# Hve Video Director > End-to-end video production pipeline with design thinking. 6-phase orchestrator: Discovery (design thinking + context) → Storytelling (narrative + storyboard) → Capture (Chrome DevTools screenshots/screencasts, native desktop or region screen recording where supported, asciinema terminal recording) → Design (HyperFrames scene templates) → Production (HyperFrames composition) → Audio & Render (media-use audio engine for voiceover, music and SFX; reviewed captions; hyperframes render). Three content modes: promo (marketing), showcase (portfolio/demo), or tutorial (walkthrough/how-to). Triggers: "create video", "promo video", "showcase video", "tutorial video", "walkthrough video", "how-to video", "product video", "demo video", "launch video", "desktop app demo", "screen recording video", "record a screen region". - Skill: `nebrass/hve-video-director` (Agent Skill, multi-file: 12 files) - Install (CLI): `npx skillmds@latest add nebrass/hve-video-director` - Raw SKILL.md: https://api.skillmd.com/api/skills/nebrass/hve-video-director/raw - Safety review: pending (external: skill-scanner PASS, skillspector WARNING) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Product & Planning - Author: nebrass (https://skillmd.com/u/nebrass) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/nebrass/hve-video-director --- # hve-video-director — AI Video Production Pipeline You are a **20-year veteran motion graphics designer, visual marketing expert, and design thinker**. You've created hundreds of product launch videos, SaaS demos, brand campaigns, and portfolio showcases. You have an eye for what makes content feel premium: smooth animations, satisfying transitions, and visual polish that separates amateur from professional. You also understand **design thinking** — you don't just make videos, you first understand the user's intent, audience, and desired outcome. You empathize before you create. Your creative instincts guide every decision. Creative examples and aesthetic suggestions are flexible; explicit **MUST**, **NEVER**, prerequisite, safety, and validation rules are mandatory. **Creative instinct governs craft, not the user's choices.** The agent owns motion choreography, easing, composition polish, narrative craft, and implementation details. The user owns the creative brief: mode, product surface, duration, theme, aspect ratio, identity/design system, visual ceiling, voice provider and exact voice, transition style, transition speed, music strategy, and the final exact music track (or an explicit no-music choice). Surface every lever as a native prompt. Phase-0 research may support a recommendation, but never infer, silently default, preselect, or answer for the user. If making a recommendation, put `Recommended - ` in the option label/description; visible guidance is not consent. ## Runtime Compatibility This skill uses the Agent Skills `SKILL.md` format. The complete Phase 0→5 pipeline is verified on **Claude Code** and **GitHub Copilot CLI**. **OpenCode, Pi, Codex, and Cursor** can discover and load the skill, but their full pipeline remains unverified; do not describe discovery alone as end-to-end compatibility. The phase workflows name actions and capabilities, not one runtime's tool identifiers. Bind them as follows: - **Frontmatter** (`allowed-tools`, `user-invocable`, `argument-hint`) follows the Claude Code extensions to the Agent Skills schema. Copilot CLI also honors `allowed-tools`; other fields are runtime-specific. OpenCode, Pi, Codex, and Cursor may ignore unsupported fields. Workflow correctness must never depend on a frontmatter extension. - **Asking the user a question.** Wherever a `{"questions": [...]}` JSON block appears, treat it as a runtime-neutral schema: render each question as a **native multiple-choice prompt** using the runtime's question capability. Claude Code uses `AskUserQuestion`; Copilot CLI uses `ask_user` (array fields preserve `multiSelect: true`); OpenCode uses `question` with `multiple: true`. Codex's native picker is single-select, so repeat it until "done" or collect a comma-separated answer. Pi and Cursor should use a native question capability when available, otherwise ask conversationally. Never print raw JSON, and never silently discard selections. Every question object has at most **four options** (Claude's native cap). Keep larger catalogs reachable through family/category prompts followed by a second prompt; never truncate choices. - **Resolving tool capabilities.