Overview

HD Video Creatives are a requirement for some publishers that want to maintain a high-fidelity experience for their viewers. These requirements are enforced at the publisher level rather than by the exchange, and are most common among OTT/CTV publishers. 

Video Transcoding

To enable transcoding of HD creatives, select one of the below options from the dropdown when you upload a new asset.  

Transcoding Option

When to use

HD Variable Bitrate

20,000 kbps

Used for buying Hulu inventory. More information on Hulu’s requirements can be found in Hulu Buyer's Guide.

HD Constant Bitrate (MP4 Only)20,000 kbpsUsed for buying Peacock Inventory. Please reach out to your Account Manager to enable this transcoding option.  

Default (non-HD)
