Interactive Interstitial

The Interactive Interstitial is a rich-media unit that runs with or in place of a video commercial on living room, desktop, and/or mobile. The interstitial enables greater interaction within the player space.

Available On

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.


Deliverables to Hulu
  • Product Images (if applicable)
  • Audio (background audio must be heard throughout entire unit)
  • Brand logo (Vector .AI or .EPS preferred, .PSD accepted)
  • Copy & calls-to-action (if applicable)
  • Third-party tags
  • Click-thru URLs
  • 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.
  • Assets may be site served by Hulu or thirty party served via VAST tags (see below).
  • 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 / Lean-forward

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).
