Subtitles play an important role in adapting audiovisual content for recipients all over the world. They make videos understandable for people who don’t know the source language and the deaf and hard of hearing, taking their viewing experience to a whole new level.
In turn, promotional content with subtitles – such as advertisements or shorts on social media – deepen viewers’ engagement to a considerable extent. What is more, subtitles can help memorise information, which increases the effectiveness of promotional campaigns.
Delegating the task to an amateur (or resorting to AI, which still has grave difficulties managing audiovisual content) may result in disinforming the audience or even offending some groups of recipients. Don’t take risks – turn to the professionals.
Same-language subtitles (SLS)

SDH subtitles – subtitles for the deaf and hard of hearing
Outbursts of laughter, murmurs of a river, or eerie door creak sounds – all those elements influence a video’s reception. SDH subtitles are meant for the deaf and hard of hearing; apart from offering the regular dialogue transcript, they specify the speaker (should they be off-screen), and include descriptions of background sounds, special effects, and even intonation – in other words, they provide all the information necessary to fully understand the context and the emotional load of a given scene.
Voice-over translation
A key element that streamlines voice-over recording is a meticulously prepared script. Our experienced translators will render the source content into another language and synchronise the resulting script with the video and audio.

FAQ
Audiovisual translation is a specialised field of translation that deals with multimedia content – films, TV series, corporate videos, advertisements, and social media content. It covers a range of services including subtitle creation, subtitle translation, voice-over translation, SDH subtitles for the deaf and hard of hearing, template creation, conformance, and linguistic and technical quality assurance.
Same-language subtitles (SLS) are prepared in the same language as the video’s audio track. They improve accessibility and comprehension – for example, for viewers watching in noisy environments or those who process information better when reading alongside listening. Translated subtitles, on the other hand, render the dialogue into a different language, allowing content to reach international audiences who do not speak the source language.
SDH stands for Subtitles for the Deaf and Hard of Hearing. Unlike standard subtitles, SDH versions go beyond dialogue transcription – they include descriptions of background noises, sound effects, speaker identification (when the speaker is off-screen), and even intonation cues. This gives deaf and hard-of-hearing viewers the full context needed to understand not just what is being said, but the emotional tone and atmosphere of a scene.
Yes. Each major streaming platform – such as Netflix, Disney+, Amazon Prime Video, Viaplay, or SkyShowtime – has its own technical requirements regarding character limits, line breaks, dialogue formatting, and file formats. Technical QA specialists verify that all subtitles meet the relevant style guide before delivery, ensuring the files are ready for direct use on the platform.
AI tools still struggle significantly with the nuances of audiovisual content – timing, speaker identification, idioms, cultural references, and tone. Errors in subtitles can disinform viewers, misrepresent your brand, or inadvertently offend specific groups of recipients. Professional AVT services, carried out by experienced native-speaker linguists with technical QA oversight, eliminate these risks and ensure the subtitles genuinely serve their purpose.
Conformance is the process of adjusting existing subtitles to a new or revised audio or video recording. If a film or video is re-edited, re-mixed, or otherwise changed after the subtitles have been created, conformance ensures that the subtitle timecodes remain in perfect sync with the updated version – without the need to retranslate the content from scratch.
The service covers a broad range of audiovisual formats: feature films, TV series, streaming platform content, corporate and training videos, promotional content, social media shorts, and game localisation. Each content type is approached individually, with processes and tools adjusted to suit the specific requirements of the format and the target platform.
Subtitles on promotional videos and social media content have a measurable impact on viewer engagement – they help viewers retain information more effectively and keep their attention on the screen longer. This directly improves the performance of marketing campaigns, particularly on platforms where videos autoplay without sound, making subtitles the primary way many users consume content.
