Module 7: Checkpoint 6—Display size

Conformance: Mandatory


Video must display at a maximum size of 640 x 480 if the space is available.

Video must resize down from the maximum size when space is not available.

The source video must be compressed for 640 x 480.

Note: Fullscreen or 'faux fullscreen' (i.e: larger video in a floating layer or lightbox) modes may also be provided.

Benefits of conformance

  • Ensures universal access to online video content.
  • Compatibility with mobile devices.
  • Seamless integration with the CUE template.

Risks of non-conformance

  • User frustration and reverse channel migration.
