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.
1. Audio track
1.3. Relevant information
Relevant information can be perceived auditorily.
What is meant by this?
It is of great importance that the sound and speech in videos are clear and distinct to ensure that all relevant information can be perceived and understood acoustically. To ensure this, it is important that information is not only presented visually, but also aurally.
Why is it important
The provision of audibly perceptible information in videos ensures that staff, people who primarily absorb information acoustically, have approval of the content. This applies in particular to people with visual impairments or those who cannot fully understand visual content.
How can I implement/check it?
To ensure that relevant information in videos is audible, the following measures can be taken:
- Clear sound recording: Make sure that the sound in the video is of good quality and does not contain any background noise or breakdowns. Professional recording equipment and a high-quality microphone are recommended for this.
- Clear language: The person presenting the information in the video should speak clearly and distinctly. Appropriate intonation and speaking speed are also important.
- Check the sound quality: Test the video on different devices and in different environments to ensure that the sound is audible to all viewers.
- Filter noises: Video programmes often offer the option of filtering sounds and subsequently removing background noise.
- Audio description: Depending on the software, it is possible to switch optional audio descriptions on or off.
- Test: It is advisable to watch the video once without visual support to check whether all important information is conveyed audibly.