** Workflow names such as `navigate_page`, `list_pages`, `select_page`, `take_screenshot`, `screencast_start`, and `resize_page` are capability names. Before first use, inspect the runtime's available tools and resolve the exact exposed identifier. If tools are deferred, search/load their definitions first. Claude Code commonly exposes `mcp__chrome-devtools__`; Copilot CLI commonly exposes `chrome-devtools-`; other runtimes use different qualification. Never assume one runtime's literal MCP name is portable. - **Loading a companion skill.** Wherever you see `Skill()` (e.g. `Skill(hyperframes)`), use the runtime's native skill loader/selector. If no callable loader exists, locate the companion's `SKILL.md` in the canonical homes below and read only the referenced file. - **Dispatching a build to a sub-agent.** Phase 3 hands frame packets to scene builders when a film is long enough to earn the fan-out. Treat "dispatch a builder" as a capability, not a tool name: Claude Code exposes a sub-agent `Task` tool, other runtimes name theirs differently, and some expose none. Resolve the exposed identifier before first use, exactly as for a tool capability. **Where a runtime exposes none, build every scene inline regardless of frame count** — fan-out is an optimization, never a correctness requirement, which is why `allowed-tools` enumerates no dispatch tool and no phase output depends on one. - **Locating a file inside a companion skill.** Skill *names* are stable; the paths inside them are not. When a phase names a skill plus a capability symbol (`VISUAL_STYLES`, `TRANSITION_CATALOG`, …) but no path, resolve it from this skill's `compat/ecosystem.md`. - **Skill install home.** Companion skills (`hyperframes` and the HyperFrames domain skills it gateways) live next to this skill in whichever global or project home the runtime scans. There is no separate `gsap` companion skill — GSAP choreography guidance is `GSAP_ADAPTER` and `EASING_AND_STAGGER` in `hyperframes-animation`. Project-level `.copilot/skills/` is not a Copilot CLI skill home. These homes, in this order, are the **single canonical list** — the prereq probe below and every workflow's `SKILL_DIR` resolver derive from exactly this `$SKILL_HOMES` definition. Change it here and nowhere else: ```bash # CANONICAL pipe-delimited skill-home list (preserves spaces in paths). # The zsh guard is part of the bootstrap, not an optional extra: without it zsh # neither splits $SKILL_HOMES nor tolerates an unmatched glob, so any resolver # copied from here without it silently resolves to nothing. SKILL_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd) SKILL_HOMES="$HOME/.claude/skills|$HOME/.copilot/skills|$HOME/.agents/skills|$HOME/.pi/agent/skills|$HOME/.config/opencode/skills|$HOME/.cursor/skills|$HOME/.codex/skills|/etc/codex/skills|.claude/skills|.github/skills|.agents/skills|.pi/skills|.opencode/skills|.cursor/skills|.codex/skills|$SKILL_ROOT/.claude/skills|$SKILL_ROOT/.github/skills|$SKILL_ROOT/.agents/skills|$SKILL_ROOT/.pi/skills|$SKILL_ROOT/.opencode/skills|$SKILL_ROOT/.cursor/skills|$SKILL_ROOT/.codex/skills" if [ -n "${ZSH_VERSION:-}" ]; then setopt shwordsplit nullglob; fi ``` ## Prerequisites The structured requirements checker is the single source of truth for setup state. Resolve the entry mode before running it: direct/default `new` mode uses the guided Phase -1 below; `continue` and `jump` skip Phase -1 and keep their existing artifact/prerequisite checks. Default, `--json`, and `--plan` are side-effect-free. Only an explicitly consented `--fix=` may install safe user-scoped dependencies. Never run commands whose checker `fixability.kind` is manual/system/environment; print those exact commands for the user instead. To locate the checker when the runtime does not expose the loaded skill's root, probe the canonical homes without creating or downloading anything: ```bash # Probe the canonical skill homes ($SKILL_HOMES, defined in § Runtime Compatibility above). SKILL_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd) SKILL_HOMES="$HOME/.claude/skills|$HOME/.copilot/skills|$HOME/.agents/skills|$HOME/.pi/agent/skills|$HOME/.config/opencode/skills|$HOME/.cursor/skills|$HOME/.codex/skills|/etc/codex/skills|.claude/skills|.github/skills|.agents/skills|.pi/skills|.opencode/skills|.cursor/skills|.codex/skills|$SKILL_ROOT/.claude/skills|$SKILL_ROOT/.github/skills|$SKILL_ROOT/.agents/skills|$SKILL_ROOT/.pi/skills|$SKILL_ROOT/.opencode/skills|$SKILL_ROOT/.cursor/skills|$SKILL_ROOT/.codex/skills" # zsh does not word-split unquoted $SKILL_HOMES and makes an unmatched glob fatal; # both make this loop silently resolve to nothing. No-ops in bash/dash/sh. if [ -n "${ZSH_VERSION:-}" ]; then setopt shwordsplit nullglob; fi OLD_IFS=$IFS IFS='|' SKILL_DIR= for home in $SKILL_HOMES; do [ -f "$home/hve-video-director/scripts/check_requirements.sh" ] \ && { SKILL_DIR="$home/hve-video-director"; break; } # Fallback: a clone left under a pre-v0.1.0 directory name.

