Well as the target audience you're alwas ****ed!

That's why for example in news broadcasts the host often says that the interview was pre-recorded. Or when we see politians making a statement with the Reichtag in the background: mostly they are in a windowless studio in front of a green-/bluebox.
In the example picture from the article, the one with the desktop, you can see that the background is rather plain, this is an easy manipulation. I would really want to see a moving image with a background that is also non-static, then I would be really amazed. But anyway, I believe that software doing this manipulation on their own does a rather quick and dirty job, with the right tools you can see that there is something missing or copied in - again I am not talking about the audience.
I am manipulating (editing) moving pictures of puking people right now. I love my job, especially when I drank last night
