Checkpoint 2.4 - Audio and Video

Some users may not have particular programs and therefore need to know what format a file is prior to downloading it. Other people with disabilities may know that their assistive technology doesn't work with a particular technology and therefore will avoid downloads of that format.

People are sometimes searching for specific information and often it is not clear whether that information is available in a particular download file. Providing summary information ensures that users know what information is provided. When a proper text equivalent is provided, the summary description of the file is not required.

Requirement

Every video file needs to include the following information:

• File type
• File size
• Duration of video file
• Summary of content (if relevant)

Example
