Accessibility guidelines like the WCAG, or other similar best practices, provide detailed information about how to implement videos to make them technically accessible. Thanks to these documents, we understand the need for captions, sign language versions, and sufficient audio contrasts to accommodate the needs for users with auditory impairments.
However, these guidelines say nothing about how to shoot, edit, or post-product a video, in order to make it more understandable or usable by people with different abilities. Which is logical with regards to the technical orientation of the WCAG and their spawns: this “editorial” aspect of making videos not being in their scope. Yet, video makers, through their design choices, can influence the overall accessibility of video content. This presentation aims at proposing hints and tips to video makers, answering questions like:
- Which fonts are best suited for captions and on-screen texts?
- How to select voices in order to optimise audio contrasts?
- Which angles or framing are preferable?
- How to insert a sign language version?
The layout of the presentation:
- Understanding the different types of hearing impairments
