Stream (on SharePoint) is moving away from the concept of a central video portal to make videos more integrated with other Microsoft 365 applications. This means the community will have opportunities to create news ways to share and display videos, including playlists and video galleries. 

SharePoint is rolling out an enhanced video gallery view that lets users create pages where they can display videos of their choice. This feature will be rolled out mid-July. We will provide instructions once they are available, and you can keep track of the feature development here: Microsoft has announced playlists and new Stream Web part.
