After creating your campaign, you will be redirected to the creative page, where you will be able to select the Media Type. Select: Native Ad.
First you need to select the Video Player Size(s) that you want. After selecting your video, your AdTag and Landing page are automatically generated.
Linear ads are video ads that appear before (pre-roll), after (post-roll), or during a break in the video content (mid-roll).
Non-linear ads are display or video ads that appear during video content playback, without disrupting playback.
If your video is not skipable, the minimal and maximal duration should be the same. If they are, the minimal duration is the time that goes before the user can skip the video.
