You want to set transcoding for your client’s in-stream video creatives in their campaign.In which Campaign Manager 360 hierarchy would you have the ability to set transcoding for in-stream video creatives?

Transcoding settings for in-stream video creatives are configured at the Placement level in Campaign Manager 360. This is because placements define where and how ads will appear on a publisher's site, including specific technical requirements like video formats and quality. Setting transcoding at the placement ensures that the video creative is delivered in the optimal format for that particular inventory. Packages are used for grouping placements for organizational or pricing purposes, but they don't contain transcoding settings. Creatives are the actual assets, but their transcoding is determined by the placement they're assigned to, not the creative itself. Ads link creatives to placements and define targeting, but the technical video processing is handled at the placement level.
