Of course anything is possible. I guess it depends on how much time and effort you want to put into this. And since this wasn’t a planned post production visual effect, you will most definitely have lumps to take. Mocha is great at tracking things like the flat side of a shirt.

P.S. Are we talking more than one or two 5 second shots? The connotation I get from your post is that the “video” you want to edit is substantial.
