Captions / subtitles
We create captions for video: accurate synchronized text of speech (and important sounds) — for deaf and hard-of-hearing users, and for those watching without sound. So that video is clear without sound, rather than losing part of the audience. Honestly upfront: quality captions are human work with checking and synchronization; auto-captions (auto-recognition) are only a draft with errors, especially on terms, accents and noise. The cost depends on duration, and each language is separate.
Captions / subtitles — overview

Captions for video is the creation of accurate, time-synchronized text of what sounds in the video: lines, speaker names if needed, and important non-speech sounds (e.g. '[laughter]', '[phone ringing]') for the full picture. We do it for deaf and hard-of-hearing users (a WCAG accessibility criterion), and also for those watching without sound (metro, office) — there are many such now. Honestly about quality, this is key: good captions are HUMAN work: transcription, correct punctuation, accurate synchronization with speech, a readable pace. Automatic captions (YouTube auto-recognition, etc.) are only a DRAFT: they err on terms, names, accents, with noise and multiple speakers, and publishing them as 'accessibility' without checking is dishonest. We can take auto as a base, but finish it manually. Honestly about volume: the price depends on the DURATION of the video (minutes) and complexity (number of speakers, terminology). Honestly about languages: captions in each language are separate work (translation+synchronization); one set of captions ≠ all languages. Honestly about the process: new videos require new captions — this is maintenance. Honestly about the boundary: captions convey speech and sounds as text, but that is not the same as audio description of the visuals for blind users (814) — different tasks for different needs. Honestly about the effect: accessibility + retention of those without sound; we do not guarantee direct sales growth. Honestly about access: source videos are needed. An important boundary: this is captions for video; transcripts of audio are 812, audio description is 814. Picture this: instead of 'without sound the video is useless, and deaf users are excluded' — text synchronously accompanies the video. The base price starts from 15,000 ₽ (depends on duration; each language separate).
Problems we solve
- Deaf and hard-of-hearing users do not understand the video — no captions.
- Without sound (metro, office) the video is useless — audience is lost.
- Auto-captions with errors on terms, names and with noise.
- Captions are out of sync and unreadable by pace.

FAQ
Auto-captions can just be turned on — why pay?
Auto-captions are a draft: they err on terms, names, accents, with noise and multiple speakers. Publishing them as 'accessibility' is dishonest — a deaf user gets distorted meaning. We can take auto as a base, but finish it manually: transcription, punctuation, accurate synchronization. That is real accessibility.
Will you make captions in all languages at once?
Each language is separate work: it is translation plus its own synchronization. One set of captions does not cover all languages. Tell us the needed languages — we will calculate honestly for each; it is usually more reasonable to start with the main one and the language of the key audience.
Is this the same as audio description?
No, different tasks. Captions convey speech and important sounds as TEXT — for those who cannot hear. Audio description (814) — conversely, describes the visual events by VOICE for blind users. These are needs of different groups; we will honestly say what you need and whether you need both.
