Though it's not identified as such, I think this is a clip from an old TV show called "You Were There", which purposted to re-enact historical moments. Or it's something like that. The man reading the news looks like young Walter Cronkheit, though I don't think he was associated with that program. Whatever. But TV didn't exist at the time the Original Dixieland Jazz Band was making their first recordings (the 1910s).
