Alternating events in two places builds tension and comparison.
When two characters do different things at the same moment, like "a brand getting ready vs. a customer waiting".
Build each strand of shots with its own fixed background plate and lighting block, and tell them apart by place and color. Alternate them at 1 to 2 seconds each, and shorten the cuts toward the end to drive the two strands toward the scene where they meet.
Four-shot alternating sequence, 1.5 seconds each, getting tighter: Shot 1, a baker slides a cake into a glowing oven; Shot 2, a delivery cyclist races through rainy blue-lit streets; Shot 3, close-up of the baker checking a clock; Shot 4, close-up of the cyclist skidding to a stop at the bakery door. Fast hard cuts with a ticking clock sound.
