Convert 6:19 Landscape Video to 9:16 Whatsapp status format

I have a single 6-minute-24-second video that was shot in 16:9. I need it re-framed to a true 9:16 aspect ratio that is compatible with WhatsApp Status—so no letter-boxing, pillar-boxing, oversized padding, or other quick fixes that leave black bars + Split video into 30 seconds clips...
