Now 3p is not a launcher of any sort. It's a safe poke with a deep stun on counter hit and in stun. Do this move twice and you'll get a static launch height (always the same) that will offer you a pp6pk (or a 3p, 6kk that might be more damage).
Yeah, a whole video with tons of moves and I'm supposed to pin-point the one you're talking about? Nope.
But moves like Ryu's 8P I call "pseudo-launchers." Not sure what name others have given them.
