Second story
What really happened is the first story—the raw material. Compressing it to a digestible text, film, musical, etc., creates the second story. The second story has to be invented—it is not simple "there". For simple, just-film-along material, developing the second story is (a) much and (b) different work than recording the first story. Templates for second stories help with (a) and (b). But might create repeatable, boring second stories. Extension: There might be a third story. And a fourth. Etc.