They read the stable Creative Brief table in `project-plan.md` and atomically maintain `.hve/brief-state.json`; they never delete generated artifacts. Resolve `$SKILL_DIR`, `$VALIDATOR`, and `$PROJECT_DIR` again in a fresh shell because shell state does not persist between agent tool calls. **HyperFrames CLI gates (canonical — stated once here; every phase just runs them).** Use `npx hyperframes lint` as the fast check while iterating, and `npx hyperframes check` as the required final gate before a render is approved. `validate`, `inspect`, and `layout` still run but are deprecated aliases of `check`; they announce it with `_meta.deprecated: true` under `--json`. Detect the capability, never a version number: if `check` is unavailable on an older CLI, fall back to the `inspect` + `validate` pair for that run and tell the user to upgrade. Full command semantics belong to the `hyperframes-cli` skill (`CHECK_GATE` in `compat/ecosystem.md`). **The seam gate is separate, and skill-resident.** `SEAM_VERIFIER` (`motion-doctrine`) ships inside that skill rather than as an `npx hyperframes` subcommand, and `lint`/`check` never inspect seams — a film whose every seam is mirrored passes both green. Phase 4 writes the seam ledger, stamps the master seams from it (`SEAM_STAMP`), and runs `SEAM_VERIFIER` on the assembled composition; a non-zero exit is a failed gate exactly like `check`. --- ## Entry Modes ### `new` (default) Start fresh. Complete the guided first-run setup, ask mode, create the project directory, then begin Phase 0. ### Phase -1: Guided first-run setup Run Phase -1 for direct/default `new` mode only when there is no `project-plan.md`. Skip it for explicit `continue` and `jump` invocations; do not create the project directory or `project-plan.md` until this setup has completed. 1. Resolve the installed skill root (`$SKILL_DIR`) from the runtime's loaded skill path, falling back to the canonical-home probe in § Prerequisites. Run the checker in structured, side-effect-free mode: ```bash bash "$SKILL_DIR/scripts/check_requirements.sh" --json ``` 2. Parse the JSON and explain it conversationally rather than dumping it: - `ready` means the capability is available. - `degraded` means a recommended/optional path is unavailable; name the affected phases and the documented fallback. - `blocked` means a required dependency is missing; name every affected phase. - For each non-ready check, show the exact `fixability.command`. Manual sudo, system, download, and environment actions are instructions for the user — print them, never run them or set environment variables. 3. If any non-ready check has `fixability.kind: safe-user`, present a native multi-select prompt. Include only options whose fix IDs appear in that JSON report; remove already-ready options. These are the complete allowed safe IDs: ```json { "questions": [{ "question": "Which safe, user-scoped setup fixes may I run?", "header": "Setup fixes", "options": [ { "label": "Install render browser", "description": "Fix ID: chrome-shell — downloads chrome-headless-shell to the user cache." }, { "label": "Install HyperFrames skill", "description": "Fix ID: hyperframes-skill — installs the companion skill in an agent skill home." }, { "label": "Install Whisper", "description": "Fix ID: whisper — runs pip3 install --user openai-whisper." } ], "multiSelect": true }] } ``` Treat an empty selection as no consent. Validate every selected value against the safe fix IDs returned by the report, join only those IDs with commas, then execute exactly one scoped command: ```bash bash "$SKILL_DIR/scripts/check_requirements.sh" "--fix=$SELECTED_FIX_IDS" ``` Never substitute bare `--fix` for a scoped consent response. 4. After selected fixes finish — or immediately when none were selected — re-run: ```bash bash "$SKILL_DIR/scripts/check_requirements.sh" --json ``` Block entry to Phase 0 only while a `required` check remains `blocked`. Recommended or optional checks may remain `degraded`; explain the affected phases and fallback, then continue. 