The initial green line graphic forming the word 'CHOP'.

The video opens with a blue background and a simple green line graphic that resembles a heartbeat. The graphic then forms the word 'CHOP' with a green line running through it, followed by the full logo 'CHOP' with the tagline 'Análisis clínicos y estudios especializados'. The scene transitions to a doctor in a white coat showing a tablet to a female patient in a doctor's office. The doctor points to the tablet screen. Text overlays appear, and a large pink circle with '30% de descuento en estudios' appears. The logo and tagline are visible at the bottom.
