Translate your original channel file in four steps
- Upload your original file. Sign in and upload an authorized MP4, MOV or WebM recording up to 200 MiB and 10 minutes. This tool does not download a YouTube link.
- Preview the translated voice. Choose from 13 target languages. Listen to up to 30 seconds without spending credits; the preview does not include lip sync.
- Generate and review. Check the full-dub quote before starting. Then review the transcript and translation, edit translated sentences and review each edit's quote before regenerating.
- Download and publish yourself. Export dubbed video, mixed audio, voice-only audio and separate source/translated SRT/VTT subtitles. Upload the files through your own publishing workflow.
Prepare a dub for your channel
Start from a file you own or have permission to reuse. This workflow does not connect to YouTube Studio, manage channel settings or promise that a channel has access to any YouTube feature.
Keep a copy of the original. Review AI transcription, names, channel catchphrases and pronunciation. Subtitle downloads are separate files for each language. Caption styling controls are not offered.
Keep the voice and background in context
- Authorized cloning. Solo recordings can use a clone of one identified speaker with consent and at least 10 seconds of usable sample speech. Otherwise use stock voices; voice similarity is not guaranteed.
- Background audio. Music and effects are separated and mixed with translated speech. Listen for separation artifacts.
- Sentence timing. Speech is fitted to each sentence slot and following silence. Overlapping or short lines need review.
- Presenter on camera. Optional AI lip sync supports one front-facing speaker in video longer than 1 second and up to 210 seconds. Review mouth alignment before publishing.
Languages and pricing
English, Simplified Chinese, Brazilian Portuguese, Latin American Spanish, French, German, Japanese, Korean, Vietnamese, Arabic (Modern Standard), Dutch, Polish and Hungarian are the 13 target languages.
Full dubs can include up to 5 target languages; each has its own charge. See pricing for plans and review the workspace quote before generation. Failed languages release their reservations.
Related tools and rights
Use the video translator for recorded video or TikTok translate for an authorized short clip. This is file dubbing, not live interpretation or automatic channel publishing.
You must own or obtain permission for the video, voices, music and images. Review AI output and the terms before republishing a translated recording.
