The Media Manager requires all content to be uploaded before publishing to ON24 Engagement Hubs, Target pages, or social media. It supports various formats like events, images, webpages, and AI-Generated content.

Content Formats

Your content must be uploaded to the Media Manager before it can be published to ON24 Engagement Hubs, ON24 Target pages, or social media.

Up to 50 items are displayed per page of the Media Manager. There are currently no limits to the number of pieces of content that can be stored within the Media Manager.

Content is sorted by date (most recent descending) by default.

Events	Any Webcast or Forum you run will automatically be added to your Media Manager Search for the events using the Content Type filter In addition, a video copy of the completed LIVE webinar (i.e. webcast video) will be sent directly to the Media Manager when the webinar is over. For Forum events or pre-recorded webinars (Simu-live or On-Demand Recordings), you will need to manually create a Single File Archive for a video to be visible in the Media Manager.

Using Content

Categorizing and Publishing Content

Once content has been uploaded to the Media Manager, it needs to be published to an Engagement Hub to be available for use in your Engagement Hubs and Target Content Experiences. You can choose which Engagement Hub category your content should be published to directly from the Media Manager.

Use the icons next to the content or in the Flyout Panel to publish to an Engagement Hub.

During the publish flow, simply select or deselect categories to keep your content organized from the start. This streamlines your workflow and ensures your hub remains structured.

Scheduling Content Unpublishing

You can schedule a specific date and time for content to be unpublished when publishing to the Engagement Hub through the Media Manager. This helps manage time-sensitive or compliance-driven content without manual follow-up.

The unpublish setting is off by default, meaning content will remain published unless a date/time is set
Available only in Media Manager, and set per content item
Applies only to the Engagement Hub (not to Target or Nurture Pages, which still require manual unpublishing)
Does not apply to social media channels
Analytics and reporting remain available after unpublishing
