Your client wants to run their sneaker campaign across three different sports publishers, each with different video creative specifications. One accepts 300x250-only companion ads, one requires VAST and vPaid tags, and the third hasn't sent specifications.How should you traffic this campaign?

To efficiently manage varying technical requirements across multiple publishers, you should use the Publisher Spec library to effectively transcode videos because this centralized database within Campaign Manager 360 contains the pre-defined creative and technical standards for thousands of global sites. Instead of waiting for manual specification sheets or attempting to use a single placement for all, the Publisher Spec library allows you to select each specific sports publisher and automatically apply their required video transcodes, VAST/VPAID versions, and companion ad dimensions (like the 300x250 requirement) during the setup process. This ensures that the ad server generates the precise file renditions and tag types needed for each unique environment, guaranteeing compatibility and preventing delivery errors even before the third publisher provides their individual documentation.
