Bilingual subtitles online
Updated 2026-11-12
Bilingual subtitles put two languages in the picture at once. People also call them dual language subtitles or double subtitles. VidDub burns both lines into the video you upload.
What bilingual subtitles are
One line is the language spoken in the video. The other line is the translation. Both sit in the frame, so the file still makes sense when someone plays it with the sound off or in a room that uses two languages. When you upload, use a video you have the right to use.
Who uses dual language subtitles
- Language learners who want the original line and the translation on the same video.
- Teachers publishing a course for a class that reads two languages.
- Cross-border teams catching a meeting in a second language.
- Creators posting a short video for viewers abroad.
Style you can set
On the preview you set position, size, color, background opacity, and vertical offset. The double subtitles stay where you put them, in the picture you upload. VidDub covers 17 source languages and 18 target languages.
How it works
- Sign in and upload a video.
- Choose the spoken language and the translation language, then pick bilingual lines.
- Set the style on the preview and play the result. The full download is the paid step, from $3.90.
