In-Video: How to implement In-Video (VAST)

We introduced this format to offer publishers greater flexibility to show an ad at a specific moment during the video playback. You are able to configure different predefined parameters in 3 different sizes. 300x250, 468x60 & 728x90

Creating the ad zone

Step 1

First go to the “Sites & Zones” tab and click “New Zone

There is a drop down menu listing all your websites, select which one you want to place the in-stream ad zone.

Step 2

Click on the "Video" drop down menu and select "In-Video Banner (VAST) " ad click "NEXT"

Step 3

Your Site name will appear above the edit options, which you set in the previous steps.

Now you need to:

  • Name: personalise the ad zone name to suit your own needs (at least 5 characters long).

  • Category (default): this is automatically selected based on the category of the site you selected in the previous step.

  • Subcategory: Unless you need to restrict the advertising further, we recommend you leave this blank.

  • Format: Select from the dropdown between Rectangle, Banner or Leaderboard sizes

  • Vertical Alignment: - This gives you the option where to position the ad within the video. Choose between Top, Middle, or Bottom from the drop down menu.

  • Trigger type: Select between Pre-Roll (at the start of the video), Pause (when the video is paused), Post roll (at the end of the video), or custom.

  • Custom Trigger Delay: If you select "Custom" as your trigger, you can decide precisely when in the video stream to show the advert. Choose between setting seconds or a percentage of the video before the ad appears.

  • Show Ad: You also have the option to show the ad until the video ends, or the visitor closes it, or to hide the advert after a period of time.
