You can assign multiple authors to your individual pieces of video content when editing the video details
How to Assign Multiple Authors to a Video
Simply scroll down to Organize and click the Authors drop-down menu to select the Authors you want to assign.
You can select up to 5 Authors for any one video.
Multiple Authors on the Catalog
When your audience clicks on a video that has multiple Authors assigned to it, they will be able to see all assigned Authors under the video title:
They will be brought to the Author's profile page if they click on an Author.
For videos tagged with multiple Authors, all Authors who have been tagged will be tracked in the video's views and watch time analytics.
This means that if three Authors are tagged on a video that gets 10 views and 5 hours of watch time, all three Authors will see their views and watch time hours increase by 10 and 5, respectively.
To view your Author analytics in the Admin Area, navigate to the left-hand menu and click Analytics > Content > Authors.
