What ad formats are displayed through AdSense for video?

Right now, we'll be using two ad formats: an InVideo overlay ad and a text overlay ad.
• InVideo overlay ads are Flash-based and will be targeted to publishers' content based on the relevance of advertisers' campaigns to your content. Advertisers may choose to include a companion video ad which opens when a user clicks on the overlay, pausing the content and playing a video ad within the video player. InVideo ads will compete in the Google auction and are paid on a cost-per-thousand impressions basis.
• Text overlay ads are drawn from the campaigns of AdWords advertisers and may be contextually targeted to signals in your video and your site. These ads may also be placement-targeted to your site and appear within your video streams. When contextually targeted, text overlay ads are paid on a cost-per-click basis. When placement-targeted, they are paid on a cost-per-thousand impressions basis.
