Video Content Type Welcome Page

Question

For most document sets, you can determine which fields show on the welcome page by going to Document Set settings - Welcome Page Columns, but the Welcome Page Columns section does not show on the OOB Video Content Type. How do I change which fields show
on the welcome page for a video?
Specifically, I want to be able to display a custom field and remove the owner field.

Hi,
According to your post, my understanding is that you got an error while creating custom document set content type.
The issue is that you set the Inherits=”FALSE” in the element. If you set the Inherits=”TRUE”, the content type would work.
Based on the article form MSDN:
If Inherits is TRUE, the child content type inherits all fields that are in the parent, including fields that users have added.
If Inherits is FALSE or absent and the parent content type is a built-in type, the child content type inherits only the fields that were in the parent content type when SharePoint Foundation was installed.
The child content type does not have any fields that users have added to the parent content type.
If Inherits is FALSE or absent and the parent content type was provisioned by a sandboxed solution, the child does not inherit any fields from the parent.
It means if you set the Inherits to true, we would lose all our customization there.
If we set Inherits="FALSE", which means you then have to remember to explicitly add into the definition all the stuff you should be inheriting, like the default Doc Set event receivers.
