About Sinhala subtitling

Sinhala is stored in one order and drawn in another

Around 18 million people read Sinhala, almost all of them in Sri Lanka, where it is one of the country's official and national languages. For a subtitle, the interesting part of the language is not its vocabulary. It is the writing system: an abugida whose vowels are written as marks on the consonant, above it, below it, after it or in front of it, which means the order in the file is not the order on the screen.

Take the kombuva, U+0DD9. It is typed and stored after its consonant and it is drawn to the left of it. Four further vowel signs are split marks that come apart into two pieces and land on either side of the letter. None of this is ornament a renderer may skip. The sequence has to be reordered before anything is drawn, and software that lays glyphs out in stored order gets Sinhala visibly wrong.

A native Sinhala subtitler writes the text, and at GoLocalise it is then looked at twice: once for the language and once for the way it renders. That second pass is the one that catches a conjunct which has quietly come apart, or a vowel mark parked on the wrong side of the letter it belongs to. Sinhala transcription, recording scripts and document translation run through the same team.

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

Subtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for social feeds that autoplay muted — and in Sinhala the reordering happens once, at our end, with no later engine left to redo it.

  • Always visible
  • Reordering settled at our end
  • 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 Sinhala subtitles or same-language Sinhala captions and SDH — in whichever form your platform and audience require.

What we subtitle

Where Sinhala subtitles end up

The work runs across corporate video, eLearning, documentary and social for a Sri Lankan audience, and the display pass goes with every one of them. These are the formats that come through most often.

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 settle the player, the encoder and the font your Sinhala will be shown in, alongside whatever delivery spec the platform imposes on the file.

2

Template and translation

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

3

Timing and quality checks

Cues are timed to picture and measured for reading speed and for line width, then read back on screen to confirm that every vowel sign and every conjunct has landed where it belongs.

4

Delivery and display check

Files go out in the format you need, with the rendered result seen on the destination player rather than trusted to the file.

Our standards

The specs we work to

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

42characters

Maximum per line

House default, still to be validated

2lines

Maximum on screen

Break between clusters, never inside

17chars/sec

Reading speed

Lower on children's programmes

1second

Minimum duration

Seven seconds at the outside

**No platform has published a style guide for Sinhala**, so these four are our own defaults carried over from Latin-script work, and we treat them as open to validation against your broadcaster's spec rather than settled. We also apply them to the line as drawn rather than to the string in the file, and that distinction earns its keep here: a mark stacked over a letter adds no width at all, while a split vowel sign adds width on both sides of it.

Sinhala specifics

Reordering, split vowel signs and the engine in between

The shaping specification for the script states it flatly: prebase vowels and the prebase components of split vowel signs reorder to the start of the cluster, and a Sinhala font's lookups have to be written against the sequence that comes out of that reordering rather than the one that went in. Four features are required of the font before a single word can be drawn correctly. What a viewer ends up seeing is decided by the engine between the file and the glass.

The four split signs, U+0DDA, U+0DDC, U+0DDD and U+0DDE, are taken apart by the shaping engine before any font feature runs at all, and the halves are then placed independently. Conjuncts lean on the same machinery: an al-lakuna followed by a zero-width joiner is what tells the font to hide the virama and bind two consonants into one form. Strip that joiner out in a routine clean-up and the bound form quietly comes undone.

So the check that counts is the one done on screen. We load the finished file into the player or the encoder it is heading for and read it there, because a font missing a required feature raises no error at all — it simply draws something else instead. Burnt-in delivery gets the same treatment, since the burn-in tool runs a shaping pass of its own and can reach a different answer from the player you tested in.

Most common questions

Why do some Sinhala vowel signs appear in front of the consonant they belong to?

Because that is how the script is read, even though the file keeps them the other way round. The kombuva, U+0DD9, is typed after its consonant and drawn to the left of it, and four other vowel signs come apart into halves that sit on either side of the letter. A shaping engine reorders the sequence at display time. Marks turning up in odd positions point at that engine rather than at the subtitler.

Will our player draw the conjuncts the way they should look?

That depends on the font and the engine behind it, which is exactly why we test instead of assuming. A Sinhala conjunct is formed by an al-lakuna and a zero-width joiner, and the font has to carry the substitution features that act on that pair. We open the delivered file in the player or encoder you name and read the result there. Tell us the target at the brief and the check is built into the job.

Can you supply burnt-in Sinhala subtitles we can trust on any device?

Yes, and burn-in is often the calmer route for this script. Once the text is part of the picture the reordering has already happened at our end, and every downstream player is simply playing video. We render the master, watch it back, and confirm that clusters, split vowel signs and bound consonant forms are drawn correctly. You get the master as MP4, MOV or ProRes with the Sinhala fixed in place.

Is there a published subtitling standard for Sinhala?

Not one we can point you at. The platform style guides published for South Asian languages cover Tamil, Telugu, Malayalam, Kannada, Marathi, Hindi and Bangla, and Sinhala is not among them. So we publish our own defaults and say plainly that they are defaults: forty-two characters, two lines, seventeen characters a second, one second minimum. Where your broadcaster sets a spec of its own, that wins and we build the file to it.

What is the per-minute rate for Sinhala subtitling?

The rate opens at £20 for each minute of video, and the display checks this script needs sit inside that figure rather than on top of it. Running time drives most of the total. A transcript, an SDH pass, burnt-in output and each further delivery format push it up from there. Pricing is itemised per job, and our Price Match Promise stands behind whatever we send you.

When the audio is already Sinhala, can you simply caption it?

That is standard work here. Where the soundtrack is already Sinhala we caption it in Sinhala, adding SDH where speaker labels and sound description are wanted, which is what accessibility teams generally ask for and what keeps a video usable in a feed playing without sound. A transcript is produced first, and the display pass runs on those files exactly as it does on translated ones.

Our Sinhala SRT was made elsewhere. Is it usable?

Usually. Your file becomes the starting point: we re-spot it to picture, adjust any line running long once it is drawn, and restore joiners that a previous export has dropped. Flag it early if the text has been through a converter or a legacy font, because those arrive with clusters already broken and take longer to put right. Where no transcript exists at all, we write one from the audio.

Which editors will these Sinhala files open in?

The usual set. Our VTT, SRT, STL and TTML deliverables open in DaVinci Resolve, Premiere Pro, Final Cut Pro and the browser-based editors with the Sinhala intact. They will not all shape the text identically, though, so if the edit suite is where the subtitles end up being burned in, say so and we will check what comes out of that suite as well.
