In-video Overlay Ads
How YouTube In-video Overlay Ads Work
YouTube In-video overlay ads are 480x70 image ads that appear overlaid on the bottom of the YouTube video player on the YouTube watch pages. The overlay ad appears when user initiates video play. You can optionally include a 300x250 companion display ad. See screenshot below.
Note that In-video Overlays are only available for reservation sponsorship campaigns. On auction, you can set up Image Ads to appear as an overlay on the YouTube watch pages. See more information on Image Overlay ads here.

Important Note: 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.
