Subtitling involves the adoption of video dialogue to written speech or presentation and includes the rhythm of speech and register. It improves comprehension and builds up vocabulary. Subtitles are condensed and summarised versions of what is being spoken and are often limited to 2 lines of text that are generally positioned at the bottom of the screen. Each line must be 35 characters or less and a maximum duration of 6 seconds on screen for effective reading whilst watching the video content of the speaker.

Subtitles to social media videos are currently in high demand as it allows videos to be auto played and reduces any forms of distraction when in the company of others. Subtitling services are not just for the translation of languages, they can be used for the deaf or hard of hearing, to listen to when the reader is in an environment with loud background noise or for note taking on education videos. In addition, subtitling is effective for businesses as it boosts search engine optimisation (SEO) meaning your videos can be discovered more easily online.
