The Interactive Advertising Bureau this week released Digital Video Ad Format Guidelines and Best Practices, including a slew of definitions for the various formats related to linear video ads, non-linear video ads and companion ads.

Of the many guidelines set by the IAB, it believes that overlay ads should run between 5-to-15 seconds, and while linear video can be inserted as pre-roll, mid-roll or post-roll, it should not exceed 30 seconds.

Since its guidelines were last issued in 2005, IAB CEO Randall Rothenberg said broadband video has moved well beyond the experimental phase. Today, new specifications are needed to help improve ad located in, on, and around Web video.
