FLUX 3 Cinematic Inserts

Build one standalone shot around one motivated physical or atmospheric event: B-roll,

a bridge, a material detail, a capability test. Reroute when success requires supplied

media (flux-3-keyframes-continuation), exact typography, frame-accurate sync, a

multi-step mechanism, close human performance, or finished ad copy; those need

conditioning or post, not a text-only generation.

Before writing, settle the contract in one sentence: the visible cause, the physical

response, and the payoff. Then pick a proven lane from

references/field-guide.md (atmospheric light in a medium,

wet reflections, viscous macro, tactile contact and ignition, restrained noir); treat

anything it marks experimental or parked as a test, not a promise.

Write the shot in this order:

• Opening frame: composition, subject, setting, light.
• Visible cause: source and contact point in the same frame as the response.
• Physical response: direction, material behavior, restraint.
• Payoff: one final state that works as an edit point or a still.
• Continuity contract: same set and geometry; no cuts, transitions, frozen or

repeated frames, or resets.

• Audio intent: name material textures; route critical sync and mixing to post.

Camera is one physical contract: framing, angle, movement, focus. A locked-off camera

cannot track; an extreme close-up cannot establish. Locked and deliberate by default;

move only when it serves the event.

Style must be visible: "tense" becomes rigid posture, shallow breathing, and a slow

push-in; "vintage" becomes a named capture format, grain structure, and practical

light. No unmotivated sparks, bells, or effects.

Draft first (draft: true) while the concept is unproven, and judge the draft on event

legibility, composition, camera, and continuity; softness is the low-step trade and

resolves at full quality. Iterate as a ladder, one consequential change per variant:

event geometry, then material or light, then composition, then duration. After two

structurally similar misses, change the concept or the production method, not the

adjectives. Review the result with

references/review-scorecard.md: a technically valid

clip still has to be useful, physically legible, deliberate, and interesting.

Hand the finished prompt to flux-3-generate as a text-only request, with the risks and

anything post must own.
