The issue with in studio motion capture seems to steam from the poor directing, and the fact that it differs from real game adrenaline infused performance.
@3:02 mark "... and then Eldon will look at the data after it's been capture and he can clean it up. When he's done, he'll send the data off to the game team and they'll put it on the model ... " Not exactly sure what his definition of "clean it up" is.
@2:31 mark: One of the motion capture director does a QB drop back "bounce" in place. Very robotic scripted "bounce." This "bounce" is frequently seen in Madden's QB, but I have never really seen it in a real life game. This Madden bounce lacks a real purpose. I have included video highlights of both Drew Brees and Russell Wilson below. Take notice of their drop back bounces in the pocket.
@2:57 mark: Not sure why they would motion capture a slowed down version of a play action pass (hand off)
@3:24 mark: Not exactly sure what that is suppose to depict. Either a possible reception or an interception, but that particular "jump towards the ball" motion capture doesn't represent anything I have seen in a real life game. I think it's what's seen during a swat in Madden. It looks poorly scripted, and poorly executed by the motion capture artist.
Notice how the QB "bounce" in the pocket (e.g. Russell Wilson, Drew Brees) has real purpose unlike the Madden's motion captured or directed QB "bounce." Madden's QB "bounce" looks to be aesthetics only with no real purpose.
