Upload a video, pick a target language, and get back the same video dubbed into that language with the speaker's lips re-synchronized to match the new audio. Great for turning English YouTube content into Spanish, French, Chinese, etc.
Four steps run server-side in sequence: (1) Whisper transcribes the original audio, (2) MadLAD translates the transcript to your target language, (3) Kokoro generates natural speech in that language, (4) Sync Lipsync v2 remaps the speaker's mouth to match the new voice. All done in one request — no juggling tools yourself.
The dropdown covers 20 top-demand languages (Spanish, French, German, Portuguese, Italian, Chinese, Japanese, Korean, Arabic, Hindi, Turkish, Russian, Dutch, Polish, Vietnamese, Indonesian, Thai, Hebrew, Swedish, English). MadLAD technically supports 450+ — ping us if you need others.
Dubbing uses paid tokens only (~100,000 per clip). Sync Lipsync v2 is the expensive step — the first three are free self-hosted. Sign-up bonus credits do not unlock this tool.
Clips under 30 seconds dub in about 1–3 minutes. Longer videos take proportionally longer. Hard cap 100 MB upload. For feature-length work, split into scenes and dub each.
No — Kokoro uses one of 174 built-in voices (37 languages), not a cloned version of the original speaker. For identity-preserving voice cloning you'd need our separate /voice/clone/ tool plus a custom pipeline.
Sync Lipsync v2 is state-of-the-art for single-speaker forward-facing shots. Multi-speaker scenes or profile-view clips can drift. Best results come from close-up talking-head footage.
The simple picker offers Auto / Male / Female. For fine-grained voice selection, use /voice/tts/ first to preview and copy the voice ID, then we can wire that through. Coming soon in the UI.
No. The uploaded video is deleted within minutes of processing. The output is kept on our CDN for 24h (7d for paid users) at the share link.
Yes — for that pure lip-sync workflow (your video + your pre-recorded audio), use the underlying /v1/image/edit/ or a custom endpoint. Dubbing combines all four steps automatically.
Use /transcribe/ for subtitle files (SRT/VTT), or /translate/subtitle/ to translate an existing SRT. Dubbing replaces the audio; subtitles overlay text — different outputs.
Yes — POST multipart video to /v1/video/dubbing/ with target_lang. Returns {output_url, transcript, translated_text}. See /api/ for docs.
