One source SRT became six market-ready files with timing untouched. Our agency quoted two weeks for the same job.
English → Vietnamese · timing preserved: Translate Subtitles from English to Vietnamese
Vietnamese stacks tone marks on its letters and chooses pronouns by age and relationship, which English never does. Upload an SRT, VTT or video and get Vietnamese captions with every diacritic in place and the original timing intact.

What Changes When English Becomes Vietnamese
Three things worth knowing before you ship Vietnamese captions.
Vietnamese uses six tones, written as marks above and below the vowels, often two on a single letter. A missing or wrong mark does not just look careless, it turns the word into a different one. Subtitles have to keep every diacritic intact from translation through export, and the font that displays them has to support all of them.
English uses I and you for everyone. Vietnamese picks pronouns from family terms according to age, gender and relationship, so a manager addressing staff, a host speaking to viewers and two friends talking each need different words. The choice has to be made from context and kept consistent through the video.
Vietnamese writes each syllable apart, so a two-syllable word looks like two words. Lines tend to come out longer than English in characters, and a line break must never separate the syllables of one word or a name. Breaking at phrase boundaries keeps captions easy to read.
One English cue, translated into Vietnamese
Vietnamese adds characters and carries its meaning in tone marks.
- 00:00:01,600 → 00:00:04,100
English: Please upload your video to begin.
Vietnamese: Vui lòng tải video của bạn lên để bắt đầu.
- 00:00:04,500 → 00:00:07,000
English: The meeting has been moved to next Tuesday.
Vietnamese: Cuộc họp đã được dời sang thứ Ba tuần sau.
The first line grows from 34 to 42 characters, because each syllable is written separately. In the second, Tuesday becomes the third day of the week, and the line keeps every tone mark the meaning depends on.
English → Vietnamese, Done Right
Vietnamese needs every mark in place; the timing stays exactly where it was.
Every tone mark intact
Diacritics survive translation and export, so no word changes its meaning along the way.
Pronouns that fit the speakers
Forms of address are chosen from context and kept consistent across the whole file.
Cues keep their English timing
Vietnamese lines inherit the start and end time of each English cue, so nothing has to be re-synced.
Line breaks checked in context
Each Vietnamese line sits next to its English source, so a break inside a word or a name is caught before export.

Rated Excellent 4.8/5 based on 580+ reviews
Uploaded a two-hour recording during lunch — the transcript was waiting before I finished my coffee. The accuracy genuinely surprised me.
Our legal team approved it because processing stays on EU infrastructure. That alone ruled out most of the competition.
Seeing source and translation together makes QA fast. We ship subtitles the same day we cut the video.
No card, no tricks — I tested real files before paying and upgraded a week later because the workflow stuck.
Had trouble with a huge file — support walked me through batch upload the same morning. Rare these days.
Upload your English SRT or VTT file, or the video itself, and choose Vietnamese as the target language. BlaBlaScribe translates every line with AI and keeps the original timestamps, so the Vietnamese subtitles stay in sync with the speech. Fix the wording in the editor, then download SRT or VTT or export an MP4 with the subtitles burned in. Translation is available on paid plans from $14 a month.
Yes. SRT and VTT files are written in UTF-8, so every diacritic, including letters that carry two marks, comes through intact in any current player.
From context: who is speaking, to whom, and in what setting. A presenter addressing viewers and two friends chatting get different forms, and the choice is held consistently. Every line stays editable next to the English original.
In characters, usually yes, because each syllable is written as a separate word. Lines are phrased to stay inside two readable lines, and you can trim any of them in the editor before export.
Common streaming guidelines allow about 42 characters per line and two lines per cue. Lines are broken between phrases, never between the syllables of one word.
Yes. Pick a caption style and export an MP4 with the Vietnamese subtitles burned in; it renders in your browser. Choose a style whose font supports Vietnamese diacritics and check the preview first.
