The script wins

Good films are decided before they are built. Mixture’s agents plan in the open — a brief, a pitch round, a script, a storyboard, an animatic — and the plan follows one rule when its parts disagree: the script wins.

The ladder

Every rule about pictures defers to the words and to what the words make the viewer feel. When two instincts about a beat conflict, the higher one wins, and the agent sacrifices from the bottom:

1. Feeling — what the viewer feels after the beat. It is what they remember; lose it and nothing else you kept matters.
2. Story — the beat causes the next one. Between any two beats you can write but or therefore; if only and then fits, the beat goes.
3. Rhythm — events land on beats and phrases, holds have rest.
4. Eye — the next event starts where the eye already is, or something carries the eye there.
5. Frame — composition, depth, one focal point, the type ramp.
6. Space — 3D and camera consistency, literal continuity.

This is Walter Murch’s ordering for a film cut, adapted for motion pieces. Agents tend to protect the bottom two because they can be checked; Mixture asks them to invert that, and gives them the checks for the top four instead.

Beats that cause each other

The beat sheet an agent writes has a Link column, and only two words are allowed in it: but — a turn, the gap between what is and what could be — or therefore — a consequence. A beat whose only honest link is and then is merged or cut before the storyboard. Every film gets at least one but; that is the contrast that makes the ending feel earned.

The script has rules of its own: it never narrates the picture (the frame carries the noun, the voice carries the stakes); it lets the viewer finish the thought; it feels shorter than the film, with written pauses where the picture owns the moment.

A picture that hands the eye across

The sheet also has an Eye column: where the viewer is looking when a beat ends, and where the next beat’s first event starts. In Mixture both are known positions. Then the agent decides, in bands that come from film editing: within about 15% of the frame the eye stays put and the world changes around it; the opposite third on a beat is a jolt the viewer feels as a section change; 20–30% away is a drift, the unsatisfying middle, and the fix is a carrier — the one thing that crosses the cut, at matched position and speed.

Every seam gets a verb, and each verb is something Mixture can do: carries (the same layer persists), becomes (a morph), hands off (an exit that points at the next entrance), occludes (a foreground plane covers the swap), reveals under (a mask or scroll), punches into (a camera step on the beat), cuts on (a hard cut that keeps direction, colour or silhouette).

Measured, not vibed

When an agent checks its work, Mixture’s audit reports numbers the eye is bad at: how much of the film stands still, where the dead runs are, and an eye line — where the motion is from frame to frame and how far it hops, banded as match, drift or jolt. A drift is a seam to re-plan; a jolt on a planned section change is fine. Agents read the same doctrine in their plan-mode skill, with a worked beat sheet.
