Accessibility & usability barriers 

Kaltura MediaSpace

The following are accessibility barriers that may be experienced by the end-user in Kaltura MediaSpace while viewing and navigating videos.

People who are blind or low vision and navigating via screen reader may have difficulty

The following barriers exist which will impact users who are blind or low vision and are navigating via screen reader on Kaltura MediaSpace.


People who are colorblind or have low vision may have difficulty

Some text in MediaSpace fails color contrast accessibility which may pose a barrier to people who are colorblind or have low vision. Some labels including video descriptions, “like” counts, and “play” counts may be difficult for some users to read. 

Additionally, the active transcript widget contains some color contrast accessibility barriers including the “Hide transcript” button, which is too light and hard to read. Also, the highlight color created when the user highlights transcript text is too light to read at times.


Kaltura MediaSpace (administrative experience)

The following are barriers which may be experienced by the user when uploading and managing video content.

Keyboard accessibility barriers may impact people who are blind or have motor disabilities

The “publish” button in the MediaSpace video authoring experience is not reachable via keyboard. To publish, the button can alternatively be reached by clicking on the “Actions” menu and finding “Publish” in the “Actions” dropdown via keyboard.

The “My Media” button is not reachable via keyboard. The button can alternatively be reached by navigating through the “Related Media” dropdown via keyboard.

Additionally, when the user is uploading captions, they see a pop-up appear asking for file, language, and more information about captioning appears. The user is not able to select options in the pop-up list for “language” via keyboard. Options can be alternatively selected if they manually type their options in order to get results. This required navigation is not intuitive and may not be discoverable for some users.


Kaltura Capture

People who are colorblind or low vision may have difficulty

Some users may have difficulty with the “suggest” and “suggest a new document” buttons at the bottom of the page due to low color contrast accessibility causing the labels to be hard to read.

People who are blind or low vision and navigating via screen reader may have difficulty

Some form inputs in Capture are missing the required HTML attribute which allows users navigating via a screen reader to know which fields are required.
