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 | Bitrate | When to use |
HD Variable Bitrate | 400-20,000 kbps | Used for OTT/CTV activity (excluding Hulu and Peacock). This offers the widest range of supported bit rates which will increase creative match rates against incoming bid requests. |
HD Constant 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 kbps | Used for buying Peacock Inventory. Please reach out to your Account Manager to enable this transcoding option. |
Default (non-HD) | 400-600 kbps | Used for non-OTT/CTV activity |
*Please reach out to your account manager if you'd like to change the default transcoding option in the UI from ‘Default non-HD' to a HD option.
