description

Produce a faceless YouTube-style video (hand-drawn doodle / simple-illustration channels like Zen, Nick Invest) end-to-end from a single topic. ASKS FACT-vs-STORY mode first (non-fiction educational vs fiction storytelling) and branches the whole run — built to serve multiple clients/channels, not one fixed format. Reverse-engineers a proven reference video's script format, writes a new script in that format, generates an ElevenLabs voiceover with timestamps, creates one styled Artlist (AI Toolkit) image per timestamp, and stitches everything with FFmpeg — fully automated, no human recording. Use when the user says "faceless video", "/faceless-video", "doodle video", "make a YouTube short/long-form in the Zen style", or wants an organic faceless-channel content piece. Composes with video-distribution-strategist (channel/launch) and video-director (when motion/edit polish is wanted instead of stills).

Faceless Video Pipeline

Build a faceless-channel video as a deterministic 4-stage pipeline. Source teardown: ~/2nd Brain/2nd Brain/Wiki/research-faceless-youtube-claude-code-pipeline-2026-06-26.md.

Hard rules (platform risk + quality)

1. Voice = ElevenLabs Voice Artist (Phill's paid plan), NOT a human recording. The source video's "AI voice gets you banned" fear is WRONG — see the YouTube disclosure policy in Sources/youtube-synthetic-content-disclosure-policy-2026-06-26.md. The real rule: YouTube's altered/synthetic disclosure is required for AI music, a synthetic voice that is NOT the creator's own clone, or realistic AI of real people/places/events — and is NOT required for animation/doodles. Disclosure is costless (no audience/monetization hit), so default to YES whenever the video has AI music or a non-self synthetic voice (our pipeline always does). Set it in YouTube Studio → Attributes → "AI use" → Yes. Set "Made for kids" = Yes only for child-directed content (STORY/childcare).
2. One style token, every image. Lock a single style description up front; every generated image carries it verbatim so the channel stays visually consistent.
3. Mode-appropriate authority (see Stage 0 switch). FACT/non-fiction: cite real studies / dates / stats, research before writing, accuracy-gate the claims. STORY/fiction: invented narrative; authority is emotional resonance, not facts; gate for age- and brand-appropriateness instead (e.g. childcare = gentle, safe, age-suitable). NEVER present fiction as fact or invent "facts" in fact mode.
4. Stills + voiceover, not motion graphics. This is the doodle-channel format. If the user wants animation/edit polish, hand off to video-director instead.

Substrate — IMPORTANT distinction

The source video uses Higgsfield (Claude Code MCP). We do NOT use Higgsfield. Phill's image platform is Artlist (artlist.io, AI Toolkit), driven in-browser via browser-harness. NB: "artist.io" is a typo for artlist.io.

• Image gen (primary): Artlist AI Toolkit at toolkit.artlist.io/image-video-generator?mode=image (model Nano Banana 2, 16:9 / 2K). Dogfood-proven mechanics in Stage 3.
• Image gen (fallback): mcp__margot__image_generate (also Nano Banana 2) — unattended test runs only. Never Higgsfield.
• Voiceover: ElevenLabs TTS via REST API. Key + default voice in ~/.hermes/.env (ELEVENLABS_API_KEY, ELEVENLABS_VOICE_ID) — resolve programmatically, never paste. No human recording.
• Transcript pull: yt-dlp. Timestamps: ElevenLabs alignment (primary) or whisper-cli (fallback). Stitch: ffmpeg.

Working folder

Create ~/faceless-video/<topic-slug>/ and keep every artifact there: reference-format.md, script.md, voiceover.mp3, transcript.json, images/NN.png, final.mp4.

Stage 0 — MODE SWITCH (ASK FIRST, before anything else)

The engine serves opposite jobs across clients/applications, so the FIRST question every run is:

"Is this a FACT (non-fiction) or STORY (fiction) script?" Record mode in the working folder (mode.txt). It branches the whole run:

	FACT (non-fiction)	STORY (fiction)
Use case	educational product, explainers, "did-you-know"	childcare tales, parables, bedtime/brand stories
Reference lane	hook + 3-pillar body + payoff	character → flaw → journey → lesson → resolution
Authority	researched real studies/stats/dates; accuracy-gate	emotional resonance; age/brand-appropriateness gate
Hard rule	never invent facts	never present fiction as fact
YouTube disclosure	AI-use = Yes (AI music/voice present)	AI-use = Yes + Made for kids = Yes (child-directed)

If the caller already implies the mode (e.g. "a childcare story for my wife" → STORY; "explain X for my product" → FACT), confirm it in one line rather than re-asking. Default reference handling, script template, and gating all follow from this switch.

Stage 0b — Style token (once per channel, then reuse)

Ask the user for 3–5 reference screenshots of the target visual style. Prompt the analysis:

"Analyse this image's visual style for an AI image generator. Give (1) a short positive style description I can paste as a prompt, (2) a list of negative prompts to prevent drift toward polished/realistic output. Focus on style only, not subject matter." Save the result as style-token.md in the channel root (reused across all videos for that channel).

