Accessible Videos


Content editors must provide synchronized captions for all live multimedia containing audio e.g. audio-only broadcasts, web casts, videos, video conferences and Flash animations. When uploading a video, you must use a captioning services like those provided by YouTube or Vimeo. We recommend you manually enter captions, and then use the auto sync function versus using the auto captioning services provided on YouTube or Vimeo. Since our multimedia upload button allows for YouTube and Vimeo links only, we require you to have captioned your videos prior to uploading the link.

Our site does not currently permit direct audio and video uploads. Permitted file extensions include txt, pdf, doc, xls, ppt. If your department or college does not have a YouTube or Vimeo channel to host your video, you must provide UMC with the video file in mov, mp3 or mp4 format with an accompanying written transcript. It works best to send the video file via Box. We will publish the video to our official university YouTube channel as unlisted, caption your video via the transcript and provide you with a link to insert into the multimedia upload button within the editor. Videos provided to UMC remain unlisted within our official YouTube channel unless created, edited and published by the UMC video team or upon further discussion.


No page content should flash more than three times per second unless the flashes emit low contrast and do not contain much red. While our site does not currently incorporate flashing media, uploaded or embedded content from third-party services must comply with the W3 Standards for acceptable flash thresholds.

Timed content

Users need the option to turn off, adjust or extend the time limit of a page or element with timed content; real-time events need not meet this requirement. Users need the option to pause, stop or hide automatically moving, blinking, or scrolling content lasting longer than five seconds. Alternatively, content editors may upload moving, blinking or scrolling content less than five seconds. Users need the option to pause, stop, hide and manually control automatically updating content e.g. automatically redirecting or refreshing a page, a news ticker, AJAX updated field or notification alert.

Our site design does not currently use moving, blinking, or scrolling content. If content editors embed code or content from third-party services, they must use only those which comply with these time-based guidelines.

Audio control

A mechanism should be provided to stop, pause, mute, or adjust volume for audio that automatically plays on a page for more than 3 seconds.

Our site structure does not currently include auto-playing audio however, content editors who embed automatically-playing audio must seek training on how to do so with services that provide players to stop, pause mute and adjust volume controls. Vimeo and YouTube both provide this.
