To translate a Chinese video to English — with an actual English voice track, not just subtitles — you need three things: accurate Chinese speech recognition, a translation you can review before it's spoken, and natural English voices matched to each speaker. aitrans.video is a Chinese⇄English dubbing workbench built around exactly that: upload a video up to 3 hours long, review the transcript and translation sentence by sentence, pick voices per speaker, and export a dubbed MP4 plus subtitles, clean audio, and an editable draft project.
You can hear the pipeline right now: try 3 minutes free — no signup. The anonymous preview currently demos the English→Chinese direction; Chinese→English is covered by free trial credit the moment you create an account — still no credit card.
Most global dubbing platforms treat Chinese as one of 90–175 supported languages. That breadth is genuinely impressive — but it means Chinese gets the same generic pipeline as everything else, and Chinese is not a generic language for speech recognition:
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 our pipeline treats the transcript as a first-class, reviewable artifact instead of a hidden intermediate step.
Most tools are one button: upload, wait, download, hope. aitrans.video is a staged workflow where you can intervene at every point that matters — or skip straight through if the output is already right.
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.
A 40-minute product deep-dive, a 90-minute lecture, a 3-hour livestream recap — long-form is where Chinese creators have the most valuable content and where most tools hit a wall. Many popular platforms cap uploads at 30–60 minutes per video or meter dubbing by the minute, which makes long videos either impossible or painfully expensive.
aitrans.video accepts up to 3 hours in one task, and pricing is built so long videos aren't punished by the minute. If long-form is your main use case, see the full cost breakdown in our long video translation guide — it compares what a 3-hour dub actually costs across the major tools (verified 2026-07-03).
Most dubbing tools deliver a finished video file and nothing else. If you spot a problem afterwards, you start over. aitrans.video exports a complete working set:
| Deliverable | What it's for |
|---|---|
| Dubbed MP4 | Publish-ready English version of your video |
| Bilingual SRT subtitles | Chinese + English captions for accessibility and SEO on YouTube |
| Clean dubbed audio | The English voice track alone — remix it however you like |
| Jianying draft project | An editable draft for Jianying (剪映, CapCut's Chinese edition) — keep cutting, add graphics, adjust timing in the editor you already use |
That last one matters if your workflow lives in Jianying: instead of a locked file, you get a project you can keep working on.
Honesty saves everyone time:
Two tracks: subscription plans for regular volume, and pay-as-you-go credits with no monthly commitment — so a one-off 2-hour project doesn't require signing up for a monthly meter. Payment works the way Chinese creators actually pay: WeChat Pay, Alipay, international cards (via Paddle), and PayPal. Current numbers are on the pricing page.
Yes. aitrans.video transcribes the Chinese audio, translates it, and generates an English voice track with AI voices matched per speaker — a full dub, not just translated subtitles. Signing up gives you free trial credit to run a Chinese→English task on your own video.
No ASR is perfect on real-world Chinese audio — fast speech, homophones, and mixed Chinese-English are genuinely hard. That's why the workflow shows you the full transcript for review before translation. You correct a misheard line once, at the source, instead of discovering it in the finished dub.
Yes — sentence by sentence. Translation review is a standard step in the pipeline, not a premium add-on. You can also regenerate the audio for any single sentence after the dub is produced.
Up to 3 hours per task. Most mainstream tools cap single videos at 30–60 minutes or meter dubbing per minute; see our long-video cost comparison for the details.
Yes. Speakers are detected during transcription, and you choose (or auto-match) a distinct voice for each speaker.
Voice cloning is available, so the English track can carry a voice similar to the original speaker's. Alternatively, automatic voice matching suggests a suitable voice from ~1,000 options across three TTS engines.
A dubbed MP4, bilingual SRT subtitles (Chinese + English), the clean English audio track, and a Jianying (CapCut China) draft project you can keep editing.
There's a free anonymous preview that runs the real pipeline on 3 minutes of video — no signup, no credit card — currently in the English→Chinese direction. For Chinese→English, creating a free account gives you trial credit to run your own task; the trial doesn't require a card and never auto-charges.
