A realtor would like to add a 1280x720 MP4 video ad placement to their new In-Stream Video campaign.To include this video format and resolution in their campaign, what step should they take?

To include a specific video format and resolution like 1280x720 MP4, the realtor needs to enable that exact option in the transcode list within Campaign Manager 360. This ensures that the video is transcoded into the necessary specifications for delivery. Submitting a new tag to publishers is incorrect because the ad serving setup is managed within Campaign Manager 360, not by publishers directly creating new tags for specific formats. Selecting any transcode with a video bitrate of 1500 kbps or higher is insufficient as it doesn't guarantee the correct resolution or format. Enabling every horizontal transcode option is unnecessary and inefficient, as it would create many unused transcodes, increasing processing time and storage without directly addressing the need for a specific format and resolution.
