Cropping and duplicating
I was wondering how I would how I would be able to crop or track a high moving clip and double or even triple the part I want to add. this clip here is of the girl running, but I wanted to know I could have it at some point where I could clone just her running and even have some of them behind her layer-wise. like between her and the back ground so to speak. I tried thinking of clips to better explain what I'm thinking of, but nothing came to mind.
