Re: The effect is not only visual...
1991 Gulf War: BBC reporters on analogue satellite feeds, if noise then lots of 'snow' like a dodgy VHS tape. Reporter's face moved naturally like a human.
2003 Gulf War: Reporters on a digital satellite system. Any noise caused blocking, pixelation, and jerky inhuman movement.
tl;dr even a very fuzzy blurry moving image can look very human looking if the movement is appropriate.
