Place this greeting at the very start of a clip or right after a cut to a new scene, as the opening beat before the main action. Follow it with a reaction sound once the other person responds, and keep it early rather than burying it mid montage.

This is a short voice clip of French rapper Orelsan delivering the everyday greeting bonjour ça va in a flat, matter-of-fact tone. At just under five seconds it lands as dryly funny and slightly awkward, like a too-polite hello dropped into a conversation that did not need one, which is why it works as a deadpan reaction.
