## Consent

Driving a real person's mouth from a separate audio track is dual-use. Refuse user requests that target real public figures without consent, or that aim at defamatory or sexually explicit synthetic media. The skill itself does not gate inputs — the responsibility rests with the operator.

## Pick the right model

Listed newest first within each subtype. The agent picks one route based on: input shape (portrait still + audio vs source video + audio vs script-only), quality tier, and budget.

### Source video + audio → lip-synced video (mouth-swap on existing footage)

**Sync Labs sync v2 Pro** — `sync/sync/lipsync/v2/pro` *(default for premium)*
> Sync Labs' premium lip-sync — state-of-the-art mouth motion onto an existing video. Preserves the rest of the frame untouched.
> Pick for: hero-quality dubs, lipsync on professionally-shot video, foreign-language dubbing where mouth fidelity matters most.
> Avoid for: cost-sensitive batch jobs — drop to **sync v2**.

**Sync Labs sync v2** — [`sync/sync/lipsync/v2`](https://www.runcomfy.com/models/sync/sync/lipsync/v2?utm_source=skills.sh&utm_medium=skill&utm_campaign=lipsync)
> Standard Sync Labs tier, same workflow as Pro.
> Pick for: scaled / batch lipsync jobs, drafts.
> Avoid for: hero delivery — use **v2 Pro**.

**Kling Lipsync (audio-to-video)** — [`kling/lipsync/audio-to-video`](https://www.runcomfy.com/models/kling/lipsync/audio-to-video?utm_source=skills.sh&utm_medium=skill&utm_campaign=lipsync)
> Kling's lip-sync onto a source video, driven by an audio track.
> Pick for: Kling-pipeline integration; alternative to Sync Labs.
> Avoid for: top-tier mouth fidelity — Sync Labs Pro is the industry benchmark.

**Creatify Lipsync** — [`creatify/lipsync`](https://www.runcomfy.com/models/creatify/lipsync?utm_source=skills.sh&utm_medium=skill&utm_campaign=lipsync)
> Creatify's lipsync endpoint.
> Pick for: Creatify-ecosystem workflows.
> Avoid for: comparison shop