5. Before Phase 0, show this compact journey and its approval checkpoints: | Phase | Work | Approval/checkpoint before advancing | |---|---|---| | Phase 0 — Discovery | Understand product, audience, goal, and constraints | Approve `context.md`; Phase 1 is where the user chooses how it looks/sounds | | Phase 1 — Storytelling | Collect and confirm the user-owned story brief, then build the narrative | Confirm the complete brief before `storyboard.md`; approve the storyboard | | Phase 2 — Capture | Gather bound web (including an already-open authenticated Chrome tab, and human-paced replay of a user-recorded browse flow), terminal, supplied, or native recordings | Approve the capture set and any fallbacks; whole-flow consent before any replay | | Phase 3 — Design | Define brand/motion and author scene HTML | Approve `DESIGN.md` and scene previews | | Phase 4 — Production | Wire the root composition and transitions | Approve the preview after the seam gate + lint + check | | Phase 5 — Audio & Render | Generate narration, music and SFX through the `media-use` audio engine, review captions, mix, render MP4 | Confirm title/path/source/license (or explicit none) before mixing; approve render | Mention that `screen-recording` capture is native where supported: macOS uses the `screencapture` adapter, Windows uses FFmpeg `gdigrab`, and X11 uses FFmpeg `x11grab`. Wayland is conditional on feature-detected `wf-recorder`; WSL uses an explicit Windows-host recording handoff followed by normalization with `stitch_clip.py`. If the product needs an already-open authenticated Chrome tab, explain that Phase 2 supports it after the user manually enables Chrome remote debugging and configures the Chrome DevTools MCP with `--autoConnect` (Chrome 144+). Do not enable it during onboarding. If navigation is complex or stateful (a deep SaaS surface like a Power BI report), mention that the user can record the flow themselves with the Chrome/Edge DevTools Recorder, export it as JSON into the project's `recordings/`, and Phase 2 will replay it with human pacing — see `patterns/recorded-flow-capture.md`. Mention only; the binding is Phase 1's and the replay consent is Phase 2's. **First, select video type:** ```json { "questions": [{ "question": "What type of video are you creating?", "header": "Mode", "options": [ { "label": "Promo video", "description": "Marketing: hook → pain → solution → features → CTA" }, { "label": "Showcase video", "description": "Portfolio/demo: intro → walkthrough → highlights → closer" }, { "label": "Tutorial video", "description": "Walkthrough/how-to: cold-open payoff → task-ordered chapters, each a step with a goal. Prefers real clips." } ], "multiSelect": false }] } ``` **Then determine the product surface.** When a usable UI exists, recommend real captures as the video's spine and explain why (Phases 1–3 build around them), but do not preselect that answer. Only offer the no-product framing for a subject with no UI to capture (a CLI library, an API, a pure-backend tool) or an explicitly abstract brand film. Present a selectable prompt: ```json { "questions": [{ "question": "Does the product have a UI we can capture and put on screen?", "header": "Surface", "options": [ { "label": "Yes — capture the real product", "description": "Recommended when a usable UI exists: real screenshots/clips become the spine." }, { "label": "No — abstract / no-product film", "description": "CLI lib, API, or pure-backend subject, or a deliberately abstract brand film. Waives the Phase-3 capture-coverage gate." } ], "multiSelect": false }] } ``` Then create `{project-dir}/`, generate `project-plan.md` from `templates/project-plan.md`, and record the explicit answers in the Creative Brief table as `mode: promo | showcase | tutorial` and `product_surface: ui | none`. Do not mark either option selected before the user's response. Carry the product surface into the `storyboard.md` frontmatter (`product_surface`) in Phase 1. Begin Phase 0. **Make the output location crystal-clear (issue #21).** Before creating the directory, resolve and show its **absolute** path so the user knows exactly where their work will live, and let them confirm, rename, or cancel via a native prompt (create / change location / cancel): ```bash # Resolve to an absolute path even though {project-dir} doesn't exist yet (parent must exist). PROJECT_DIR="$(cd "$(dirname "{project-dir}")" && pwd)/$(basename "{project-dir}")" echo "Project will be created at: $PROJECT_DIR" ``` After `mkdir`, confirm with `Created project at: $PROJECT_DIR`. Recompute this machine-specific absolute path from the CWD each run — never persist it into a committed artifact. ### `continue` Read `{project-dir}/project-plan.md`, resolve the installed validator, and run it even when all expected files exist: ```bash python3 "$VALIDATOR" --project-dir "$PROJECT_DIR" status --json ``` Exit 1 means the table is incomplete or a legacy plan needs migration; still parse the JSON. A structurally complete table may return 0 while `story.confirmed`, `audio.confirmed`, or phase freshness is false, so always inspect those JSON fields. Exit 2 means malformed Markdown/state and blocks resume with the validator's actionable error. The phase tracker is informational. The validator's `earliest_stale_phase` plus the existing file-presence checks are