Put it first in the edit as the opening beat, then follow it with a cheer once everyone is in frame, and add a baby laugh after the opening line before the main clip starts.
이 사운드에 대해
This clip is a single drawn-out vocal greeting lasting just over a second, with one voice stretching the word hi into a long, friendly call. It feels warm and welcoming, like someone genuinely pleased to see you, and it lands as playful rather than formal, making a simple hello feel personal and upbeat.
