  3. Search and reuse

    How subtitle files can be indexed and reused every time a video goes to a new market.

  4. Your benefits

    Wider reach, better accessibility, more visibility in search and higher engagement.

  5. Content we subtitle

    Corporate communications, e-learning and training, marketing videos, social media posts, films and audio recordings.

    Transcription, translation, subtitle creation and delivery, with subtitles for the deaf and hard of hearing on request.

Who it's for

Marketing, communication and training teams that publish video for customers, partners or employees in several countries.

It is most useful when you are planning a video campaign abroad, rolling out training to international teams or reviewing how accessible your video content is.

Good to know

  • Subtitle files such as SRT or VTT are plain text, so they can be translated, stored in a translation memory and reused when a video is updated.
  • Subtitles for the deaf and hard of hearing add speaker names and relevant sounds, not just the spoken words.
  • Readable subtitles respect limits on line length and reading speed, so a translation often needs condensing, not just translating.
  • Automatic captions are a useful draft, but names, technical terms and timing usually need correcting by a linguist.

Frequently asked questions

What is the difference between subtitles and closed captions?

Subtitles usually render the dialogue for viewers who can hear but may not understand the language. Closed captions and SDH subtitles also describe relevant sounds and identify speakers for viewers who are deaf or hard of hearing, and closed captions can be switched on and off.

Are automatic subtitles good enough?

They are a fast first draft. For published content, a linguist should check accuracy, terminology, line breaks and timing, because errors in subtitles are visible to every viewer and can change the meaning.

Do subtitles help with search visibility?

Subtitle and transcript files give search engines text they can read, which can help video content be found. Translated subtitles extend that to searches in other languages.

Can subtitles be reused when a video changes?

Yes. Because subtitle files are text, approved translations can be kept in a translation memory, so an updated video only needs the changed lines translated and retimed.