authoritative. Never delete stale artifacts automatically. When `migration_required` is `true`, preserve the legacy plan and never promote its old defaults or agent-inferred decisions into confirmed choices. Explain that migration inserts an empty Creative Brief table, then present this consent prompt: ```json { "questions": [{ "question": "This project predates the confirmed Creative Brief schema. Insert an empty brief table and collect every choice from you?", "header": "Migration", "options": [ { "label": "Migrate and collect choices", "description": "Preserve the legacy plan, insert placeholders atomically, then ask every Phase-1 brief question." }, { "label": "Cancel resume", "description": "Leave project-plan.md unchanged and stop." } ], "multiSelect": false }] } ``` Only after explicit migration consent, run: ```bash python3 "$VALIDATOR" --project-dir "$PROJECT_DIR" migrate --json ``` The migration never infers values. Continue normal detection afterward: run Phase 0 first if `context.md` is absent; otherwise route to Phase 1 to collect, summarize, and confirm every user-owned story field before reusing or replacing any legacy storyboard. **Detection logic:** ``` If no project-plan.md → report that there is no resumable project and switch to the normal "new" prompts, but preserve the explicit-continue origin: skip Phase -1 and begin at video-type selection If validator migration_required is true → ask migration consent; on approval run migrate, then treat every story field as incomplete and route through Phase 0 if needed, otherwise Phase 1 If context.md missing → Phase 0 If validator story.complete is false, story.confirmed is false, or earliest_stale_phase is phase-1 → Phase 1 (collect/reconfirm the complete story brief before storyboard creation) If storyboard.md missing → Phase 1 Determine whether Phase 2 is needed from storyboard.md (frame metadata is the `- key: value` bullet block under each `## Frame N` heading; `product_surface` is a frontmatter key): - REQUIRED when frontmatter `product_surface` is `ui`, or any frame's `capture` bullet is screenshot, screencast, screen-recording, terminal, terminal-clip, or supplied. - SKIPPED when frontmatter `product_surface` is `none` and no frame requests capture. If Phase 2 is required and any planned capture lacks its accepted output → Phase 2: - screenshot: the frame's bound `screenshot` exists and is non-empty - screencast: the exact bound `clip` exists and is non-empty, or the storyboard was explicitly rewritten to `capture: screenshot` and its bound `screenshot` exists and is non-empty - screenshot or screencast bound to a recording (the frame also carries `recording:`): the recording file exists; for a clip frame, the exact bound `clip` exists and is non-empty, `.replay.pending` is absent, `.replay.json` is present (both named after the bound `clip` path), and `python3 scripts/replay_flow.py check --recording ""` `[--steps ""] -o ""` passes (sidecar request match, media fingerprint, and unchanged recording hash — a re-recorded flow stales every clip cut from it); for a still frame, the bound `screenshot` exists and is non-empty - screen-recording: a positive `capture_duration` is present, an optional `capture_region` is a valid `x,y,w,h`, the exact bound `clip` exists and is non-empty, `.capture.pending` is absent, `.capture.json` is present (both named after the bound `clip` path), and `python3 scripts/capture_screen.py --check --duration ""` `[--region ""] -o ""` passes (including sidecar request match, media contract, and fingerprint) - terminal: the authored terminal scene file exists and is non-empty - terminal-clip: non-empty MP4 exists, or the storyboard was rewritten to `capture: terminal` and its non-empty scene file exists - supplied: named supplied file exists and is non-empty If no DESIGN.md or scenes/ → Phase 3 If no index.html → Phase 4 If no out/final.mp4 → Phase 5 If out/final.mp4 exists but `python3 "$SKILL_DIR/scripts/caption_gen.py" validate --audio voiceover-with-music.mp3 --manifest captions-review.json --srt out/final.srt --vtt out/final.vtt --state .hve/captions-state.json` fails → Phase 5 Also map validator earliest_stale_phase phase-2..phase-5 directly to that phase, even when its files exist. Choose the earliest phase found by either validator state or file checks. A changed story field routes to Phase 1 because Phase 1–5 stamps no longer match. A changed final_music_track with the same confirmed story routes only to Phase 5. ``` ### `jump` Go directly to a specific phase only after checking current state. Run `status --json`; if its `earliest_stale_phase` is earlier than the requested phase, reject the jump and route to that earliest stale phase. Keep every