Facebook in-stream video advertising lets you deliver mid-roll video ads on Facebook and Audience Network. These mid-roll video ads are shown to people who are watching video content from publishing partners on Facebook.

Facebook in-stream video ads are included in automatic placements. To opt out of automatic placement and delivery, or to select in-stream placement and delivery only, edit your placements. Learn more about choosing placements.

In-stream video ad host video eligibility

• Brand safety. Publishing partners work closely with Facebook's media partnerships team to ensure that their host video content is high quality. (Managed accounts can download a publisher list showing Pages that host in-stream ads.)
• Length of host videos. Only videos that are three minutes or longer from our publishing partners are eligible to host in-stream video ads.

In-stream video ad delivery

• Ad breaks. Publishing partners decide when ad breaks occur, but the first available ad break for in-stream video is at the 1-minute mark.
• Ad delivery. To create a good experience for people seeing video ads, we manage ad loads. For instance, not every ad break is filled. To optimise delivery, ad delivery within ad breaks is always being tested according to particular videos and individual viewers.
