Video Ads (formerly in-stream video ads)

Important Notes: Optional Companion

YouTube is aware of ad delivery issues with some companion units (300x250s & 300x60s) due to the nature of how VAST is requested and rendered by the IMA SDK. As a result, companion banners may not always appear. Please note that the unit itself is not billed upon and not guaranteed. We are working to resolve these issues as soon as possible.