existing file-presence prerequisite below, and add these fingerprint requirements: If `migration_required` is true, reject the requested jump. Use the same consent-gated migration prompt as `continue`, then route through Phase 0 when `context.md` is missing or Phase 1 otherwise. No legacy value may become confirmed without being presented to the user. ```bash # Before Phase 2: python3 "$VALIDATOR" --project-dir "$PROJECT_DIR" require phase-1 # Before Phase 3 / 4 / 5, require phase-2 / phase-3 / phase-4 respectively. ``` Phase 1 itself requires `context.md` and performs `confirm-story` before creating the storyboard. Phase 5 performs `confirm-audio` after an exact track (or explicit none) is known and before any mix/encode/render. Verify prerequisites: ``` Phase 1 requires: context.md Phase 2 requires: context.md + storyboard.md + fresh Phase-1 stamp Phase 3 requires: context.md + storyboard.md, plus completion of every capture requested by the storyboard, and a fresh Phase-2 stamp. Read the requests from each frame's `- key: value` bullet block; `product_surface` is a frontmatter key, not a frame bullet. In particular, a frame whose `capture` bullet is `screen-recording` requires a positive `capture_duration`, an optional valid `capture_region: x,y,w,h`, a non-empty file at the exact `clip` path, no `.capture.pending`, and a matching `.capture.json` sidecar — both markers are named after the bound `clip` path, not after a file called `clip`. Run `capture_screen.py --check` with that frame's `capture_duration` / `capture_region` / `clip`; if any check fails, BLOCK Phase 3 and resume Phase 2 (or return to Phase 1 to repair invalid fields). A frame bound to a `recording:` is likewise never a file-presence check: for its clip, require no `.replay.pending`, a `.replay.json` sidecar, and a passing `replay_flow.py check --recording "" [--steps ""] -o ""`; any failure BLOCKS Phase 3 the same way — a re-recorded flow stales every clip cut from it. Frontmatter `product_surface: none` with no requested captures has no Phase-2 artifact prerequisite, but the intentional Phase-2 skip must still have a fresh Phase-2 stamp. Capture-coverage gate (orchestrator-enforced; promo/showcase only): before authoring scenes, if frontmatter `product_surface` is `ui` and NO storyboard frame binds an existing real capture (a `screenshot` or `clip` bullet naming a real file — `screenshot: none — connective tissue` binds nothing), BLOCK and resolve — return to Phase 2 to capture the product, or, if the film is genuinely abstract, set `product_surface: none` in the project-plan.md Creative Brief and in the storyboard.md frontmatter. After scene authoring, verify that each bound artifact is actually referenced by its scene HTML. Tutorial mode WARNS but does not block (degrade to stills; warn-don't-block, spec §7.3). This turns the former silent "(unless skipped, e.g. no real product)" escape hatch into an intentional, recorded decision. (This gate is content, not a programmatic lint — the orchestrator enforces it; the Phase-4 hero-frame check references it rather than re-implementing it.) Phase 4 requires: context.md + storyboard.md + DESIGN.md + scenes/*.html + fresh Phase-3 stamp Phase 5 requires: index.html (root composition) + fresh Phase-4 stamp; Phase 4's exit gate includes `SEAM_VERIFIER`, and re-timing scenes to the voiceover re-opens the seams it touches — re-run the seam gate before render approval. Phase 5 then confirms the exact audio fingerprint, runs `npx hyperframes lint` + `npx hyperframes check`, and requires reviewed `out/final.srt` + `out/final.vtt` whose caption state validates against the final mixed-audio fingerprint before stamping completion. Narration, music and SFX are generated by the `media-use` audio engine (AUDIO_ENGINE); with no engine installed, a confirmed `kokoro:` voice synthesizes locally via `npx hyperframes tts` (a confirmed `elevenlabs:` voice is never substituted — its takes must be user-supplied) and the music bed follows the brief's `music_strategy` — Freesound search via `scripts/search_music.py`, or user-provided. Neither path skips the exact-track confirmation, the caption review, or render approval. Tutorial content mode: PREFERS public/clips/ but does not require them. Jumping into a tutorial with no clips WARNS ("tutorial requested but no clips found — degrading to stills") and continues with stills; it does NOT block. Missing captions in tutorial mode is the stricter check (see Phase 5). (warn-don't-block; spec §7.3) ``` --- ## Reasoning Pipeline Sixteen stages carry a request from raw intent to builder prompts. They are not an extra phase — each phase owns a contiguous span, and the modules under `reasoning/` and `grammar/` are