Hi, this is my firs post so i hope i write in the right section as everything is yet new to me.
I am working on a project for school, using a green screen.
My problem is I want to have a live street as a background on the green screen, while 2 characters move very little in the video. At some point a third person enters the stage, but as a background person, and at the same time to have the background stop as "the time stops" and have an interaction between the 1st and 3rd persons all of them shall be on the green screen.
What is the complexity of this project, as i am still a beginner?
