Turn Chinese video or audio into Korean subtitles, exported as SRT, VTT or plain text with the original timings intact. Chinese is written without spaces, so word boundaries are decided during recognition and carry into the translation.
Where Chinese words begin and end
Chinese is written without spaces between words, so deciding where one word stops is part of recognition rather than something applied to the transcript afterwards. That matters more here than it would for a same-language transcript: the translation into Korean runs on those segments, and a boundary in the wrong place changes what gets translated.
It is also why subtitle timings on Chinese audio are worth spot-checking at the start and end of each line, where segmentation decisions land.
How Chinese audio becomes Korean subtitles
Audio in Chinese (中文) is transcribed first, then translated into Korean (한국어). Because the translation runs on the transcript rather than on the audio, the Korean subtitle file keeps the timings of the original Chinese speech — each line appears at the moment it was actually said.
From Chinese characters to Hangul
Chinese is written in Chinese characters and Korean in Hangul, 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 Korean 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.
Register in Korean subtitles
Korean marks politeness grammatically, so a translator has to choose a level of formality that the Chinese original may not have stated. The same sentence can be rendered casually or deferentially and both are accurate translations of the words.
Check the register before publishing anything with a clear audience — an interview, a lecture, a customer-facing video. It reads as a mistake to a native speaker far more readily than an awkward word choice does.
Line length in Korean
Korean builds meaning by stacking endings onto a stem, which produces fewer words but much longer ones. A Chinese line often arrives as a shorter, denser Korean line that still overruns two rows.
Shorter blocks are the fix. Splitting a long line across two subtitle events costs nothing — the timings come from the original speech either way and stay in sync.
Why translate Chinese video into Korean
Chinese is spoken principally in mainland China, Taiwan, Singapore and Chinese-speaking communities worldwide; Korean in South Korea and North Korea. A Korean 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 Chinese audio
Like Japanese, Chinese is written without spaces, so word boundaries are inferred during recognition. Mandarin is what is transcribed; Cantonese is a separate option and choosing the wrong one produces fluent-looking output that does not match the audio.
About the Korean subtitles
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.
What a Chinese to Korean subtitle file looks like
Four lines of Chinese speech, transcribed and translated, as they come out of the exported SRT. The timings are the Chinese speaker's — translation does not move them, which is why the file drops onto the original video unchanged.

What to check before publishing
Names and places, which translation handles less reliably than ordinary prose.
Idiom — a phrase that is natural in Chinese may need loosening to read well in Korean.
Line width, since Korean packs the same sentence into longer words than Chinese does.
That Hangul renders in your player, not just in the editor you exported from.
The level of formality, which Korean states grammatically whether or not the Chinese original did.
Timing on fast exchanges, where two speakers overlap.
Transcribe
Transcribe Your Video/Audio to Subtitles Automatically.
Almost always, but it depends on the font rather than the file — SRT and VTT are plain text and carry Hangul without difficulty. If you see empty boxes, the player is missing a font for the script, not reading the subtitles wrongly.
Can I control how formal the Korean is?
Not as a setting, but the subtitles are editable before you export them, which is where register gets adjusted in practice. It is worth a pass on anything with a defined audience, since Korean marks formality grammatically and the choice is visible in every line.
How do I add Korean subtitles to a Chinese video?
Upload the video, set the spoken language to Chinese and the subtitle language to Korean, then export the result as SRT and upload it alongside your video. Nothing is burned into the picture, so the subtitles stay switchable.
Does the Korean subtitle file stay in sync?
Yes. Translation happens on the transcript, so every Korean line inherits the timing of the Chinese words it came from. The file will sync with the same video without adjustment.
