Video Interstitial Split

Our largest format with an integrated video for maximum impact. The initial Video Interstitial Split ad space is divided into dynamically animated images and a static image that is clickable. Upon clicking on the video feature, it will run full screen – either portrait or landscape mode.

A clickable end banner is shown in the whole Video Interstitial Split ad space once the video stops playing, leading to an URL of choice.

If the user does not interact, the ad is automatically closed after 5 seconds
