the reason podcast clips look markedly better with it on.

What about three or more speakers?
The frame follows the active speaker; split screen is designed for two.
