Place it at the very start of your edit as the opening title, then follow it with A Few Moments Later to jump into the main scene, and finish the premiere moment with Clapping once the reveal lands.
About this sound
This four-second clip is a mock studio logo sting built around a long swelling boom that rolls on before breaking into a short giggling laugh. It feels stately at first and then suddenly playful, as if a serious cinema opening cannot keep a straight face, giving it a knowing, slightly absurd charm for a film opening.
