Interactive Interstitial


The Interactive Interstitial is a rich-media flash unit that runs with or in place of a video commercial. The interstitial enables greater interaction within the player space.

  • Can include static imagery and messaging, or full rich media including animation or flash video.
  • Playback does not extend beyond the player window, no expandable units allowed.
  • Can include multiple link events, form fields, etc. that can be tracked via click command. Form field data will either be captured by Hulu or can use a 1 × 1.
  • Must include audio throughout the unit.
  • Heavy or exclusive use of vector assets is highly recommended to ensure smooth scaling within the player window as users toggle to full screen mode.
  • All assets must be site served by Hulu, no third party serving allowed (of source or functional calls).
  • We recommend that core branding or actionable elements do not extend into the top 38 pixels or bottom 70 pixels of the unit as those will be covered by the ad countdown timer and player controls on rollover. These areas may not be fully visible or available for click action, but should still be part of the full 1184 × 666 design.

- Lean-back experience: Will time out if the user does not interact with the unit. Will include the standard Hulu ad countdown bar in the top 35 pixels of the player window.
Click through to another site from within the Interstitial will open a new browser window.

- Lean-forward experience: If interaction options are available within the unit, a “Return to Video” option will appear if a user decides to click somewhere within the unit allowing them to return to the content experience whenever they are ready (this prevents a user from voluntarily becoming engaged and the user getting ‘kicked out’ at the end of the experience).

Build Timeline

Production lead-time is typically 6 weeks from the receipt of the final assets. However, each Interstitial has a unique production timeline based off project's scope and scale.

General Notes

• Client provided, or Hulu Creative Services can create these units for the client based on client direction and source assets.
• If client is providing, final FLAs must be submitted along with all class and font files. Hulu will provide a sample template which includes actionscript required for communication between the ad and player. All elements and all desired tracking must be baked into the unit prior to submission.
• If Hulu is creating, source assets should include vector assets (.ai or .eps) to ensure scalability, as well as specific fonts required and any clicktags or tracking required. All assets are subject to Hulu approval to ensure an optimal user experience.
• The timeline and associated costs for advanced Product Interstitials will be determined on a case-by-case basis and must be approved by Hulu Creative Services.
• Unit can be targeted at a national or local level.
