Out-stream video refers to a type of online video advertisement that is displayed outside of traditional video players, such as within articles or on social media feeds. Unlike pre-roll or mid-roll ads, out-stream videos do not interrupt the user’s viewing experience and are often autoplayed with the sound off. This format allows for greater flexibility and creativity in advertising, as well as the potential for higher engagement and viewability rates. However, it also raises concerns about user experience and the potential for ad fraud. Overall, out-stream video has become a popular and effective way for brands to reach their target audience in a non-intrusive manner.
