How to translate a video with VidDub
The same steps as the iOS and Android apps, in the browser.
Sign in, upload or import a video you have the right to use, choose languages and subtitle style, confirm, wait, then download. Dubbing is optional after translation.
1. Sign in
Open viddubapp.com and sign in with Google or Sign in with Apple. Google on the website uses the same account as the Android app. Sign in with Apple uses the same Apple ID as the iOS app. Upload requires an account.
2. Upload or import
Choose a local MP4, MOV, MKV, AVI, FLV, or WebM file up to 2 GB, or paste a direct http(s) link to a video file you have the right to use.
URL import is not a downloader for arbitrary YouTube or TikTok pages.
3. Source and target languages
Workspace opens automatically. Set the spoken source language and the target language. Traditional Chinese can be a target, not a source.
4. Subtitles
Choose one language or bilingual subtitles. On the preview frame, set position, vertical offset, color, and size. Subtitles are burned into the video. You cannot rewrite lines one by one. More: Subtitle translator.
5. Confirm and process
Confirm the settings. If this account still has its free preview and the video is 10 minutes or shorter, playback is about the first third and does not spend credits. A longer video needs credits before translation. Languages: Supported languages. Plans: Credits.
6. Download
When the job finishes, download the video, copy a short-lived link, or use the subtitle download control. Files are deleted after about 24 hours.
The free preview plays about the first third. Full download, copying a link, and subtitle export need credits. A 90-second paid export uses 2 minutes, because leftover seconds round up. Dubbing is optional and is not in the preview.
7. Optional dubbing
After the translation finishes, you can pick a voice and generate a track timed to the original speech. Skip this if burned-in subtitles are enough. It is not available on the free preview. See AI dubbing.
