Generally speaking, subtitling consists of providing a written text at the bottom of the screen that reproduces the actors’ dialogs as well as giving an account of any discursive elements that form part of the photography or soundtrack. Viewers who, as the case may be, are not speakers of the content's language or who have problems understanding an accent, can follow the dialogs spoken by the characters via a text inserted onto the screen.

At SeproTec, we have a team of professionals who translate and abbreviate the texts by applying subtitling techniques and they then insert the subtitles into the video using specifically designed subtitling programs.

We also adapt the subtitles so as to both guarantee their quality and comply in full with the directives and specifications of the new subtitle and video files depending on the target country.

We offer a complete solution that is secure, transparent and flexible for any type of project in any language combination.
