Is motion blur automatically selected when supersampling is selected in the video bus?

((No, they are 2 very differnt entities, the only relationship they share is the means in which they are utlilised.. theyre not actual effects per se.. even though motion blur (IMO) should be a filter... its nto treated as such))

Can get motion blur selected by itself, but when supersampling is selected motion blur is checked, seemingly by default.
((U can turn these envelopes on and off as u need to.. jsut right click the grey track header and select teh appropriate envelope to reveal the one u want to use))

That the way it's supposed to be or is there a way to over ride the blur application?

((Blur is not automatic.. be sure its UNCHECKED when u do the above procedure.. ))
