Last Friday I've downloaded the alley footage. I just had a brief look at it, but the track really sucks (Noting personal to the person who did the track).
If I just drop a box on frame 40, and match it with the garage with 2 doors on the right, on frame 170 it has moved ‘a number aka to the next neighbor’.
Of cource its a good reason / motivates to get in to PFtrack and do it your self, but I wonder what's the use of providing the tracking data if it's not usable at all?

Is there a official topic for this challenge?

I have to agree that they could have tracked objects on the other side of the alley as well. I wanted to jump into some effect tests but I have to fight with tracking/object placement as well.

One of my colleagues did lately a fxphd pftrack course, so I'm on it to. ;-).
Very decent learning material by the way, I already love PFtrack.

yeah i noticed some float going on in the hamster shot. Is there going to be a retrack? or am I going to have to actually open up syntheyes? ha
