Why your vertical brief needs a retention beat table

Teams often ship vertical scripts with strong opening lines and weak middles. That is rarely a talent problem—it is a planning problem. A retention beat table maps each checkpoint to a concrete proof: product demo, customer quote, on-screen text, or silence.

We teach a four-column scaffold borrowed from the Sangju desk: second range, audience job-to-be-done, proof type, and risk note. When those columns stay empty, the shoot day invents filler. When they are filled honestly, the edit bay argues less.

The second paragraph is about discipline, not inspiration. Beats are promises to the audience, not decorations for producers. If a beat cannot be proven on schedule, cut it before call time, not in post.

Finally, treat the beat table as a living file. Update it when locations shift, not after the render finishes. The table is how you remember what you meant when the sun sets sideways on Gongseong-myeon lanes and everyone is tired.
