Keep the original timing
Imported subtitle cues stay the timing reference, so you do not need to rebuild every timestamp.
Review before export
Open the project in Subvideo Studio and refine Japanese wording, line breaks, punctuation or terminology before downloading.
One track, several outputs
Use the Japanese version as SRT, VTT, ASS or SBV depending on where you publish it.

Translate subtitles to Japanese – FAQ
Do I have to select Japanese as the target?
No. Japanese is already fixed as the target language on this page; you only choose the source language.
Will the subtitle timing be rebuilt?
The imported subtitle cues remain the timing basis. The translation workflow focuses on the subtitle text.
What about ASS styles or VTT metadata?
Complex styling, positioning, karaoke effects, regions or player-specific metadata should be reviewed after translation. Keep the original file as a reference when those details matter.
Can I edit the Japanese translation?
Yes. After import, you can review and adjust the Japanese subtitle text in Subvideo before export.
