Add Korean Subtitles to Video
ViralMint is a free Korean subtitle generator — Whisper transcribes your video locally and adds accurate 한국어 Hangul captions you can burn in or export.
Free Korean subtitle generator, powered by local Whisper
ViralMint adds Korean (한국어) subtitles to any video using local Whisper transcription, outputting clean Hangul with accurate word spacing. Paste a video and get word-level Korean timestamps in seconds, then burn word-by-word captions or export .srt/.ass. To turn an English video into a Korean cut, translate-and-dub transcribes the original locally, translates to Korean, and re-times the subtitles — useful for the globally influential K-content creator scene. It all runs on your machine: no upload, no per-minute cap, no watermark.
How to add Korean subtitles to a video
-
Open the caption tool
Launch ViralMint and open Tools → Captions. It accepts mp4, mov, mkv and webm.
-
Drop in your video
Local Whisper transcribes it into Korean (한국어) with word-level timestamps — on your machine, nothing uploads. If the audio is another language, translate-and-dub can convert it to Korean first.
-
Style or export
Burn word-by-word animated Korean captions (viral / classic / bold), or export a standalone .srt / .ass file for any editor.
-
Render the mp4
ViralMint burns the Korean subtitles in with FFmpeg and writes the final mp4 — original untouched, zero watermark.
Frequently Asked Questions
Does it output proper Hangul with spacing?
Yes. Whisper transcribes into Hangul with Korean word spacing (띄어쓰기) applied, so the captions read naturally rather than as one run-on string.
Can I get Korean subtitles from an English video?
Yes — translate-and-dub transcribes the English audio locally, translates to Korean, and re-times the captions for an accurate Korean version.
Is there a watermark?
No. Captioning runs in the free ViralMint desktop app with no watermark and no monthly minute cap.
