Translate an English video into Korean subtitles
English content in a Korean market needs Korean subtitles, and machine captions from the platform rarely produce them cleanly. This does it from the audio, not from YouTube's caption track.
You get an SRT you can edit, or a copy of the video with the line already burned in.

What happens to your video
- Upload the file or paste a public link. Phone footage (HEVC/MOV) is read as it comes off the phone.
- The audio is transcribed first, with word-level timing, so every cue starts where speech starts.
- Each line is translated on its own. Timecodes are copied through and never rewritten.
- Download the SRT, or a copy of the video with the subtitles burned in at the original resolution.
Notes on the audio
- Korean also puts the verb last, and the verb ending sets the tone (formal, casual, written). The translation has to pick one register for the whole video.
- Particles are short and attach to the previous syllable, so speech recognition often glues them to the wrong word and shifts a boundary.
- Korean subtitle lines tend to break around 14-16 characters. The English translation of the same line usually fits in 38-42 characters.

Questions
Will the Korean lines be too long for the screen?
Lines are kept short, but Korean usually runs longer than the English source, so a manual pass on line breaks is worth doing. Korean subtitle lines tend to break around 14-16 characters. The English translation of the same line usually fits in 38-42 characters.
Does it use YouTube's auto-captions?
No. It transcribes the audio itself, so it also works for files with no captions at all.
Can I get both languages?
Yes, bilingual output keeps the English line above the Korean one.
