voice-to-lip-sync is a skill for Claude Code from danielrosehill/Claude-AI-Video-Producer-Plugin. It costs 43 tokens per session (545 once invoked), scanned A, original, MIT.

A workflow that creates spoken audio and synchronizes it with an existing silent video of a character speaking. It is intended for talking-head or dialogue footage.

In plain words
What is it for?
Use it to create voice lines, apply a voice clone when provided, adjust delivery, and produce a lip-synced character clip.
Why use it?
It adds matching speech to a visual clip when the video already exists but has no audio.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

voice-to-lip-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Voice → Lip-Sync Pipeline

Generates a voice line and conforms an existing silent character clip to it.

When to use

  • Talking-head or dialogue shots where you have a generated character clip but no audio.
  • Voice-cloning a specific speaker for narration with on-screen presence.

Inputs

  • The line to be spoken (from scripts/final/script.md or the shot brief).
  • A character clip in clips/raw/ or generation/image-to-video/.
  • Voice selection from brief/tools-and-models.md. If a voice clone is in use, source audio lives at assets/voice-clones/<name>.wav.

Steps

  1. Confirm the line. Read it back to the user with character + tone.
  2. Generate voice take. Call the configured voice model (ElevenLabs, etc.). For voice clones, pass the clone source from assets/voice-clones/. Save to generation/voice/NN-shortname-vN.wav. Save script + model + voice ID to generation/prompts/NN-shortname-vN-voice.md. Log it.
  3. Iterate. Play it back (or describe what was generated). Offer to retry with adjusted prosody/emotion settings.
  4. Lip-sync. Pass the approved voice + character clip into the configured lip-sync model. Save to generation/lip-sync/NN-shortname-vN.mp4. Log it.
  5. Verify sync quality. Surface the result. Lip-sync models often need iteration on which face region to lock to or whether the source clip's mouth is occluded.
  6. Accept. Copy to clips/raw/ and suggest /promote-take.

Common gotchas

  • Source clip face visibility. Lip-sync needs a clear, mostly-frontal mouth. If the character clip cuts away or shows them in profile, the sync will be poor — prefer regenerating the visual with a more frontal angle.
  • Voice take duration vs clip duration. Voice takes usually need to be slightly shorter than the clip to leave room for natural pauses. If the line is too long, either shorten the script or regenerate the visual longer.
  • Audio sample rate. Lip-sync models often expect 16kHz or 24kHz mono. Convert with ffmpeg if the voice model outputs 44.1kHz stereo.
