Translate a video into another language in the same voice, and make the lips match: the 3 tools an AI agent such as Claude Code, Codex or Grok should reach for in 2026, compared by how the agent calls them, where they run and what they cost. Reviewed 2026-10-27.

**Our pick: HeyGen Video Translate.** One call for the translation, the speaker's voice clone and lip sync, with idempotency keys.

**How to choose:** Use HeyGen for translation, voice and lip sync in one call. Use ElevenLabs for the best dubbed voice, then sync the lips with Sync Labs. Use Sync alone to fix the lips on new audio.

| # | Tool | How an agent uses it | Runs | Price | Best for | Watch out |
|---|---|---|---|---|---|---|
| 1 | **[HeyGen Video Translate](https://developers.heygen.com/reference/create-video-translation)** (pick) | API, MCP ([agent](https://developers.heygen.com/mcp/overview)) | cloud | API credits; the MCP needs a paid plan | One call for the translation, the speaker's voice clone and lip sync, with idempotency keys. | Editing the translated text before the lip sync is not reliably supported. |
| 2 | [ElevenLabs Dubbing](https://elevenlabs.io/dubbing-api) | API, skill, MCP | cloud | Per target language | The best dubbed voice in 90+ languages. Edits regenerate only the parts that changed. | No lip sync: pair it with Sync. |
| 3 | [Sync Labs](https://sync.so/docs/api-reference/api-overview) | API, SDK | cloud | Per second | Lip sync on real footage: sync-3 (4K, occlusions) and lipsync-2-pro. Also on varg. | Free and hobby plans run one job at a time. |

**On varg** (one key, priced in credits, with an estimate before anything runs): Sync Labs — [`sync_v3`](https://varg.ai/models/sync_v3.md), [`sync_v2_pro`](https://varg.ai/models/sync_v2_pro.md).
