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
These Thai subtitles were ‘burnt on’ to the video (also called open captions) and because of the nature of the video we used white text with an outline or shadow. There are many styles of subtitles to display on your video. We can advise you on the best type for your video and produce samples for you to choose from. We can also help with the best fonts to use as well.

Thai On-Screen Text Localization

We also localize any on-screen text and motion graphics etc. into Thai. Depending on the complexity and how the original was created we might need the original data package it was produced in.

Thai font problems
It is very important that the diacritics are correctly lined up otherwise the meaning can change. The correct font must be used to display the diacritics in the right position.

Thai to English Subtitling

Through our Thai to English Subtitling Service, we produce SRTs and open- and closed-caption subtitles in English from your original Thai video. We manage the entire process for you from start to finish, including transcription, translation, proofreading and subtitling.

Thai Subtitle Translations

For Thai subtitle translation, we would use a Thai audiovisual translator who will create translated subtitles in the target language directly from the video in the source language. The subtitle translator would produce SRT files that can then be used to create burnt-on Thai subtitles.

Adelphi Studio is part of Adelphi Translations Ltd. a full-service translation agency, not just producing Thai translations but also Thai typesetting and Thai voice-overs.

Using Adelphi’s Thai 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 Thai subtitling for translation agencies around the world and are happy to work with their translations. As some languages must use specific fonts in order to work with the subtitling software, we can consult with you about your needs and advise you of all of your options. Adelphi is a proud member of the Association of Translation Companies (ATC).

Transcription Services

We also offer a transcription service for those customers lacking a transcript of their videos. We provide time-coded scripts of your videos ready to be translated. We will then use those translations for the subtitle text, sending you the files at each stage of the process for you to review and assess.

Articulate Storyline Localization Service

We can translate not just the text from your Articulate Storyline course itself but also localize all of the button and slider content too, we also add voice-overs and subtitles to any embedded videos using translated scripts and voice talents we can provide.
