About English subtitling

English subtitles, captions, and SDH, done to spec

English subtitling can mean subtitling for viewers who can hear the audio but are watching without sound, reading in a second language, or following dialogue that is hard to catch. Then there is captioning and SDH for deaf and hard-of-hearing audiences, which adds sound effects, music cues, and speaker identification, and which can form part of your accessibility obligations.

English files also carry a second role in multilingual projects. The English subtitle template is what every other language version is built from, so any timing error, awkward break, or ambiguity in it propagates into every language downstream. Getting the English right first is the cheapest quality control there is.

At GoLocalise, we produce English subtitles, captions, and SDH to the specification your platform requires, 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

The English text lives in the image itself. It cannot be turned off, so it still reads on a feed that autoplays with the sound down.

  • Always visible
  • Font, size, colour and placement set to your brand guidelines
  • 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 English subtitles or same-language English captions and SDH — in whichever form your platform and audience require.

What we subtitle

English subtitling for every kind of content

English subtitling spans everything from corporate training to streaming and social — often as same-language captions for accessibility rather than translation. 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 whether you need subtitles, closed captions, or SDH.

2

Transcription and spotting

Dialogue is transcribed and cued against the video, with in and out points set to the speech.

3

Timing and quality checks

Files are checked for reading speed, line length, break points, and compliance with your platform's specifications.

4

Delivery

Your English subtitle files in the exact shape your platform expects, on budget and on time.

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

Automatic captioning produces a rough transcript quickly and is useful as a starting point. What it does not produce is a broadcast-quality file: speaker changes go unmarked, sound effects are missing, proper nouns and technical terms come out wrong, and lines break where the software runs out of characters rather than where the meaning allows. Every file we deliver is produced and checked by a professional subtitler.

English specifics

Compliance, and the file every other language is built from

Whether you need captions depends on where you are publishing and who you are. Broadcast regulators, public sector accessibility rules, and the major streaming platforms each set their own captioning requirements, and the WCAG accessibility standards are widely referenced for web content. We can advise on what applies to your distribution, though the compliance decision remains yours.

The second consideration is downstream. Translators work from the English template, so its timings, segmentation, and phrasing carry into French, Japanese, Arabic, and everything else in scope. An ambiguity left in the English becomes a translation error repeated across every language you deliver, which is why we treat the English file as the foundation of a multilingual project rather than one deliverable among many.

Most common questions

What is the difference between subtitles, closed captions, and SDH?

Subtitles carry the spoken dialogue and assume the viewer can hear everything else. Closed captions are made for viewers who cannot hear the audio and include sound effects, music cues, and speaker identification. SDH is subtitling for the deaf and hard of hearing, and it combines the two: dialogue plus the non speech information, formatted like subtitles rather than broadcast captions. Which you need depends on your audience and your distribution route.

Do I legally need captions on my content?

It depends where you are publishing and who you are. Broadcast regulators, public sector accessibility rules, and the major streaming platforms each set their own captioning requirements, and the WCAG accessibility standards are widely referenced for web content. We can advise on what applies to your distribution, though the compliance decision remains yours.

Why does the English subtitle file matter for other languages?

Because it is the source every other version is built from. Translators work from the English template, so its timings, segmentation, and phrasing carry into French, Japanese, Arabic, and everything else in scope. An ambiguity left in the English becomes a translation error repeated across every language you deliver.

Can automatic captioning tools do this?

They produce a rough transcript quickly and are useful as a starting point. What they do not produce is a broadcast-quality file: speaker changes go unmarked, sound effects are missing, proper nouns and technical terms come out wrong, and lines break where the software runs out of characters rather than where the meaning allows. Every file we deliver is produced and checked by a professional subtitler.

How quickly can an English subtitling project be delivered?

Twenty-four to 48 hours covers most short videos. What changes it is how many output formats you need, whether we transcribe the English audio before we translate, and how long the video runs. Your project manager pins the delivery date down at the brief.

How much does English subtitling cost?

English subtitling is charged by the running minute of video, with the drivers being running time, whether we transcribe or spot from scratch, whether you are taking SDH or burnt-in delivery, and how many formats you want. Because English is compact it condenses less than most languages, which often keeps spotting straightforward. Each project gets its own quote, with the Price Match Promise behind it.

Do you add same-language English captions and SDH, not just translated subtitles?

Yes. A lot of English subtitling is same-language captioning — closed captions and SDH for accessibility, social video and search rather than translation. If your video is already in English and you just want accurate on-screen captions or SDH with speaker IDs and sound cues, that is a core part of our English captioning service.

Can you start from an English SRT file we already have?

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

Which editing software do your English subtitle files import into?

Every common one. We deliver English 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.

What do you need from us to quote English 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 an English 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.
