Generate English subtitles for your Korean videos

From Hangul to the Latin alphabet

Korean is written in Hangul and English in the Latin alphabet, so the exported file uses a different writing system from the audio that produced it. The subtitle formats handle that — SRT and VTT are plain text and carry any script — but the font in whatever plays the file has to cover it.

This is the most common reason a English subtitle track looks correct in an editor and shows boxes or blanks on a device. Test on the target platform before you publish a batch.

How Korean audio becomes English subtitles

Audio in Korean (한국어) is transcribed first, then translated into English (English). Because the translation runs on the transcript rather than on the audio, the English subtitle file keeps the timings of the original Korean speech — each line appears at the moment it was actually said.

Why translate Korean video into English

Korean is spoken principally in South Korea and North Korea; English in worldwide. A English subtitle track is what lets one recording reach both audiences without re-recording, re-editing or dubbing it.

Because subtitles are a separate file rather than part of the picture, you can attach several language tracks to the same video and let viewers pick.

About the Korean audio

Korean marks formality grammatically, and the register a speaker uses carries real information — transcription preserves it rather than flattening everything into one politeness level. Hangul is featural and compact, so Korean subtitle lines tend to fit comfortably in two rows.

About the English subtitles

English has a wider spread of accents than any other language here, and the gap between spelling and pronunciation means recognition leans on context rather than sound alone. Names and technical terms are where errors concentrate, because those are exactly the words context cannot predict.

What a Korean to English subtitle file looks like

Four lines of Korean speech, transcribed and translated, as they come out of the exported SRT. The timings are the Korean speaker's — translation does not move them, which is why the file drops onto the original video unchanged.

1
00:00:01,000 --> 00:00:03,240
Good morning, everyone.

2
00:00:03,600 --> 00:00:06,120
Thank you all for coming.

3
00:00:06,480 --> 00:00:09,300
Let's start with the first question.

4
00:00:09,700 --> 00:00:12,040
See you next time.

What to check before publishing

• Names and places, which translation handles less reliably than ordinary prose.
• Idiom — a phrase that is natural in Korean may need loosening to read well in English.
• That the Latin alphabet renders in your player, not just in the editor you exported from.
• Timing on fast exchanges, where two speakers overlap.
