Vietnamese subtitling services
Native Vietnamese subtitlers for corporate video, eLearning, streaming content, documentary and advertising. Delivered correctly rendered, in the exact shape your platform expects. Part of a full Vietnamese language service: subtitles, voice over scripts, and translation of any content you need.
About Vietnamese subtitling
Latin script, but not the Latin script your player expects
Vietnamese is written in chữ Quốc ngữ, a Latin-based alphabet adopted officially in the early twentieth century. The language also stacks diacritics. A single vowel can carry one mark identifying the vowel itself and a second marking the tone, combining into characters such as ể.
In subtitle rendering with tight line spacing, the upper marks tend to get clipped, and a file that is correct in the editor can lose the information that distinguishes one word from another in the player. A missing mark is not a cosmetic problem: it changes the word.
At GoLocalise, we work with native Vietnamese subtitlers and check output in the environment it is going to play in.


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 inSubtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for social feeds that autoplay muted — and it settles the diacritics at delivery instead of leaving them to the player.
- Always visible
- Diacritic rendering fixed at delivery
- Delivered as a finished video file
Closed captions
SwitchableA 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
AccessibilitySubtitling 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 Vietnamese subtitles or same-language Vietnamese captions and SDH — in whichever form your platform and audience require.
What we subtitle
Vietnamese subtitling for every kind of content
Vietnamese subtitling runs from corporate and eLearning through to streaming and social, and every one of them ends up in a different player. These are the formats 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.
Brief review
We review your video, your audience and the player, checking that stacked tone marks are not clipped by the line height.
Template and translation
Where needed, we create an English subtitle template first, then send it to a native Vietnamese subtitler.
Timing and quality checks
Subtitles are timed against the video and checked for reading speed, line length, diacritic rendering, and format compliance.
Delivery and display check
Files delivered in the format you need, with the stacked diacritics checked for clipping.
Our standards
The specs we work to
Readable subtitles are a matter of measurable limits, not opinion. These are the defaults we apply to Vietnamese unless your style guide says otherwise.
Maximum per line
37 for broadcast delivery
Maximum on screen
Line spacing set for stacked marks
Reading speed
Lower for children's content
Minimum duration
Seven seconds maximum
Vietnamese also tends to use more, shorter words than English rather than fewer long ones, which affects where lines can break and how much fits comfortably in a subtitle box. The character limits above hold, but they are filled differently: a Vietnamese line reaches them across more words, and the break has to land between them rather than wherever the count runs out.
Deliverables
Professional subtitle formats
We adapt your existing translations into subtitle format or create subtitles from scratch, in Vietnamese, English or any other language. And if the project needs a timed script or a plain document instead, we deliver that too.
Standard text-based
Compatible with most platforms and players.
Broadcast & professional
For broadcasters, post houses and streaming delivery specs.
Burnt-in video
One file, with the Vietnamese subtitles burnt into the frame.

Vietnamese specifics
North and south, and what the display check actually is
For written subtitles the standard is shared and one file serves the whole country. The differences between northern and southern Vietnamese are most audible in pronunciation, with some vocabulary variation, and they matter far more for voice over than for subtitling. Where content is strongly regional in tone, we will raise it.
The check that matters more is technical. Because the tone and vowel marks sit above the line rather than inside it, a Vietnamese subtitle needs vertical headroom an English workflow never thinks about — and that headroom disappears in the player, not the editor. So we test the file where it will be watched: the substituted font, the line spacing, and whether ể still reads as ể at viewing size.

Most common questions
Do I need northern or southern Vietnamese?
For written subtitles the standard is shared and one file serves the whole country. The differences between northern and southern Vietnamese are most audible in pronunciation, with some vocabulary variation, and they matter far more for voice over than for subtitling. Where content is strongly regional in tone we will raise it.
Will the Vietnamese diacritics display correctly on my platform?
That is what the final check is for. Vietnamese stacks a vowel mark and a tone mark on the same character, and both sit above the line, so tight subtitle line spacing can clip them — in which case the word on screen is a different word, not an untidy one. We confirm the file in the environment it will play in, and where a platform cannot be relied on to substitute a font that carries the full character set, burnt-in captions settle it at delivery.
Do you produce SDH and closed captions in Vietnamese?
Yes. Alongside standard subtitles we produce files that include sound effects, music cues, and speaker identification for deaf and hard of hearing viewers, formatted to the specification your platform requires.
How quickly can a Vietnamese subtitling project be delivered?
A short video is normally back with you inside 24 to 48 hours. From there it depends on whether we transcribe the Vietnamese audio before we translate, the number of formats leaving with the job, and the length of the finished cut. Your project manager gives you a firm date at the start.
How much does Vietnamese subtitling cost?
Vietnamese subtitling is billed per minute of finished video, from £20. Confirming that the diacritics survive the journey to the player is part of the work; it also turns on running time, transcription, SDH or burnt-in delivery, and the count of output formats. We quote every job on its own, and the Price Match Promise applies.
We already have a Vietnamese transcript — can you use it?
Happily. Where you already hold a transcript or SRT, we spot from that, checking that the Vietnamese characters have survived whatever encoding the file has been through — stripped or mangled diacritics are the most common thing we find. Otherwise we transcribe the Vietnamese audio first. The same two-stage QA, linguistic and technical, covers every file.
Can we drop your Vietnamese subtitle files straight into our edit?
The standard set, and the awkward ones: SRT, VTT, STL and TTML that keep the full Vietnamese character set intact into Premiere Pro, Final Cut Pro, DaVinci Resolve and the major online editors — or burnt into the picture as a finished MP4/MOV.
Do you also add same-language Vietnamese captions, not just translated subtitles?
Yes. As well as translating into Vietnamese, we produce same-language Vietnamese captions and SDH — the closed captioning teams need for accessibility, social video and search. If your footage is already in Vietnamese and you just want accurate on-screen captions with the diacritics rendered correctly, that is a core part of our Vietnamese captioning service.
What do you need from us to quote Vietnamese subtitling?
Less than people expect: the video, or a link to it, its running time, which platform or broadcaster it is going to, and the date you need it by. A rough cut is fine — we would rather quote on what exists than wait for picture lock and lose a week of your schedule. A named project manager comes back with an itemised quote, normally within four working hours.
How quickly will we hear back, and who will we be dealing with?
More than half of enquiries get a reply within thirty minutes during office hours (Monday to Friday, 9am to 6pm UK time), and the itemised quote normally follows within four working hours. After that you have one dedicated project manager who owns the job from brief to final file — not a ticket queue, and not a different name on every email. If it is easier, call +44 207 095 5730 and ask for them by name.
We are still pitching and the budget is not signed off. Can we still get a Vietnamese quote?
Yes, and it is one of the commonest reasons people get in touch. Tell us it is for a pitch and you get a figure you can put in front of your own client, itemised so it stands up to being picked apart, with no obligation and no follow-up sales calls if the pitch goes elsewhere. If it lands, the quote still holds and we already know the project.
What if we find a cheaper Vietnamese quote somewhere else?
Send it over. Our Price Match Promise covers like-for-like work, and because our quotes are itemised you can see exactly what is being compared — which is usually where the gap turns out to be, in a revision pass, a licence or a delivery format that the cheaper figure quietly left out. If it really is the same work for less, we match it.
