If you can get the vid to work, start at 41 minutes. Looks like Roman style is what we usually see from the popes. It's not a handshake. It's approaching the other, clasping the upper arms or shoulders, and pressing cheek to cheek. Doesn't look any different from other masses I've seen celebrated by recent popes.
Is this what the lay people attending the Mass are doing or just clergy? It would take my connection much too long at 768kbps to download to check for myself.
