I figured out, that real pink banners were placed on the objects and on the streets of the city. Now, i am trying to find out, how this could be done with after effects. I did not find out, what technique this could be at all. I am also interested in another thing, that should be similiar. There are a lot of videos showing how to Make "Growing vines in After Effects". Now i am really interested, how to place these vines for example as a realistic layer on a street or an object in a movie that i filmed before. Could you maybe help me out with this question?
So my basic question would be, if anyone could tell me, how i could achieve this, where to get to know more about this. I already looked for topics like "Tracking 2d text in videos", "tracking objects/ drawings into video content" etc.
