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.
