Stream Classic inventory report - how does the report determine container name for orphaned videos?

I'm sorry I don't know the "logic" behind the distribution of orphans into their respective containers, but am seeing a similar kind of distribution where there's about 100-300 videos per container, then a couple are over that.

In our organization, most of this orphaned content is coming from people who have left the organization, or from M365 groups where the group was deleted. For the first scenario, there's really no one left to speak to the need for the contents, and we don't have the bandwidth to go chasing down managers of every termed worker who may have ever uploaded a video to classic. For the second scenario, it's possible to figure out what group it was connected to by way of the "Owners" column which offers an email address for the M365 group it was posted into.

But since we're talking about people who left the company, and about groups that have been deleted, it's our plan to put all the Orphaned content into site collection(s) that are restricted to admins only. If someone is looking for content, we can find it for them and move it to a destination they want. That approach may not work for everybody, but we are figuring the important thing is to "rescue" the data out of classic before it goes away. Getting it migrated to anywhere on SharePoint accomplishes that, and getting content claimed and distributed is secondary.
