In-Stream Video refers to video ads that play within a video player, typically before (pre-roll), during (mid-roll), or after (post-roll) video content. In-stream ads are commonly used on platforms like YouTube and provide high-impact ad experiences.

In-stream video ads offer advertisers the advantage of capturing user attention in a video-focused environment. By appearing within content, these ads achieve high engagement rates and are effective for brand awareness and recall.
