The video tutorial explains the concept of visitation in programming, focusing on the use of the visit function and visitors to interact with variant members. It covers creating visitors to read and modify variant members, using lambda expressions as visitors, and employing type traits for operations based on member types. The tutorial concludes with finalizing the code and running it to demonstrate the changes made to variant members.