Stage 1 — Script (branches on Stage 0 mode)

1. Ask for the topic and a proven reference video URL in the chosen mode's lane (a fact channel for FACT, a story channel for STORY — don't cross lanes).
2. Pull the reference transcript: yt-dlp --write-auto-sub --sub-lang en --skip-download --sub-format vtt -o 'ref-%(id)s.%(ext)s' '<URL>'. Clean the .vtt (strip timestamps/tags, dedupe rolling auto-sub lines).
3. Decompose into a reusable template, per mode:
   • FACT: hook (the micro-beats), intro/promise, the 3-pillar body, transition sentences, total length.
   • STORY: protagonist + one shared flaw, the ache, inciting incident, journey, a SHOWN demonstration (not told), one quotable wisdom line, internal realisation, carry-forward close. Save as reference-format.md.
4. Write a NEW script on the topic in that template. FACT: first run the source-ingest skill to pull credible Tier 1–2 data into the vault Sources/ library, then write the script citing only those stored sources and accuracy-gate every claim against them. STORY: invent freely, age/brand-gate. Output a CLEAN script (no scene directions) to script.md.
5. Confirm the script with the user before generating the voiceover.

Stage 2 — Voiceover + timestamps (ElevenLabs, automated)

1. Generate the voiceover from script.md via the ElevenLabs with-timestamps endpoint (returns audio + character alignment in one call): curl -s -X POST "https://api.elevenlabs.io/v1/text-to-speech/$ELEVENLABS_VOICE_ID/with-timestamps" -H "xi-api-key: $ELEVENLABS_API_KEY" -H "content-type: application/json" -d '{"text":"<script>","model_id":"eleven_multilingual_v2"}' → save base64 audio to voiceover.mp3 and the alignment to transcript.json.
2. Derive per-phrase/sentence timestamp segments from the alignment — each segment becomes one image beat. (Fallback if alignment is unusable: whisper-cli -f voiceover.wav -ml 1 --output-json -of transcript after ffmpeg -i voiceover.mp3 voiceover.wav.)
3. Voice is per-channel/client, not fixed — pick the ElevenLabs voice that fits the mode/brand (e.g. warm, gentle storyteller for childcare fiction; clear, authoritative voice for an educational fact product). Pass that voice_id instead of the default in ELEVENLABS_VOICE_ID. Browse the user's ElevenLabs voice library when choosing.
4. No human pause — Stage 2 runs unattended.

Stage 3 — One image per timestamp (Artlist AI Toolkit, browser-proven)

Per beat: scene prompt + locked style token verbatim. Drive Artlist via browser-harness (needs Phill's Chrome logged in; Way-1 remote-debugging enabled). Hard-won mechanics:

1. Open toolkit.artlist.io/image-video-generator?mode=image. Prompt is a [contenteditable=true] div; the Generate button matches innerText Generate. Default settings are already 16:9 / 2K / 1 image (good).
2. Per image: snapshot existing generated UUIDs → click box, document.execCommand('selectAll'), type_text(prompt) → click Generate → poll until loader text (on its way|Almost ready|Generating) clears AND a new UUID appears.
3. Result lives at ai-toolkit-generations.imgix.net/...png?...&s=<sig>. Extract UUID with the GENERIC regex [0-9a-f]{8}-[0-9a-f]{4}-...{12}\.png (filename prefix varies: image-<uuid> OR -t-e-x-t_-t-o_-i-m-a-g-e-<uuid>). Download the EXACT src — rewriting any imgix param (e.g. w=) breaks the signature → 403.
4. Go ONE AT A TIME. Rapid bursts queue/throttle and the grid view virtualizes the DOM, both of which break new-UUID detection. If a generation completes after the poll window, salvage it from the grid (download distinct unmapped UUIDs, montage, map visually). Fallback (unattended only): mcp__margot__image_generate — saves <save_as>.jpg, account for the extension.

Stage 4 — Stitch

Build an FFmpeg concat that holds each image for (next_start - this_start) seconds and muxes the voiceover:

1. Generate a concat list with per-image durations from the timestamps.
2. ffmpeg -f concat -safe 0 -i list.txt -i voiceover.wav -c:v libx264 -pix_fmt yuv420p -c:a aac -shortest final.mp4
3. Recommend 2K source images for real uploads (low-res only for test runs).

Stage 5 — Finalise (for a real upload, not test runs)

Turn the raw stitch into a finished deliverable:

• 1080p — render the concat scaled/padded to 1920:1080 (white pad blends the sketchbook bg), crf 19.
• Fades — fade=t=in:st=0:d=0.6:color=white and fade=t=out over the last ~0.8s. Keep hard cuts on the beats between images (on-style — do NOT crossfade).
• Music bed — generate a calm track via Artlist AI Music (toolkit.artlist.io/music-generator?mode=music, Lyria 3; same browser flow as images, result is a signed .wav at cms-toolkit-artifacts.artlist.io/...music-<uuid> — download EXACT src). Mix UNDER the VO: volume≈0.13 (~−18 dB), afade in 1.5s / out ~1.8s, amix=inputs=2:normalize=0. Verify with volumedetect: overall peak < 0 dB (no clip), music mean ~15+ dB below VO.

Output

final-1080p-music.mp4 (the deliverable) + a reusable style-token.md. Report the path and per-stage artifacts. For publishing/channel strategy hand off to video-distribution-strategist; remember the synthetic-content disclosure on upload.
