The main thing that separates in-banner videos from other types of ads is that theyre not played in a video player. Basically, an in-banner video is a creative thats played in a standard banner placement. This means that it can be placed in banners of standard sizes, including 728?90, 160?600 and 300?250. As of 2017, in-banner videos are not frequently used by advertisers, although they definitely have the potential. In fact, theyve proved their worth in YouTube advertising, where they are commonly used on the homepage. That is why its expected that in-banner videos will become a regular advertisement type in the years to come.
