The initial "Bref WC Karaoke" title card with a dynamic visual effect.

The ad opens with a title card for Bref WC Karaoke. It then transitions through several modern bathroom settings, each featuring a Bref toilet cleaner product. The visuals are sleek and dynamic, with close-ups of the toilet bowl and the product in action, showing cleaning bubbles and water flow. The pacing is quick, interspersing product shots with lifestyle imagery of clean bathrooms. The final scenes focus on the Bref Auto Activ product packaging and its cleaning mechanism.
