AITrans.Video turns a Chinese video with audible speech into an English dub with English captions. Upload a video you own or are licensed to localize — a course, tutorial, interview or livestream clip. Chinese is the source language, English is the target language, and the English version is the deliverable.
Start with one short clip. Watch a real Chinese-to-English sample, then try a watermarked preview on your own clip. Chinese → English appears in the live trial selector when it is available; the directions, upload limits and preview length shown there are the ones that apply to you. Create an account to save a preview or start an eligible full task.

The sample above turns 34.01 seconds of Mandarin into a 29.76-second English dub with English captions. It uses a preset English narrator and retimed video. It does not demonstrate voice cloning or lip-sync, and the picture was retimed to the English audio with caption space added.
The source is a China News Service clothing interview published on 30 April 2019, excerpted from 00:58.08 to 01:32.08 under CC BY 3.0. After source review, the generated dub received an automated listening check. See the original video and the Wikimedia Commons record for attribution, and the full case notes for the source record.
English transcript: Here in Subei, our traditional clothing has been passed down for three or four hundred years. We build on that tradition with new designs, making the garments a little shorter or more fitted, with medium-length and short styles in all sorts of variations. Young people today often wear these styles when they go to work. But when it comes to weddings and festivals, young people still love our most traditional styles.
Chinese speech can be difficult to transcribe accurately because the language has dense homophones, tones, fast conversational delivery, code-switching, and named entities. The transcript is the foundation of a useful dub:
The uncomfortable truth about any AI dubbing tool: the transcript is the foundation. If the Chinese transcript is wrong, the English translation is confidently wrong, and the dub is fluently wrong. That's why the workflow treats the transcript as a reviewable artifact rather than a hidden intermediate step.
In Studio, review the source transcript and translation and choose available voices before generation. Express processes automatically; review its completed result before publishing.
Studio vs Express. Studio is the reviewed path: you check the transcript and translation and choose voices before the dub is generated. Express runs automatically from upload to result. Available downloads depend on the mode and access your task actually has — Studio includes draft export, while Express may offer draft export as an unlock.
Editing after completion is separate. A post-completion Edit stage may be offered for your task, and using it can involve task, plan, or access charges depending on your plan. Check whether the Edit control is enabled on your task before planning around it — it is not a promise that every line can be changed after the fact at no cost.
Three different language settings. The source language is what the speakers say in your file (Chinese). The target language is what the dub will be spoken in (English). The interface language is the language the app itself is displayed in — change it whenever you like; it does not affect the dub. Available source/target combinations are the options shown on the creation page.
For bilingual teams, this workflow is the whole point: a Chinese-speaking editor can verify the source transcript while an English-speaking editor polishes the translation, in the same project.
After a short excerpt works for you, move on to a course module or full interview. The supported duration depends on your plan, and the current per-task limit is shown in your account and on the creation page — check it before uploading a long source.
Check the long video translation guide and current pricing before uploading a long source. If a video is over the current limit, prepare independent chapters or excerpts in your own editor and submit each one as its own task.
Available downloads depend on the task's mode and export access. Standard media files work without installing any editor:
| Deliverable | What it's for |
|---|---|
| Dubbed MP4 | An English-audio version of your video |
| Bilingual SRT subtitles | Chinese + English captions for accessibility and publishing |
| Clean dubbed audio | The English voice track on its own, for your own mix |
| Jianying draft project | A Studio deliverable for Jianying (剪映, CapCut China); Express may offer an unlock |
| CapCut draft project | A separate, editor-specific package with the same media, subtitles, and timeline; tested with Windows CapCut 9.4.0.4015 |
Drafts are editor-specific packages: a Jianying draft opens in Jianying (剪映, CapCut China), and the CapCut draft is a different package that we tested with Windows CapCut 9.4.0.4015 — playback, subtitles, save/reopen, and export all worked in our desktop test. CapCut Mac, web, mobile, and other versions have not been verified; the MP4, SRT, and audio downloads remain equally clear choices for any workflow, including international CapCut Desktop.
Product demos, tutorials, and livestream clips recorded in Chinese can be turned into English video assets while keeping the source transcript and translation available for review.
For this workflow, AITrans.Video gives sellers three practical controls:
Honesty saves everyone time:
Check current pricing for plan details and payment options. The trial page shows available directions, upload limits, and preview lengths.
Current base-plan source-length limits: 10 minutes for Free, 45 minutes for Plus, and 3 hours for Pro. These apply to one source video, not processing credits or preview length.
Monthly USD plan pricing: Plus — $16.99; Pro — $49.99. A monthly plan purchase covers one month with no automatic renewal. These are plan prices, not a quote for one video. Processing depends on your task settings and available credits.
Before confirming, check the duration limit and task estimate on the creation page. Your balance determines whether you have enough credits to submit; the charge follows the task's applicable billing rules.
You upload a video you own or are licensed to localize, with audible Chinese speech. The task transcribes the Chinese, translates it, and produces an English voice track with English captions. Available downloads depend on your task's mode and export access.
The source language is the language spoken in your file (Chinese). The target language is what the dub is spoken in (English). The interface language is only the language the app is displayed in; changing it does not change the dub. Available source/target combinations are the options shown on the creation page.
Yes, sentence by sentence in the Studio workflow. Post-completion Edit is a separate stage that may or may not be enabled for your task, and using it can involve task, plan, or access charges — check whether the Edit control is available on your task before relying on it.
Current base-plan source-length limits: 10 minutes for Free, 45 minutes for Plus, and 3 hours for Pro. These apply to one source video, not processing credits or preview length. See current pricing, then review the limit and estimate on the creation page before uploading.
Monthly USD plan pricing: Plus — $16.99; Pro — $49.99. A monthly plan purchase covers one month with no automatic renewal. These are plan prices, not a quote for one video. Processing depends on your task settings and available credits. Check the task estimate and current pricing before confirming.
Speakers are detected during transcription. Studio lets you choose an available English voice for each speaker; Express selects voices automatically. Voice cloning may be offered for authorized material when the task qualifies—check the available controls on your task.
It depends on the task's mode and export access. Downloads may include a dubbed MP4, bilingual SRT subtitles, clean English audio, and an editor draft project — choose Jianying (CapCut China) or CapCut when generating. Check the downloads listed on your task.
No. Use the MP4, subtitles, and clean audio on your task's download screen. When draft export is available, Jianying (剪映, CapCut China) and CapCut are two separate editor-specific packages built from the same content. The CapCut draft was tested with Windows CapCut 9.4.0.4015; CapCut Mac, web, mobile, and other versions have not been verified.
The anonymous preview can accept Chinese → English when that direction appears in the live selector. Upload limits and preview length come from the live trial service. An account is used to save a preview or start an eligible full task — see the trial details.
Yes. Product demos, tutorials, and livestream clips are suitable use cases. Available downloads depend on the task's mode and export access; draft output targets Jianying (CapCut China) or CapCut (Windows 9.4.0.4015 verified).
Longer sources are supported up to the current per-task limit. If a video is longer than that, cut it into independent chapters or excerpts in your own editor and submit each one as its own task, reviewing each result separately. There is no built-in splitter, no automatic recombination, and no guarantee of speaker consistency across separate tasks. See the long video translation guide.
