Why Multilingual Subtitling & Closed Captions Matter

Adding multilingual subtitles and closed captions to your videos brings clear communication and commercial benefits:

  • Reach wider international audiences by making content accessible in multiple languages
  • Improve video SEO, as subtitles allow search engines to index spoken content
  • Increase viewer engagement, especially on mobile and social platforms where videos are often watched without sound
  • Enhance accessibility for deaf and hard-of-hearing audiences
  • Improve comprehension and retention across global markets

Professional subtitling helps ensure your message is understood clearly, consistently and inclusively – regardless of language or platform.

We support a wide range of video content types and delivery channels, including:

  • Marketing and advertising videos, helping brands engage audiences across markets
  • Corporate and internal communications, ensuring clear messaging for global teams

Our experienced linguists follow professional subtitling best practices, ensuring accurate timing, line length, reading speed, and on-screen display, while maintaining tone and meaning in every language. We work with SRT and other industry-standard subtitle and caption formats to ensure compatibility and avoid timing issues across platforms.

Subtitles can be delivered as standalone subtitle files that viewers can turn on or off, or as burnt-in subtitles permanently embedded into the video.

Subtitle Translation & Closed Captioning Process

Our subtitling process is designed to deliver high-quality, readable subtitles across languages. Where required, or when no transcript is available, we first accurately transcribe the source audio before creating subtitles (.SRT or other formats) in line with professional subtitling and accessibility standards. These subtitles are then translated into the required target languages by expert linguists, followed by a final post-translation fit and quality check to ensure accuracy, timing, and consistency before delivery.
