0–3s

“Um... eu... desculpa.”

Split-screen stammer. Vertical 9:16 UGC clip, 3 seconds, one continuous handheld take unless timecodes say cut.

0–3s: Split-screen MCU / MCU. Top: stammering. Bottom: fluent and laughing. Labels 'Day 1' and 'Day 60' added in edit.
Vertical 9:16 split-screen, top and bottom halves, both static selfie framing at the same bedroom desk at dusk with a warm desk lamp and a corkboard with a printed map behind. Top half: a 27-year-old Korean man with short black hair and a soft fringe, round silver glasses, olive bomber over a grey hoodie and white wireless earbuds stares at his phone, stammering, rubbing his forehead. Bottom half: the same man in the same outfit talks easily and laughs into the phone. Natural skin texture, shot on iPhone front camera, unpolished home lighting, vertical 9:16.
Dialogue (Boyfriend learning his partner's family language, late 20s): "Um... eu... desculpa."
No subtitles. No on-screen text. No logos. Natural voice, no background music.

Why it works

Before/after in an app ad usually needs a screen; here the 'after' is audible, which is far more believable for speaking. The split-screen gives sound-off viewers the contrast instantly, and the proof plays both recordings so the viewer judges for themselves.

Hook variants to A/B test

  • “Listen to day one. Now listen to day sixty.”
  • “I recorded myself every day for two months.”
  • “Same guy. Same desk. Very different Portuguese.”
