Put this clip first in the edit, over your opening card, then bring in your main footage straight after it ends. For a twist reveal later in the same video, follow the opening with the dun dun dun sound before the reveal shot.

This is the KOG Studio logo sound, a 5.9-second sting made for a studio ident at the start of a presentation. It feels grand, confident and a little theatrical, like something important is about to be unveiled. That mock-serious energy makes even a small homemade clip feel like it has been officially introduced and produced.
