Tips for subtitling

  • Always check if the subject has already been translated into the language you require, this might mean there are established ways to spell product names etc. Where possible, provide a glossary list of these, so we can inform our translators.
  • Make sure the video you provide us with is final, as all of the translated content and timings will have to be redone at an extra cost if they change in the middle of the project.
  • It is always best to transcribe the video with time-codes in the original language first and only then translate, so only one set of time-coding needs to be done. If not, then we have to time-code each language individually, meaning extra costs and longer turnarounds.
  • If you’re planning on shooting raw footage in a language you are unfamiliar with and editing it later, please ask your guide or interpreter if they can give you a written transcript of everything that was recorded.

Subtitle styles
The above Portuguese subtitles were ‘burnt on’ to the video (open captions) and due to the nature of the video we used white text with an outline or shadow. There are various ways of producing subtitles to display on your video. We can advise you on the best option for yourselves and even provide samples for you to choose from. We can also advise on the best fonts to use too.

Portuguese SRT Subtitle Translations

In Portuguese subtitling translation, our Portuguese audiovisual translator would translate using the source video, producing SRT files that can then be used to create burnt-on Portuguese subtitles. SRT files are time coded documents that can be imported into the subtitling software which then puts the correct subtitle with the correct sequence, after this, there is only a visual tidy up required.

Using Adelphi’s Portuguese translation services for subtitling means quality and timing can be closely controlled throughout the project, ensuring that your subtitles will always be ready to publish on or before your deadline. We also provide Portuguese subtitling for translation agencies around the world and are happy to work with their translations. Adelphi is a proud member of the Association of Translation Companies (ATC).
