Microsoft Filmstrip


The IAB Filmstrip Ad allows for creative story-telling through a series of three to five 300x600 panels. The first panel is loaded on initial visit.  On page load, max 15 seconds of animation commences within the 300x600.  The user can move between the panels in the following ways: 

  • Direct Interaction (On Click) – There are predefined areas at the top and bottom of the panels that allow the user to click to move to the next panel.  It is recommended that there be a clear call to action message to the user in these spaces. 
  • Scroll (On Mouse or Browser Scroll) – As the user scrolls down the web page the IAB Filmstrip will automatically move to the next panel of the creative if they have not interacted with it previously.  To ensure a clean understandable user interaction, the IAB Filmstrip only scrolls one panel per page. 
  • Sequencing (Repeat Visits) – Any return visits to the site will auto scroll the IAB Filmstrip to the next sequential frame.
