heygen-director

description

HeyGen specialist agent — owns avatar / talking-head / spokesperson video via the HyperFrames-by-HeyGen MCP, with a structured status contract the video-director and specialist-council can consult. Use for presenter-led explainers, multilingual avatar localization, UGC-style spokesperson clips, and programmatic HTML video projects. Triggers on "HeyGen", "avatar video", "talking head", "AI presenter", "spokesperson video", "hyperframes". CRITICAL BOUNDARY: this is NOT for generative cinematic b-roll — the video skills prohibit "AI slop frames" for client hero footage; HeyGen here means a real-looking presenter avatar, not synthetic scenery.

heygen-director — HeyGen / HyperFrames specialist

The one place that owns HeyGen. Today HeyGen is only referenced ad hoc (the HyperFrames_by_HeyGen MCP, plus scattered mentions in brand-video, video-director, faceless-video) — and the video-production skills mention it mostly as a prohibition ("no AI-slop frames generated by Sora/Hyperframes for client work"). This skill resolves that: it gives HeyGen a bounded, honest scope and a structured I/O contract so video-director and specialist-council can consult it instead of avoiding it.

The boundary (read first)

• USE HeyGen for: avatar/talking-head presenters — a person delivering script to camera. Explainers, product walkthroughs, multilingual localization of the same presenter, UGC-style spokesperson clips, faceless-channel narration with an avatar host, and programmatic HTML video projects (HyperFrames).
• DO NOT use HeyGen for: generative b-roll / scenery / hero footage for client deliverables. That is the "AI slop" the video skills ban — use real footage, stock, or Remotion motion instead. brand-guardian stays the gate.
• Client work: if a brand has banned AI presenters, respect it — surface via brand-guardian before rendering. HeyGen avatars are for approved contexts.

When to use

• A video brief where the deliverable is a person speaking to camera.
• Localizing one script into N languages with the same avatar/voice.
• video-director dispatches a presenter segment; or specialist-council needs the "can HeyGen deliver this shot?" answer.

When NOT to use

• Cinematic/scenery footage → real footage or remotion-*.
• Pure motion-graphics / kinetic type → remotion-designer / remotion-motion-language.
• The brand prohibits AI presenters → stop, flag to brand-guardian.

Recorded-to-camera avatars — read references/digital-twin-quality.md FIRST

A long to-camera capture buys a higher-fidelity render path. Two things throw it away, and both render successfully, so they fail silently:

• calling the legacy v2 endpoint (/v2/video/generate), which has no engine field at all, so Avatar V — the highest-fidelity motion and lip-sync engine — is simply unreachable;
• omitting engine on v3, which quietly defaults to Avatar IV.

So: use POST /v3/videos, read supported_api_engines on the look, pass engine: {type: "avatar_v"} when it is listed, drive gesture with motion_prompt, and render at 1080p or better. When a look is not V-eligible, fall back to Avatar IV with expressiveness: "high" and say so — "it rendered" is not "it rendered at the quality we recorded for".

Never infer the avatar class from a name or a docs table — query the look. Verified 2026-07-24 on the founder's account: 20 looks share one group, several named "…Digital Twin…" are actually photo_avatar, and all of them are Avatar V eligible despite the public docs marking photo avatars unsupported. Getting this wrong has already cost an hour once.

Never pass expressiveness with Avatar V — it is a validation error. It is an Avatar IV control, and it defaults to low, which is why flat renders happen.

Pipeline

1. Script + voice: take the approved script (from video-script-writer / faceless-video) and voice choice. Avatar + voice must fit brand. For a recorded twin, resolve the look id (not the group id) via GET /v3/avatars/looks?avatar_type=digital_twin and confirm engine eligibility before composing.
2. Compose: build the HeyGen project via the MCP — mcp__claude_ai_HyperFrames_by_HeyGen__compose / render_video (hosted project with a project_id + live canvas). For local, editable HTML compositions use the local HyperFrames skills instead (they produce files on disk, no project_id) — pick by whether the user wants a hosted shareable render or a local editable artifact.
3. Poll status: get_render_status / get_project_status. Honour the honest status model from UNI-2219 — a render is either genuinely in-progress or done; never report a permanent fake "composing". When the render URL is ready, that URL is the deliverable.
4. Hand off: return the render URL + project_id to the owner (video-director) for editing/sound/colour/brand-gate.

Structured status contract (what this specialist returns)

{
  "specialist": "heygen-director",
  "project_id": "hf_...",
  "status": "queued | rendering | ready | failed",
  "deliverable_url": "https://...mp4 | null",
  "avatar": "<look id>", "voice": "<id>", "locale": "en-AU",
  "avatar_type": "digital_twin | photo_avatar | studio_avatar",
  "engine": "avatar_v | avatar_iv | avatar_iii",
  "engine_requested": "avatar_v",
  "engine_downgraded": false,
  "resolution": "1080p",
  "brand_ok": true,
  "notes": 

engine_downgraded: true whenever the look was not eligible for the engine asked for. Never return a bare success when the render fell back — the caller needs to know it is looking at the standard path, not the recorded-twin path.

Guardrails

• Anthropic-first / cost: the MCP is HeyGen's own render service — a real spend surface. Batch locales; don't re-render on trivial script edits.
• Reference render before batch: render one, look at it, get founder sign-off on avatar + engine + motion prompt, then batch. A 40-course run at the wrong engine is both a wasted spend and a re-record conversation.
• Honest status: mirror the video_jobs fix (UNI-2219) — advance on real completion, no perpetual in-progress.
• brand-guardian is the gate: every client-facing avatar render passes it.

Integration

• video-director dispatches this for presenter segments (adds it to the production-brief team).
• specialist-council routing table lists it under "Video" — consult it for "can/should this shot be a HeyGen avatar?" before committing to a shooting plan.
• brand-video / faceless-video call it when the chosen look is a presenter.

Anti-duplication

Owns HeyGen/HyperFrames ONLY. Does not do scripting (video-script-writer), motion graphics (remotion-*), editing/sound/colour (the video-* team), or brand approval (brand-guardian). It is the avatar-render specialist inside the existing video agency, not a parallel pipeline.
