Video subtitling guidelines

Introduction

First News aims to be as accessible and usable as possible for every user. Our videos are subtitled for the hard of hearing, for people who have English as their second language or for anyone who wants to watch with the sound off.

  • First News subtitles are produced by Access Subtitling, who have 20 years’ experience working for all the major broadcast channels – BBC, ITV, Channel 4, Channel 5 and Sky – as well as films and DVD. They have supplied the guidelines below for generating subtitles on First News Live.

Subtitle guidelines summary

  • Timing: At least two seconds for one line of text and at least 3.5 seconds per two lines of text.
  • Grouping: Keep a natural grammatical structure so the viewer can understand each subtitle line before it disappears.
  • Style: Generally use 42 characters per line, with a maximum of 44 to avoid awkward subtitle breaks or very fast subtitles.
