What are bilingual subtitles, and why use them?
Bilingual subtitles display the original text and its translation at the same time, usually stacked. For most people a single translated line is enough; for a few common situations the second line is what makes the video usable.
What bilingual subtitles are
Instead of replacing the original text, bilingual subtitles keep both: the source line and the translated line together. You read the translation and can glance at the original when it matters.
Why two lines beat one (for some uses)
- You can check a translation that looks wrong without pausing.
- Names, brands and technical terms that translators leave unchanged stay visible.
- You keep the original phrasing for quotes or study.
Language learning with context
If you are learning the video's language, bilingual subtitles give you the meaning and the original side by side. That turns content you cannot fully follow into reading practice with immediate context.
Checking a translation without pausing
Machine translation is good but not perfect. With both lines shown, an odd translation is easy to spot — you see the original right below it and can judge whether the meaning carried over.
What it does and doesn't do
- Original + translation shown together
- Works for web video and local files
- You can switch between original, translation, or bilingual
- Failed runs do not consume credits
- Bilingual display takes more screen space
- No live streams
FAQ
Can I turn bilingual subtitles off?

Are bilingual subtitles good for language learning?
They help because you see the meaning and the original phrasing together, so you can follow the story while picking up the language.
