Multimedia

When creating multimedia content, it is important to include accessibility considerations in planning, scripting, storyboarding, recording, and producing audio and video (W3C, 2023). Adding accessibility best practices into your creation process helps to ensure the end result will be usable by people with disabilities.

Learn more about common accessibility barriers in producing audio and video content; such as adequately describing visual information for people who cannot see, requiring sight to understand video content and making text in the video hard to see due to low contrast between text and background colors.

According to WCAG success criterion 1.2.2, all recorded videos need accurate, synchronized captions to meet the baseline of accessibility requirements. Content authors and administrators are responsible for ensuring that all videos made publicly available on the Rice website include accurate closed captions. This also includes videos that are shared, but not necessarily created or owned by Rice content authors and administrators. Videos that are created for teaching and learning and are not shared publicly are categorized as “academic videos.” Learning Environments and OIT support two main platforms for creating and sharing academic videos in your Canvas courses.

Video Platforms at Rice

There are a variety of video platforms for recording, uploading and sharing video. Some platforms include automatic speech recognition (ASR) captions for uploaded videos, though the accuracy of these captions fall below the threshold of accessibility and manual editing for spelling, punctuation etc is required.

Zoom Cloud Recordings

Learning Environments fully support Zoom. In addition to live video meetings and webinars, you can use Zoom to create short lecture videos and demonstrations with screen and audio-sharing. When you record your Zoom meeting to the cloud, the recording will include synchronized closed captions and an interactive transcript.

Note that local recordings will not result in captioned videos; therefore, we strongly recommend that recordings be done through the cloud.

Zoom cloud recording ASR captions will require editing after production. Learn how to use the Zoom Caption Editor.

Zoom cloud recordings are not permanent. Learn more about Rice's Zoom Retention Policy.

To get started, upload new media in the My Media area of your Canvas course.
It will take some time for the video and automatic transcription captions to finish processing.

All videos uploaded to your Kaltura 'My Media' will receive automatic closed captions and transcripts.
Automatic captions are only roughly 70% to &5% accurate.
To make captions truly accessible, the accuracy should be closer to 99%.

Use the Kaltura Captions Editor to improve the accuracy of automatic captions.
Note that automatic captions are currently limited to English and Spanish.

YouTube is a popular platform for sharing public videos. Learning Environments does not provide support for YouTube, so use it at your own discretion. Learning Environments recommends using Kaltura for all academic videos.

Videos uploaded to YouTube will receive ASR captions, but they do not include proper capitalization and punctuation, so they will require some cleaning. Learn more about YouTube Captions.

Vimeo does not include automatic speech recognition captions, or a captions editor. We do not recommend using Vimeo without first having a detailed process for creating and uploading your own caption files in .SRT format.

If you decide to use Vimeo, see the Access @ Rice blog for our recommendation about creating and editing ASR captions in YouTube.
