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. Video track
2.2. Mouth picture
The person speaking and the mouth image are clearly visible.
What is meant by this?
In videos, care should be taken to ensure that the person speaking is clearly recognisable and that their mouth image is clearly visible. This serves as visual support for the auditory information intake. By emphasising the mouth image, lip movements and mouth shapes, for example, can be better recognised, which makes it easier to understand the spoken content.
Why is it important?
The visual highlighting of the person speaking and their mouth image supports recipients who are dependent on visual cues when taking in auditory information. This applies in particular to people with hearing impairments who may be dependent on reading lip movements in order to better understand what is being said.
How can I implement/check it?
To ensure that the person speaking and the mouth image are clearly visible, the following measures can be taken:
- Camera settings: Make sure that the camera clearly captures the person speaking and that the mouth image is clearly recognisable. Avoid excessive zooming or unclear shots.
- Lighting: Ensure sufficient lighting so that the face of the person speaking is clearly visible. Avoid strong backlighting or shadows that could impair the mouth image.
- Emphasise mouth movements: The person speaking should take care to speak clearly and intelligibly. Emphasising mouth movements and pronunciation can help to make the mouth image more recognisable.
