Making Multimedia Accessible: 什么不起作用
The following list consists of the most common issues that make multimedia content inaccessible and quick steps for how to avoid them:
- Only providing subtitles; subtitles only transcribe the spoken language therefore some valuable auditory elements are not conveyed
- Instead: provide accurate closed captions to offer a more comprehensive understanding of the video
- Inserting media with Microsoft tools; the built in media players for Microsoft PowerPoint are inaccessible
- Instead: embed videos from accessible media players like YouTube
- Providing inaccurate or auto-generated captions and transcripts; errors in the text-alternative can impede the understandability of multimedia
- Instead: edit captions and transcripts before distributing your content
- Providing transcripts without timestamps; timestamps provide a roadmap to the transcript and related audio
- Instead: provide captions with timestamps at 15 second intervals for shorter videos. For longer videos, timestamps are required at least at the following events:
- 说话人发生重大变化
- 改变话题
- 幻灯片变化
- Instead: provide captions with timestamps at 15 second intervals for shorter videos. For longer videos, timestamps are required at least at the following events:
- Displaying visuals in a video with no alternative; visuals in videos need to be given proper support to be understood by students using screen readers
- Instead: explain visuals during recording or retroactively add audio description
