Marking the beats

A beat is one thing the viewer must see or hear. Every beat gets a one-line purpose, or it goes.

Read before you divide. The plan is your shot plan, written from the approved treatment. Read everything the treatment decided (its scene paragraphs, camera language, edit section, on-screen text and risk pass; see Writing the treatment), and write nothing that contradicts it. If the treatment's pace and the model's limits truly clash, raise it with whoever approved the treatment. Never simplify quietly.

Mark the beats of each scene. A beat is any of these: an action event, a reveal, a product interaction, a spoken line, an on-screen text moment, a reaction, or a listening beat where the scene needs one. Each beat holds at most one product interaction. The beats serve what the scene wants, and its last beat is the "ends when" moment the treatment wrote (see Writing the treatment → The scene paragraphs and voiceover).

Give every planned reaction its type and latency from the reaction clock: overlapping, half a beat late, instant, or held then late (see Performance → The reaction clock). The plan's job is to give it room. A double take needs about 3 s of its window, and a slow burn at least 4 s. Add a 1–2 s hold to each for the editor: the handle lets the in-point move in the edit.

Give each scene's key reaction a pair [proven] as human craft; the AI fix is [best available, not yet validated]. Plan the face and the shot it is cut against (what she sees or hears), joined by a hard cut to a clearly new angle. Do this for key reactions only, and price the pair in the estimate. How the pair is acted, and its comedy form inside one wide frame, are in Performance → The reaction pair.

Give every beat a purpose (decided), in one line: what the viewer learns or feels. A beat or shot with no purpose is dropped. A client once cut a shot of a model doing nothing; the purpose line catches it before you pay for it.

Why: David Mamet builds a scene from simple shots whose meaning comes from what they are cut against, and the Kuleshov effect shows a neutral face read differently by the shot beside it. Generated faces overact, so putting the meaning in the cut is the stronger tool.
