I upload aerial images and videos from drones to Instagram.

Now I have the idea that hundreds of people walk trough these landscapes from multiple directions to one single place in the video.
The total video, where I would deliver the footage, contains about 4-5 scenes with different camera angles. It would probably contain a long shot and 2-3 closer scenes.
Your task would be to generate the crowd rendering that fit to the terrain of the video and merge the video plus the crowd renderings.