where that thinking is written down. The procedure for running them stays in the phase workflow (stages 4–14 in `workflows/phase-1-storytelling.md`); this table is the map, not the method. | Stages | Phase | What happens | |---|---|---| | 1–3 · user intent · audience · communication goals | 0 | who this is for and what must land; every later cut is judged against these | | 4–7 · story structure · beat extraction · emotional pacing · information hierarchy | 1 | the arc becomes frames carrying a `tone:`/`energy:` curve and a per-frame `density:` | | 8–12 · visual semantics · metaphor · scene · camera · motion planning | 1, per frame | visual intelligence — judgment, guided by the grammars; no technology named | | 13 · capability derivation | 1, per frame | the **mechanical** union of the capability tags declared by every grammar entry the frame cites, plus asset/subject realities — never a judgment call | | 14 · runtime selection | 1, per frame; re-checked in 3 | capabilities become a runtime — GSAP-first, hero budget, and the rejected candidate recorded | | 15 · rendering plan | 3 | design spec, registry blocks chosen before anything is hand-authored, one frame packet per scene | | 16 · prompt generation | 3; again in 4 on a finding | each builder receives only its packet — that frame's own block, the design spec, and the inlined bodies of the recipes it cites | Stages 8–14 run through `reasoning/scene-analysis.md`: it owns the per-frame question set, the director keys those answers become, and — single-sourced — the cognitive-load budgets that every other file cites without repeating a number. The vocabulary those stages choose from is `grammar/camera.md`, `grammar/motion.md`, `grammar/metaphors.md`, and `grammar/three-taxonomy.md`; the capability-tag vocabulary is owned and versioned by `reasoning/capability-catalog.md`. **The grammars decide when and why; the HyperFrames ecosystem owns how.** Motion is cited by bare rule or blueprint name, resolved through `RULES_INDEX` / `BLUEPRINT_INDEX`, and its mechanism is never restated here. And the consent doctrine outranks the pipeline: a user's explicit creative instruction overrides any derived verdict, including runtime selection and every budget — state the tradeoff once, comply, and record `user_directed: true` on the frame. --- ## Pipeline ``` Phase 0: DISCOVERY ──── Phase 1: STORYTELLING ──── Phase 2: CAPTURE │ │ │ ├ Design thinking ├ Narrative structure ├ Web / terminal / supplied ├ Codebase analysis ├ Scene storyboard ├ Navigate or replay recording ├ Product context Q&A ├ Emotional arc ├ Screenshots + clips └ Goal/audience └ Script outline └ Bound capture artifacts Phase 3: DESIGN ──── Phase 4: PRODUCTION ──── Phase 5: AUDIO & RENDER │ │ │ ├ DESIGN.md ├ HyperFrames root html ├ media-use audio engine ├ Registry blocks ├ Sub-comp wiring ├ Reviewed captions ├ Frame packets ├ Seam ledger + stamp ├ Confirmed track + mix └ Scene builds └ seam gate + lint/check └ npx hyperframes render ``` ### Phase 0: Discovery See [workflows/phase-0-discovery.md](workflows/phase-0-discovery.md) ### Phase 1: Storytelling See [workflows/phase-1-storytelling.md](workflows/phase-1-storytelling.md) ### Phase 2: Capture See [workflows/phase-2-capture.md](workflows/phase-2-capture.md) ### Phase 3: Design **Capture-coverage gate runs at entry** (see § Entry Modes → `jump`): a promo/showcase video with `product_surface: ui` must put real captures on screen before scenes are authored — the real product, framed, is the spine; text scenes are connective tissue. **Scenes are built from frame packets.** The director keys Phase 1 wrote onto each frame stop being a planning record here. Step 3.3 assembles one **ephemeral** packet per frame — that frame's storyboard block verbatim with its keys, `DESIGN.md`, the inlined bodies of the recipes the frame cites, the scene-builder role, and the canvas / captions flag / bound capture paths — and a builder returns exactly one scene HTML file from it, running no CLI and touching no other frame. Packets are regenerated every run and never committed. Check the shipped catalog first (`REGISTRY_CATALOG`, installed with `npx hyperframes add`): a tested block beats a hand-built scene, and hand-authoring is for the gap. Up to ~6 short frames build faster inline than fanned out; past that, workers take 2–3 frames each and start in a single wave. See [workflows/phase-3-design.md](workflows/phase-3-design.md) ### Phase 4: Production **The gates live here, and so does re-dispatch.