I have the t3i.
What is "clean"? It looks fine to me but you do run into those purists and for them I can't help.
But I'd ask another question such as if the camera autoshuts down after so many minutes. I won't test that for you since it's not the t4i but folk that are trying to use such as a video camera like you see in studios often forget that most consumer gear will not stay on.
