Length and layout
Korean is fewer characters than the English original. Both languages are written left to right, so the layout does not change — only the wording and line length do.

Translate English video into Korean subtitles
Upload a video in English. SubFlow transcribes the speech, translates every caption into Korean, and keeps both languages on the same timeline so you can review them side by side — then export subtitles, a subtitled video, or a Korean dub.

Getting Korean right
Korean has several speech levels; the translation uses a polite, neutral level that suits most videos, and the editor lets you shift it for a casual audience.
Workflow
From English to Korean in three steps.
Upload the English video
Add a video or audio file. SubFlow transcribes the English speech into timed captions.
Translate into Korean
Pick Korean as the target. Every caption is translated with the surrounding lines as context, then shown beside the original.
Review and export
Fix names and terms, split any caption that runs long, then export Korean or bilingual subtitles, a subtitled video, or a Korean dub.
Common questions
English to Korean, answered.
Can SubFlow recognise English speech automatically?
Yes. Leave the source on automatic detection or pick English yourself. Accents, fast speech and overlapping speakers are handled well by the Whisper model; background music is the most common cause of a dropped line.
Will the Korean subtitles fit on screen?
Korean reads comfortably at about 12 characters per second with about 16 characters per line. Korean is fewer characters than the English original. Review the longest captions and split any that crowd two lines.
Can I dub a English video into Korean?
Yes, on the Pro plan. The Korean dub uses a ko-KR voice and is spoken from the translated subtitles, so correcting a line in the editor changes what the voice says.
Can I export English and Korean together?
Yes. Export the Korean subtitles alone, the original English, or a bilingual SRT with both on each caption — or burn either into the video.
