Audiovisual translation services adapted to your media

Nowadays, audiovisual is essential to your international communication. Audiovisual is a generic term that covers a variety of media ranging from the institutional film to the e-learning module. All these materials require adaptation using specific techniques.


Voice-over is the term used when the narrator doesn’t appear on screen. Also known as “off-camera” or “off-stage commentary”, this format allows you to add the voice of a person who does not play a part in the scene. In other words, it is not a visible protagonist who speaks, but a commentator or an external narrator, who provides explanations of the actions taking place on-screen.

Voice-over translation/dubbing

Voice-over translation consists of adding a voice over the original track. In other words, what the on-screen person is saying is still audible, but it is the dubbing actor’s voice that you hear the most. The advantage of this format compared to subtitling is that the viewer doesn’t have to look downwards to read the text as it comes up at the bottom of the screen. It is a better format for documentaries and corporate films.


This very flexible format is easy to circulate (you can send your employees the original file with the subtitles). It has the advantage of being less expensive and is suited to mobile internet use. Subtitling is a specific translation exercise that requires different skills from those necessary for traditional translation. For example, it is essential to be more concise for subtitling. Linguists with audiovisual expertise adapt the text to the constraints of the medium: number of characters per second (and per line), length of sentences, spacing of subtitles (in milliseconds), etc.


Using a combination of technology and human input, transcription is based on the automatic identification of audio sequences that are then checked by our linguists in order to produce a high-quality transcription. The aim is to subsequently launch the subtitling and dubbing process. But that’s not all: product texts can also be reused to improve the accessibility of your content, for example, for listeners who are deaf or hard of hearing, who will be able to read a perfect transcript of your video.

Do you have a subtitling project? Our methodology

We work with you to provide you with a perfect audiovisual translation, in line with your expectations and those of your target audience.

Our teams do the spotting, a step which consists of breaking down the dialogue into subtitles and defining the entry points (start of display) and exit points (end of display) using specific software. This means time-coding the source file so that it can receive the subtitles and fixing the number of characters per line, the display duration, etc. for the audiovisual translator. It’s a job that requires particular technical skills and a high level of accuracy.

Depending on amount of speech, this step can take a few hours for a short video, and up to a few days for a film. Once the initial spotting phase has been completed, we send your text to our professional audiovisual translators, whose target foreign language is their mother tongue. Lastly, we embed the subtitles in your video file or deliver a separate subtitles file depending on your requirements.
