What's the difference between types?

Video - it's a video that you upload manually on our server.

VAST wrapper with video - it's a VAST tag without player replacing.

VAST wrapper with VPAID - it's a VAST tag, which provides a framework for embedding in-stream video ads.

Motion banner - this is a new advertising format that allows you to interact with an audience that was previously available only to advertisers using the classic Pre-roll (a short commercial before watching the video). Motion banner is an animated banner that will be displayed before the video, without the ability to close it for a while (minimum skip time is 5 seconds or more). You can also add a brief description of the product, call-to-action, to this banner.

Also you can choose ad place (all is selected by default).

A Pre-roll ad is a video advertisement that automatically plays directly before a featured video, on both mobile and desktop.

Pre-roll is shown on the embedded video in the publisher's websites.

If a publisher uses a third-party video player on his website in which video ads are launched, this is called Embedded pre-roll.

Video Slider is a pop-up modal window in the lower right corner of the screen where the video is played.

Native Roll is a video player that appears among the content on the site, pushing it aside to play ads.
