emily2040 seedance-prompt
Before producing prompt text, a prompt-ready block, a rewrite, an example, or a compiled clip, load the Director's Read, classify the brief, and complete its canonical narrative or non-narrative record. Translate that record into visible or audible carriers and keep its internal labels out of final generation prose.
Build production-ready Seedance prompts from clear concepts or supplied reference assets. Treat the prompt as a short shooting brief: it must say what changes on screen, what the camera does, what the light and sound contribute, and what must stay stable. Keep final prompts under the platform prompt budget and remove filler before delivery.
Load the Director's Read before any drafting or compression, quick-ref for the checklist, reference-workflow for multimodal references, i2v-guide for image-to-video, first-last-frame-guide for first/last-frame work, examples-by-mode when examples are useful, shot-list-continuity for multi-shot professional plans, multishot-grammar for shot-label grammar, the shots-times-seconds budget, and cut placement inside one generation, and multilingual-community-examples for Chinese/Russian/Japanese/Korean/Spanish or mixed-language prompts. When sequence state is present, load prompt-compiler and compile only the current clip contract.
Intent
This is the translator between a scene that exists in someone's head and one that exists on screen. The user has already imagined it; the job is to lose as little as possible in transit. Success is a first generation close enough that they can react instead of explain. Each revision inherits everything the story has already decided and changes only what the reaction asked for - a draft is a conversation, not a restart.
Director Formula
Before filling slots, run the Director's Read gate. A brief with a dramatic story turn must have all ten canonical narrative fields completed. Observation/performance without that turn and utility briefs use the two-line non-narrative intent and refusal, with no fabricated psychology. Preserve expressive movement, rhythm, or delight when requested. For narrative work, name a single intention from the read and let it choose camera, lighting, blocking, performance, and sound together. Load directing-engine when the setup needs its deeper instrument and voice logic. The formula below is the container for a coherent setup, not a checklist of independent decorations; if a project voice is already set, keep this shot inside it.
The Director's Read is internal planning, not prompt copy. For narrative work, compile its turn, visible suppressed behavior, and non-transferable detail into visible or audible carriers. For observation/performance or utility in the non-narrative lane, carry the requested action, rhythm, information, or sensory change without inventing those dramatic fields. Do not paste labels such as POV, power shift, hidden want, or subtext into the generation prompt, and do not ship an abstract feeling where blocking, gesture, prop use, camera endpoint, motivated light, dialogue contradiction, silence, or a sound cue can carry it.
Use Subject + Action + Scene + Camera + Lighting/Style + Audio + Constraints. Put the subject and primary action first because early clauses set the shot hierarchy. Do not force every slot if a reference asset already shows the information; for I2V, describe only the motion, camera, timing, transformation, audio, and preservation constraints that the still image cannot show.
| Slot | Use for | Prompt-ready pattern |
|---|---|---|
| Subject | The anchor the model must track. | Original ceramic perfume bottle on black acrylic, label preserved exactly |
| Action | The visible change. | condensation beads form and slide down the glass over five seconds |
| Scene | Only what is not already in references. | quiet rain-lit kitchen counter, shallow depth of field |
| Camera | One primary move with endpoint. | slow dolly-in from medium product shot to macro label detail |
| Light and style | Physical light plus safe visual language. | warm practical key from frame left, cool blue rim, clean commercial realism |
| Audio | Ambient bed, SFX, dialogue, or silence. | Sound: low room tone, soft glass chime on final frame |
| Constraints | Preservation and exclusions. | do not alter logo, shape, label, or cap geometry |
Mode Gate
Choose the mode before drafting. T2V needs subject, action, scene, camera, light, style, and constraints because nothing is visible yet. I2V starts from @Image1 and adds only motion, time, camera, lighting transition, audio, and preservation. V2V should map @Video1 to source clip, camera move, action rhythm, blocking, edit target, or extension anchor rather than accidentally transferring identity. R2V must list every reference role and state what must not transfer. FLF2V uses @Image1 as first frame and @Image2 as last frame, then describes only the continuous transition.
| Mode | Drafting priority | Common mistake | Repair |
|---|---|---|---|
| T2V | Build the whole shot in compact layers. | Too many events in one clip. | Keep one visible beat and one endpoint. |
| I2V | Preserve visible identity; add motion. | Re-describing the image until the product or face drifts. | Say preserve @Image1 exactly; add only dynamic changes. |
| V2V | Transfer motion, camera, or timing. | Copying unauthorized likeness or scene details. | Use owned/licensed/authorized references and restrict transfer role. |
| R2V | Assign separate roles to each asset. | One reference asked to control identity, pose, scene, and style. | Split roles or prioritize the most important role. |
| FLF2V | Move from first frame to last frame. | Treating the last frame as vague mood instead of endpoint. | State @Image2 is the final visual target. |
| Edit | Preserve the source clip while changing one layer. | Rewriting the whole scene and losing continuity. | Say @Video1 is the source clip; change only... |
| Extend | Continue from accepted source footage only. | Starting from a planned ending or inventing the clip state. | Route to seedance-continuation and use the observed end state. |
Sequence Boundary
The generic prompt skill must not independently invent continuation state. If the user asks to continue, extend, make part two, or use a previous clip, route to seedance-continuation unless the accepted clip/final frame and observed end state are already present in the sequence state.
For sequence prompts, preserve project_id, clip_id, parent_clip_id, continuity locks, exact reference tags, the actual opening state, completed beat exclusions, and reserved future beats. The final prompt remains natural language and covers only the current clip.
Prompt Build Process
First, load the Director's Read, classify the brief, and complete the correct lane record before prompt compilation. For a narrative lane, identify the single visible beat and the intention it serves, then map the read to carriers; for a non-narrative lane, keep the concrete utility intent and refuse invented drama. Next, assign reference roles before adding adjectives. Then write a compact first draft in the director formula order. Finally, run a self-check and, when loaded, the directing coherence test from directing-engine: one main subject, one main action, one motivated main camera move, physically motivated lighting, performance written as a visible gesture rather than an emotion word, assigned character tags, sound intent, and no hollow boosters.
Compression Rules
When the prompt is too long, cut in this order: duplicate style adjectives, generic quality words, background details visible in references, secondary camera moves, secondary actions, and speculative emotional labels. Keep preservation constraints, action timing, and role maps. If a user requests a bilingual or mixed-language prompt, use language mixing only for clarity: reference roles, dialogue language, technical camera terms, and safe production constraints. Do not use another language to hide unsafe intent.
Output Contract
Return:
- Mode: T2V, I2V, V2V, R2V, FLF2V, edit, or extend.
- Reference role map, if any.
- Final prompt under the verified active-surface prompt budget.
- Optional Chinese compressed version when useful.
- Shot-list or delivery note when the prompt belongs to a professional sequence.
- Safety or copyright note when relevant.
Before finalizing, run an anti-slop pass and remove vague quality boosters.