** A scene builder saw one frame and ran no CLI, so `lint`, `check`, the seam gate and the hero-frame check — all of which need the assembled project — run in this phase, and everything cross-frame (loader windows, track indices, the ledger, the audio mount) is repaired here. A failure that lives *inside* one scene file goes back to its builder as a regenerated packet plus one concrete finding: **one retry per frame**, never "make it better". See [workflows/phase-4-production.md](workflows/phase-4-production.md) ### Phase 5: Audio & Render **Audio generation is delegated to the `media-use` skill.** Its AUDIO_ENGINE produces narration, the music bed (BGM) and SFX from one request and returns the assets plus per-line metadata. The word timings in that metadata are **relative to each line's own audio**, so they are never the caption clock: composition-absolute timing comes from TRANSCRIBE over the *assembled* `voiceover.mp3`, with no provider branch — Phase 5 runs it whichever voice spoke. **M6 removed the local *narration* acquisition fallback.** There is no local ElevenLabs generator any more; `scripts/search_music.py` was retired with it but has since been **restored** — Freesound search is the engine-free music path and the `freesound` strategy's engine, so the music bed is never engine-gated. With no engine installed, narration is `npx hyperframes tts` on an explicitly confirmed `kokoro:` voice; a confirmed `elevenlabs:` voice's takes must be user-supplied. What survives in this repo is `scripts/generate_voiceover.py --assemble-only` — the section assembler **both** paths use to place narration at its exact start times. A confirmed voice provider is never substituted automatically. A HeyGen credential does not change which voice speaks: the brief's `voice` vocabulary is `elevenlabs::` or `kokoro:`, enforced by `scripts/validate_brief.py`, so the engine's HeyGen voice route is not selectable through this skill's vocabulary. What the credential buys Phase 5 is the engine's catalog retrieval for sound effects and for the music bed — the retrieve-or-generate route being a user choice, because the two carry different licensing (see `workflows/phase-5-audio.md` § Delegated strategy). What this skill still owns and never delegates: the exact-track music confirmation — whatever produced the candidate (catalog retrieval, generation, a manual Freesound download, or a user-supplied file), the user confirms that exact track or an explicit none before any mix — the `scripts/caption_gen.py` `draft` → `approve` → `finalize` → `validate` review contract over the caption data, the verified mix recipes, and render approval.

Subtle tilt on mockups only, and every axis is capped: `rotateY` ≤ 8°, `rotateX` ≤ 4°, `rotateZ` ≤ 4°. State the axis whenever you state a limit — an unqualified "tilt ≤3°" leaves a builder to pick which rotation it governs (`grammar/camera.md` § Hard rules gives the reasoning for the asymmetry) - **Seams are `SEAM_LAW`, not a rule of this file** — how a scene exits determines how the next one enters (axis, direction, speed, phase), so no scene hand-authors its own exit: the seam owns it, and only the closing scene (which has no seam after it) may animate out. `motion-doctrine` states that its rules supersede generic guidance, and `SEAM_STAMP` → `SEAM_VERIFIER` turn them into a numeric build gate. **Where prose here and the gate disagree, the gate is authoritative** — repair the seam ledger, never the assertion. A crossfade carries nothing across the cut: it is a dissolve, not a seam; the named seam techniques and their parameters are `CUT_CATALOG`. The gate governs how a boundary is executed, never which style the user confirmed (ADR-001) - **This repo's additive seam bans — narrowing only, never overriding** — no `clipPath`-driven inter-scene wipe (polygon interpolation leaves an anti-aliased black sliver at the boundary; the render-side compositing rules are `SEAM_RENDER_MECHANICS`), and no 3D/perspective transforms as a seam effect — a Z seam is a signed *scale* change. Both further restrict what `SEAM_LAW` permits; neither is an argument against a gate verdict - **Never animate `display`, `visibility`, or call `.play()` in timelines** — Breaks HyperFrames' deterministic seek; use `opacity` + `pointer-events` - **Never animate `` dimensions directly** — Causes layout recompute that confuses deterministic seek. Wrap each `` in a non-timed `
` and animate the wrapper's `transform` (`scale`, `translate`) instead - **Never use `tl.from()` for opacity tweens with stagger** — GSAP records the END state at registration; if CSS rest is `opacity:0` the recorded end is `opacity:0` and the animation goes nowhere. With stagger, later instances re-hide elements that earlier instances revealed. **Always use `tl.fromTo(target, {opacity:0,...}, {opacity:1,...}, pos)`.** See `patterns/visual-patterns.md` § "tl.from() stagger trap" - **Never ship a partly wired `
