HD Video

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

All HD videos must be hosted by Beeswax as publishers that support HD do not allow tags currently. 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). 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 only. More information on Hulu’s requirements can be found here
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.
