Exactly. And many people will readily say that "common sense" isn't very common.

Maybe not, but you _do_ need to have even the vaguest idea of mass/energy 
equilibriums (even without knowing that term). Many people have very little 
idea what goes on in a video codec, let alone why one might be faster than 
another on some hardware or why some streams are more compressible than others.

Instead of saying "this is obvious! why are you asking??" you could just 
patiently explain the answer. Or not answer at all and leave it to someone else.
