Video subtitling: professional translation, synchronization and preparation for publication
Nowadays, videos are often watched whilst traveling, at work, in public places or simply with the sound turned off. Companies are expanding into international markets, educational platforms are attracting audiences from different countries, and social media is changing audience habits daily. In this context, subtitles are no longer merely an addition to foreign films. They have become a fully-fledged communication tool.
- High-quality subtitles help viewers better understand the content, ensure they don’t miss important figures, names, or terms, and allow them to take in the information at a comfortable pace. For businesses, this also offers the opportunity to adapt existing videos for a foreign-language audience without the need for reshooting or a complete re-dubbing.
- However, professional subtitling is much more than just text at the bottom of the screen. It combines transcription, translation, editing, working with timecodes, and the technical preparation of the material.
What is subtitling?
Subtitling is the process of converting spoken language into structured text synchronized with the video footage. If the video is intended for a foreign audience, this involves translating and adapting the text into another language.
Typically, the work involves: Spoken language almost always contains repetitions, pauses, unfinished sentences and filler words. If transcribed verbatim onto the screen, the text will be overloaded. Therefore, the editor must remove the superfluous elements without distorting the speaker’s meaning, intonation or style.
- transcription of the audio track;
- translation of dialogue;
- linguistic and stylistic editing;
- dividing the text into blocks that are easy to read;
- creating and adjusting timecodes;
- preparing the file in the required format;
- where necessary, embedding subtitles into the video.
Where subtitles are used
Subtitling is needed wherever a video needs to remain understandable regardless of language, sound quality or viewing conditions.
Subtitles are produced for international companies: they allow a single video to be used in several countries. For educational projects, they help viewers better absorb complex information. On social media, on-screen text is often crucial: users understand the video’s topic even before they turn on the sound.
- films, TV series and documentaries;
- corporate presentations and announcements;
- online courses, lectures and webinars;
- advertising and promotional videos;
- YouTube, Instagram, TikTok, Facebook and LinkedIn;
- interviews, conferences and video podcasts;
- technical instructions;
- legal, medical and scientific materials.
Main types of subtitling
In-language subtitles are created in the same language as the video. They are useful for watching without sound, for educational purposes, and for the accurate rendering of titles, numbers and specialist terms.
Translated subtitles involve adapting the speech for a non-native-speaking audience. Here, the translator works not only with the meaning of the words, but also with line length, cultural context, idioms, and communication style.
Subtitles for people with hearing impairments can also convey important sounds: music, applause, background noise, a telephone ring or a change of speaker.
Subtitles are categorized as open or closed depending on how they are displayed. Open subtitles form part of the video image and cannot be turned off. Closed captions are loaded as a separate track, so the viewer can choose the language they need or watch without text.
Why automatic subtitles are not enough
Automatic recognition systems can speed up the initial preparation of the text. However, the results are rarely ready for immediate publication.
Algorithms often make mistakes with names, geographical terms, abbreviations, brand names, and specialist terminology. Difficulties arise due to background noise, accents, fast speech, several people speaking at once, or poor recording quality.
Machine translation does not always take context into account either. It may translate an idiom literally, fail to recognize irony, or suggest a term that is technically correct but not used in the relevant field.
There are also technical shortcomings: excessively long blocks, poor line breaks, text appearing too late or too early. Professional proofreading is essential to ensure that subtitles do not simply repeat the words, but genuinely help viewers to understand the video.
How professional subtitling works
First, a specialist reviews the material and clarifies the requirements: the source language, the target language, the target audience, the publication platform and the required format.
If there is no script, transcription is carried out. Particular attention is paid to numbers, dates, names, company names, medicinal products, equipment models and specialist terminology.
The text is then edited and, where necessary, translated. Long sentences are shortened, but not simplified to the point where the meaning is lost. Idioms, jokes and cultural references are adapted to suit the target audience’s understanding.
The next stage is segmentation and synchronization. The text is divided into complete semantic blocks, and the timing of their appearance and disappearance is determined. Speaking pace, reading speed, pauses and scene changes are all taken into account.
The finished material is reviewed at a normal pace. This allows us to spot things that aren’t always visible in the editor: lines changing too quickly, awkward line breaks, or conflicts between the text and the on-screen graphics.
Specifics of subtitle translation
Translating subtitles differs from translating a standard document. Screen space and the duration of a line of dialogue are limited, so a word-for-word rendering is not always possible.
The translator must simultaneously preserve the meaning, intonation, and natural flow of the language. At the same time, the text must be easy to read and must not obscure important elements of the video.
The logical division of lines is of great importance. One must not separate a preposition from the word it modifies, or split a noun, a fixed phrase or parts of a sentence in such a way that the meaning only becomes clear after the next subtitle appears.
Consistent terminology is essential for legal, technical, medical, financial and scientific materials. In a series of videos, it is advisable to use a single glossary, standardized spellings of names and common formatting rules.
Subtitle formats
The most common format is SRT. Most video players, editing programs and platforms support it.
VTT is often used for websites, online courses and browser-based video players. The ASS format is suitable for projects where you need to customize the font, color, size and other formatting parameters.
For television, professional media systems and streaming platforms, STL, TTML, DFXP or other specialized formats may be required.
Clients can also receive text with timecodes or a finished video with embedded subtitles. The best option depends on the method of publication, the number of languages and the ability to turn the text on or off.
What determines the cost
The price of subtitling is determined after reviewing the material. Videos of the same duration can vary significantly in complexity.
The cost is influenced by the duration and quality of the recording, the number of speakers, the speaking rate, the subject matter, the language pair, the availability of a finished script, and the need for transcription.
Additional factors taken into account include the output format, the number of language versions, the need to embed the text into the video, formatting requirements and the urgency of the project.
A preliminary review allows us to accurately determine the scope of work and agree on a price before work begins.
Quality control and confidentiality
The final check covers the accuracy of the transcription, the correctness of the translation, spelling, punctuation, terminology, timecodes and readability.
A separate check is carried out to ensure that the text does not overlap with logos, graphics, captions or the speakers’ faces. The file is tested in the relevant media player or on the platform for which it has been prepared.
Confidentiality is no less important. Unpublished presentations, internal training materials, negotiations, medical records or videos containing personal data are often submitted for subtitling. Access to such files is restricted to specialists involved in the specific project. Where necessary, confidentiality terms may be set out in a separate agreement.
