Accessible Video (implementation guide)
The Video Accessibility Implementation Guide serves as support for the Video Accessibility Checklist. The order of the aspects and the structure according to categories are the same.
Each aspect is divided into three sections in the implementation guide:
Under the heading "What is meant by this?" you will find a detailed description of the aspect to be ticked off. The section "Why is it important?" describes which barriers you are removing with the respective aspect and for which groups of people this is essential. Finally, under the heading "How can I implement/check this?" you will find detailed instructions on how to implement or check the respective aspect.

2.4. Subtitles
Subtitles describe acoustic information.
What is meant by this?
Subtitles should be used in videos to provide the spoken content in written form. These subtitles serve as visual support and reproduce the spoken text verbatim. If necessary, they can also describe background noises, music or other auditory information.
Why is it important?
The use of subtitles describing acoustic information supports staff, people who are dependent on visual information or require visual support to process information. This applies, for example, to people with hearing impairments who cannot or can only partially understand the spoken content, as well as staff, people with learning difficulties or cognitive impairments who benefit from additional visual cues.
How can I implement/check it?
To ensure that subtitles adequately describe acoustic information, the following measures can be taken:
- Accurate transcription: Create an accurate transcription of the spoken content that includes background noise, music or other relevant auditory information.
- Clear formatting: Make sure that the subtitles are clear and easy to read. Use an appropriate font size and colour and ensure sufficient contrast between the subtitle text and the background.
- Timing and synchronisation: Make sure that the subtitles are displayed in sync with the spoken content and that they have enough time to be read.
- Comprehensibility: Use a precise and appropriate subtitle that corresponds to the auditory information.
