Re: Video ads. Views vs. Video Impressions 2:
As per Adwords notes:
Views: It displays the number of times your video ad was viewed by the user, within the selected campaign. A view occurs when a user watches your video. For TrueView video ads, the views on your video ad will also count toward your public YouTube viewcount.
In terms of Video impressions, it is categorized under 2 features namely Thumbnail and Video. As per Adwords reference, they are defined as :
Thumbnail: Thumbnail impressions are counted each time someone sees your video ad displayed with your video thumbnail. When your ad is displayed, the user must click on the ad to start the video playback.
Video: Video impressions are counted only for in-stream ads. In-stream is a format where your video ad begins playing without a user clicking to watch the ad.
