About Korean subtitling

Korean subtitles for an audience with high expectations

Korean is written in Hangul, an alphabet whose letters combine into syllable blocks, so a word occupies fewer character positions than its English equivalent. Korean text contracts against English, though as with other East Asian languages the saved space does not convert directly into saved reading time.

Korean audiences are also unusually exposed to subtitling standards, given how much Korean content is subtitled outward for international distribution and how much foreign content arrives subtitled. The reference point for quality is high.

At GoLocalise, we work with native Korean subtitlers and every file passes linguistic and technical QA before delivery.

Which do you need?

Open captions, closed captions or SDH

Three different deliverables that people often ask for by the wrong name. Here is the short version.

Open captions

Burnt in

Korean subtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for a social feed that autoplays muted.

  • Always visible
  • Hangul set in your brand typeface, at the size and position you choose
  • Delivered as a finished video file

Closed captions

Switchable

A separate file the viewer can turn on and off, and that can carry several languages at once. The standard for YouTube, Vimeo and the streaming platforms.

  • Viewer controls them
  • Multiple languages from one video
  • Indexed by search engines

SDH

Accessibility

Subtitling for the deaf and hard of hearing: dialogue plus speaker IDs and the sound effects and music cues that carry meaning.

  • Speaker identification
  • Non-dialogue audio described
  • Meets accessibility requirements

Subtitles or captions? The two terms are often used interchangeably. Strictly, subtitles translate the dialogue for viewers who can hear the audio, while captions are same-language and add speaker labels and sound cues for viewers who cannot. We produce either — translated Korean subtitles or same-language Korean captions and SDH — in whichever form your platform and audience require.

What we subtitle

Korean subtitling for every kind of content

Korean subtitling spans K-content, global corporate rollouts and accessibility work, and each format carries its own expectations for register and on-screen text. These are the project types we handle most.

Corporate & training video

Internal comms, onboarding and product training subtitled for global teams and LMS delivery.

eLearning & online courses

Timed, readable subtitles for course platforms, MOOCs and instructional video.

Documentary & factual

Festival, broadcast and streaming documentaries, including interview clean-up and on-screen text.

Advertising & social

Burnt-in captions for muted autoplay on Instagram, TikTok, YouTube and paid social.

Streaming & OTT

Platform-spec subtitle and caption files for VOD, OTT and broadcast delivery.

Accessibility (SDH & closed captions)

Same-language SDH and closed captions to meet WCAG and accessibility requirements.

Events, webinars & conferences

Recorded talks, town halls and webinars captioned for on-demand viewing.

E-commerce & product video

Short product and explainer videos captioned to lift conversion and reach.

How can we help you?

Your project manager has everything covered

One point of contact from brief to delivery, and both a linguistic and a technical check on every file.

1

Brief review

We review your video, your audience, and the speech level the content calls for.

2

Template and translation

Where needed, we create an English subtitle template first, then send it to a native Korean subtitler.

3

Timing and quality checks

Subtitles are timed against the video and checked for reading speed, line length in Hangul syllable blocks, eojeol spacing at the breaks, and format compliance.

4

Delivery and display check

Files delivered in the format you need, with the Hangul checked on the destination player.

Our standards

The specs we work to

Readable subtitles are a matter of measurable limits, not opinion. These are the defaults we apply to Korean unless your style guide says otherwise.

16characters

Maximum per line

Latin characters count as half

2lines

Maximum on screen

One line preferred where it fits

12chars/sec

Reading speed

Nine for children’s content

1second

Minimum duration

Seven seconds maximum

Hangul syllable blocks pack more into each character position, but reading speed standards for Korean are set in characters per second at rates below those used for Latin script. A line that looks short on the page can still exceed what a viewer can read in the time available. Shorter text does not mean more room.

Korean specifics

Speech level is not a style choice

Korean marks formality through verb endings in every sentence, so the choice of register is not cosmetic. Corporate and instructional content generally uses a consistent polite level; dialogue-driven material should track the speakers as they shift between them.

Subtitles that apply one level uniformly across a file flatten relationships the dialogue is actively establishing — who defers to whom, who is close, who is distant — which an audience that watches a great deal of subtitled content notices immediately.

Honorifics and titles need the same care. They rarely have direct English equivalents, and dropping them loses meaning Korean viewers expect: job titles, kinship terms used between non-relatives, name-plus-title forms. We handle them by the conventions of the market rather than translating literally or removing them.

Most common questions

What speech level should Korean subtitles use?

It should follow the relationships on screen. Korean marks formality through verb endings in every sentence, so the choice is not cosmetic: applying a single level across a whole file removes information about who is speaking to whom and how. Corporate and instructional content generally uses a consistent polite register, while dialogue-driven material should track the speakers.

How are honorifics and titles handled?

Carefully, because they rarely have direct English equivalents and dropping them loses meaning that Korean viewers expect to see. Job titles, kinship terms used between non-relatives, and name plus title constructions all carry social information. Our subtitlers handle them according to the conventions used in the market rather than translating them literally or removing them.

Does Korean text being shorter mean I can fit more in?

Not straightforwardly. Hangul syllable blocks pack more into each character position, but reading speed standards for Korean are set in characters per second at rates below those used for Latin script. A line that looks short on the page can still exceed what a viewer can read in the time available.

How quickly can a Korean subtitling project be delivered?

A short video is normally back with you inside 24 to 48 hours. What changes it is running time, the number of formats leaving with the job, and whether we transcribe the Korean audio before we translate. The timeline is agreed with your project manager before work begins.

How much does Korean subtitling cost?

Korean subtitling is normally quoted per minute of video, with the price shaped by running time, whether we transcribe before translating, whether you are taking SDH or burnt-in delivery, and the number of delivery formats. Every project is priced individually and covered by our Price Match Promise, so send us the video for an exact, no-obligation quote.

Do you deliver SRT files, closed captions or burned-in Korean subtitles?

All three. We supply switchable closed-caption files such as SRT and VTT for YouTube, Vimeo and streaming platforms, broadcast formats like TTML and SMI, and open captions burned into the video for muted social content. Korean line breaks follow the language's own segmentation rules, not the English ones, which keeps the reading natural.

Can you provide Korean SDH and closed captions for accessibility?

Yes. We produce Korean SDH with speaker identification and described sound effects, along with standard closed captions, so your content satisfies WCAG and platform accessibility requirements. It is a standard part of our Korean captioning service.

Can you also translate the script and record a Korean voice over or dub?

Yes. Beyond subtitles we translate on-screen text and scripts, record native Korean voice over, and produce full dubs — keeping honorifics, speech level and terminology consistent across the subtitle file and the spoken track so nothing clashes.

Do you also add same-language Korean captions, not just translated subtitles?

Yes. As well as translating into Korean, we produce same-language Korean captions and SDH — the closed captioning many teams need for accessibility, social video and search. If your video is already in Korean and you simply want accurate on-screen captions or SDH, that is a core part of our Korean captioning service.

Can you start from a Korean SRT file we already have?

Absolutely. If you already have a transcript, script or a draft SRT/VTT, we can spot, time and quality-check from it rather than starting from scratch, which usually lowers the cost. If you don't, we transcribe the Korean audio first. Either way every file goes through the same linguistic and technical QA.

Will your Korean subtitle files open in our editing software?

Every common one. We deliver Korean SRT, VTT, STL and TTML files that drop straight into Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve, Camtasia and most online editors and players. If you would rather not manage a separate file, we burn the subtitles into an MP4 or MOV instead.
