Built for real dialogue
More than replacing one audio track with another
A usable dub has to preserve who spoke, what they meant, and when the line belongs in the scene.
Context beyond isolated lines
Neighboring dialogue helps resolve omitted subjects and context-dependent Japanese expressions.
Names remain editable
Review romanization, names, titles, and specialist vocabulary before synthesis.
Separate speakers stay attributable
Speaker-aware processing retains dialogue turns instead of creating one narrator track.
Scene audio remains present
Music, ambience, and supported non-verbal events are retained in the final mix.

Japanese to English video translation FAQ
Can VDub translate Japanese with omitted subjects?
Translation uses neighboring dialogue for context, but ambiguous wording should still be reviewed before final delivery.
How are Japanese names and honorifics handled?
They remain part of the reviewable translation, so you can choose the preferred romanization or English form.
Does it work with multiple Japanese speakers?
Yes. Speaker turns are detected and translated individually, with best results from clear non-overlapping speech.
Will English speech stay synchronized?
The timing workflow aligns generated speech without silently dropping accepted translated text.
Can I download subtitles?
Subtitle artifacts are produced with the translation task when available in the completed output.
