Video subtitle translator
Automatic translated subtitles, burned into your video, in 18 languages.
Upload a video and VidDub transcribes the speech, translates it, and burns synced subtitles into the picture, in one language or bilingual. No manual timing, and no separate subtitle file to attach.
How to translate video subtitles
- Sign in with Google or Apple and upload your video: MP4, MOV, MKV, AVI, FLV or WebM, up to 2 GB.
- Choose the language spoken in the video and the subtitle language you want.
- Pick translated subtitles only, or bilingual subtitles with both languages.
- Adjust the subtitle style on a preview frame from your video.
- Confirm, wait for processing, and download the subtitled video.
Bilingual or single-language subtitles
Bilingual subtitles show the original line and its translation together, which helps language learners and mixed audiences. Single-language subtitles show only the translation, for a cleaner picture. Either way, the subtitles are timed to the speech automatically.
Style your subtitles
Before processing, set the position (top, middle or bottom), vertical offset, text color, size and background strength, with a live preview on a frame from your video. Line-by-line script editing is not offered; style is what you adjust.
Burned-in video and subtitle file
The main result is a video with the subtitles burned into the picture, so they show on any player or social platform with no separate file. If you want to edit or reuse the lines in another program, you can also download the subtitle file.
Languages
Translate from 17 source languages: English, Chinese, Japanese, Korean, Spanish, Brazilian Portuguese, French, German, Italian, Russian, Thai, Vietnamese, Indonesian, Arabic and Hindi. Subtitles can be in any of these, plus Traditional Chinese, for 18 target languages. Full list: Supported languages.
Who uses it
- Creators adding subtitles in other languages to YouTube, TikTok and Reels videos.
- Teachers and students who want bilingual subtitles for lessons and lectures.
- Companies subtitling product demos, training videos and webinars for international teams.
- Anyone with a recorded interview, meeting or talk in a language their audience does not speak.
Free preview and plans
After you sign in, eligible short videos get a free preview of the translated, burned-in subtitles. Full download and subtitle file export are available when you choose a plan. Details: Credits.
What VidDub does not do
- Translate an SRT or VTT file on its own: VidDub works from the speech in the video.
- Edit the script line by line like a full subtitle editor.
- Download videos from YouTube or TikTok pages. URL import only accepts a direct link to a video file you have the right to use.

No. VidDub runs in the browser on a computer or phone, and there are also apps for iOS and Android.
How long are my files kept?
Finished files are removed from the server after about 24 hours. Download what you want to keep.
