Spare attention is the enemy
Reading a chat does not use all of someone's attention. Whatever is left over goes looking for something else, usually the next video. Motion underneath occupies it.
It must not need following
The footage works precisely because nothing in it matters. A clip with its own story competes with yours and both lose.
Choosing
Bright, fast footage suits comedy. Calmer footage suits tension. If in doubt, parkour is the safer default.
