To say I'm a novice video editor would be generous. I'm tasked with a product demo that needs the classic "Million Points of Light" video effect.
The layout would be an empty world map surrounded by 6-10 human portraits. Each portrait would transform into (or generate) an animated glowing light that moves from the portrait to its respective region of the world and shrinks to a small point. Then millions of light points would bloom around the world to produce something similar to the classic Facebook map.

Any specific guidance on a workflow and tool set to best achieve this effect or something similar would be welcomed. Is this too advanced for laymen to put together from scratch in a day or so? I am familiar with Adobe Premiere and have access to After Effects.
