A PC accessories retailer has decided to add a new 640x480 MP4 video ad placement to their In-stream Video campaign.In Campaign Manager 360, what step should they take to include this video format and resolution option in their campaign?

Analysis of Correct Answer(s) - In Campaign Manager 360, video creatives start with a single high-quality source file. This file is then transcoded into multiple smaller serving files of different resolutions and formats to accommodate various publisher requirements. To generate a specific version like a 640x480 MP4, you must explicitly enable that option in the creative's transcoding settings. By enabling the specific option in the transcode list, you instruct Campaign Manager 360 to create that particular serving file, making it available for assignment to placements.

Analysis of Incorrect Options - Take no further steps after uploading the video file: Uploading the source file is only the first step. Transcoding does not happen automatically for all possible formats; you must configure which serving files to create. - Enable all transcoding options in the list: This is inefficient and not a best practice. It creates numerous unnecessary files, which can slow down processing. You should only enable the specific formats needed for your campaign's placements. - Submit a new tag to publishers who'll serve the ad: Sending placement tags to publishers is a final step in the trafficking workflow. It occurs after the creative, including all its necessary serving files, has been fully set up within Campaign Manager 360.
