higgsfield-seedance
Higgsfield Seedance Director rewrites scene descriptions into Seedance 2.0-compatible prompts using a six-slot cinematography formula (camera, subject, action, setting, style, lighting) and diagnoses content filter rejections through preflight linting. Use when the user needs Seedance prompts, reports generation failures, faces flagged content, or encounters delayed rendering issues to prevent credit waste on rejected submissions.

# Higgsfield Seedance Director
## QUICK FACTS
*Generated-checked block (scripts/build_index.py verifies anchors). Read the linked sections for full context — these lines are routing aids, not the rules themselves.*
- The filter is an LLM reading full-scene intent, not a keyword blacklist — describe a SCENE, not a subject; fix the voice first [→](#the-filter-model-read-this-first)
- Instant fail (<10s) = filter rejection; delayed fail (>30s) = infra/complexity — never regenerate an instant fail unchanged [→](#instant-fail-vs-delayed-fail-the-diagnostic)
- Six slots, in order: Camera + Subject + Action + Setting + Style + Lighting; missing 3+ slots is where flags come from [→](#the-seedance-prompt-formula)
- Empirical prompt-craft laws: 50–80-word attention sweet spot (front-load the load-bearing element), name a director/lens not "cinematic", "fast" degrades motion, no negative prompts in the body, unidirectional motion chains + named camera endpoint + detail scale follows shot size [→](#prompt-craft-laws)
- Five prompt modes: Reference-Based / Continuation / Expand Shot / Edit Shot / Transformation — pick the mode before writing [→](#seedance-20-prompt-modes)
- [OFFICIAL] block scaffold for production prompts: SCENE CONTEXT → … → POSITIVE LOCKS, distributed style on standalone briefs (connected shotlists glue the compiled Style Prefix verbatim instead), FOV in degrees only, CAMERA block 3rd, cut ladder oner / CUT n / timed / freestyle [→](#official-prompt-architecture-the-block-scaffold)
- [FIELD] 13-project corpus calibration: word length scales with register (218w → 2,059w medians — the 50–80w sweet spot is single-shot-only), video briefs hand-authored (`enhance_prompt` off), Style Prefix = per-project constant compiled into home blocks [→](#field-calibration-the-13-project-production-corpus)
- [FIELD] Three "helpful-instinct" drift sources, each with a standing lock: environment invention (#1, above character drift), character-height equalization, scale drift on wides [→](#positive-locks)
- Build-safe construction for crowds/destruction/creatures: evacuated cities, contained fights ("stays at the sea surface"), the safe benchmark scene [→](#build-safe-construction-crowds-destruction-creatures)
- Extend an existing clip: attach it as a video reference + open with "The scene continues." — match source resolution AND duration; chain cap ~2 (hard 3), then re-anchor from ORIGINAL references [→](#extension-prompting-video-reference-continuation)
- **This file is Seedance 2.0.** For **2.5** — four modes incl. `video_edit` / `video_extension`, 4–30s, 30/10/10 references, in-prompt first-last frames, 720p ceiling — use `../higgsfield-seedance-2-5/SKILL.md`
- Tutorial-demonstrated patterns (reference-role vocabulary incl. VARIETY reference, SCREEN REALISM + duration-match composites, 60:30:10 grade, red-arrow prop annotation): `PRODUCTION-PATTERNS.md` in this directory
- [OFFICIAL] Feature-film pipeline (asset construction, per-scene GEO SPATIAL LAYOUT, the position-fixing first second, dialogue construction, ban dictionary, the 10–15 iteration rule, crowds / giants / thresholds): `HELL-GRIND.md` in this directory
- Performance — objective, obstacle, tactics, beats, subtext, eye life, the acting master profile: `../higgsfield-acting/SKILL.md`
- Hard engine rules (age-blind, exit-frame = cut, off-screen = nonexistent, no reflections, ≤3 tracked characters, double-contrast cuts) + high-risk shot table: `ENGINE-RULES.md` in this directory
- Reference roles: Character / Last-Frame / Environment / Prop — role determines what the prompt may re-describe [→](#reference-roles)
- Working modes: Exploration / Continuation / Bridging / Repair (distinct from prompt modes) [→](#working-modes-vs-prompt-modes-two-taxonomies)
- Layer 1 briefing vs Layer 2 production prompt — never paste Layer 1 into the prompt box [→](#two-layer-prompt-authoring)
- Native **4K** is available in `mode=std` only; `mode=fast` (Seedance 2.0 Fast) caps at 480p/720p — in Cinema Studio the model is still capped at 1080p [→](#pre-flight-linter)
- Always preflight: `python3 scripts/seedance_lint.py --preflight --model seedance_2_0 "<prompt>"` — enums come from `../../specs/model-specs.json` (fast+1080p/4K and Kling 21:9 are auto-caught) [→](#pre-flight-linter)
- 480p drafts validate the prompt, NOT the take — no seed param; pin Hero Frame + start/end frames to carry a look [→](#drafts-validate-the-prompt-not-the-take)
- ZH prompts: hard 1,800-char cap; ZH antislop list enforced by the linter [→](#multi-language-prompt-workarounds)
- Flagged prompt → rewrite playbook per linter rule, then voice pass [→](#the-rewrite-playbook)
- Repeated flags → full loop-breaker procedure + LOG THE OUTCOME (`--confirmed` / `add-quality`) [→](#when-the-user-is-already-in-a-failure-loop)
Use this skill whenever the user wants a Seedance 2.0 / Seedance Pro prompt, OR
whenever a Seedance generation has been blocked, flagged, or silently failed.
This skill's job is to stop credit waste on filter rejections.

Writes the character-performance layer of a video prompt as behavior under pressure, not displayed emotion — objective, obstacle, tactics, beats, subtext, listening, body/status/proxemics, and mandatory eye life. Produces a reusable 150–220-word acting master profile per character plus a per-scene rewrite of it, and a locked voice prompt. Use whenever a prompt needs acting, performance, or emotion direction; whenever characters read wooden, dead-eyed, or 'AI'; whenever a character must stay themselves across many shots; or when the user asks for character behavior, mannerisms, tics, a gait, or how someone reacts. Pairs with higgsfield-facs (muscle-level AU codes) and higgsfield-seedance (the prompt the paragraph goes into).

Use when the user mentions Higgsfield Canvas, a node-based or node graph workspace, an infinite board/canvas, chaining generations into a pipeline, or wants to wire prompts → images → videos across models on one surface. Covers what Canvas is, the node categories, the seven models that run inside Canvas, the named canvas patterns (Simple Seedance, Extend Video, Image Edit, StoryBoard With Elements, Long Video fan-out), the build-free / generate-paid cost model, reusable templates, assets-as-nodes, and Shared Canvas live collaboration. Also trigger on 'Higgsfield ComfyUI alternative', 'node workflow', or 'connect nodes to build a scene/campaign'.
Pre-production story-and-character development for Higgsfield projects — the upstream layer that decides WHAT to prompt before any model runs. Use when the user wants to build a character, design a world, develop a story or premise, create a character sheet / character bible / story bible, lock a visual style or 'visual DNA', plan a multi-shot narrative with consistent characters, or says things like 'help me design a character', 'build the world', 'I need a backstory', 'make this character consistent across shots', 'develop my film/series concept', or 'I keep getting generic AI characters'. Routes the locked outputs into higgsfield-prompt + the right model. Adapted from Higgsfield's official character-design framework by @vavavinca.
