Subtitling translation services

LinguaVox provides subtitling translation services for media production companies, international brands, education institutions and corporate communications teams. Since 2000, we have managed multilingual media projects in more than 150 languages, with a focus on the technical precision required for synchronised text. Whether you need subtitles for corporate training videos, promotional content or educational material, we provide the linguistic support needed to reach international audiences.

Subtitling is a technical discipline that goes well beyond translating text. It requires careful control of timing, reading speed, line length and the natural flow of text on screen. Each project is assessed according to the source language, target language, visual content of the video and required final format. We assign every project to a linguist who understands both the linguistic requirements of the target market and the technical constraints of professional subtitling software.

The technical subtitling process

Professional subtitling is constrained by the viewer's ability to read and watch simultaneously. Our process focuses on creating subtitles that are easy to follow without distracting from the video's visual content.

This involves several practical factors:

• Synchronisation: Subtitles follow the speech closely and remain on screen long enough to be read.
• Reading speed: We apply agreed characters-per-second limits so the audience has adequate time to read the text.
• Line length: Subtitles are kept within established character-per-line limits to avoid cluttering the screen or wrapping text awkwardly.
• Layout: Subtitles are positioned so they do not cover essential visual information.

Documents and media formats

We support a wide range of audiovisual media formats. Common project materials include:

• Promotional corporate videos and advertising spots.
• Educational, training and e-learning media.
• Conference recordings and webinar materials.
• Multimedia content for web platforms.

We encourage clients to provide the source video or a clean transcript before translation begins. Where no transcript exists, we can provide professional transcription services to create the source text first. We deliver subtitles in standard industry formats — including SRT, VTT and STL — making it straightforward for your production team to integrate the text into your editing software.

Workflow and quality checks

Our subtitling workflow is built around linguistic accuracy and technical synchronisation. Following the initial translation, the project undergoes independent bilingual revision. During this stage, a second professional linguist compares the target text against the original audio, checking the translation's meaning, synchronisation, timing and formatting so the final output can move to production review.

Our project managers then carry out a delivery review to confirm that all files meet the agreed technical specifications and that the language is consistent across any multilingual versions of the same video.

Adaptation for international markets

Subtitling is an efficient way to reach an international audience without the cost of a full dubbing production. Cultural adaptation still matters, however. Our translators focus on adapting idioms, references and humour so they land correctly with the local audience. A cultural reference that is immediately clear in the UK may require adaptation to be understood by viewers in other regions.

We also take account of local conventions regarding subtitles. Some markets prefer concise summaries; others expect a closer rendering of spoken audio that preserves pauses and speaker changes. We confirm the approach before starting so that the final subtitles are appropriate for your intended audience. For e-learning and training content, consistency between subtitle text and any on-screen text is also checked, because inconsistencies between the two are a common source of confusion for learners.

Requesting a reliable quote

Send the source video, a transcript if available, the target languages, your required deadline and the final format you expect to receive. Also state if your video is intended for a specific platform — such as YouTube or a corporate intranet — that may have its own technical requirements.

Word count is a factor, but the number of speakers, the pace of delivery, the complexity of any technical terminology and the need for timing revision will determine the scope of the project.
