This sound is the Pokémon capture fanfare associated with catching a Pokémon in the main game series, with music credited here to Jun'ichi Masuda. The cue became widely recognizable through years of repeated use across Pokémon titles and gameplay videos online. It still shows up in edits because the meaning is instantly clear even without visuals: something was successfully collected, secured, or obtained. That simple success signal makes it useful far beyond Pokémon clips, especially in short gaming posts and reaction edits.
