Does Patty ever appear to walk in a way that human cannot?
I think any claims that the gait can't be replicated are exaggerated. It may be tedious to maintain for an extended duration, but not impossible.
Tube, I seem to recall you having a picture somewhere of you replicating the gait paired with a quote from Krantz saying it couldn't be duplicated. Could you post that?
She duck-steps with the right foot for some strides, but not all? And the left foot is never seen to duck-step?
At least to my eye, correct on both counts. As has been common with the PGF, someone else may see something very different. The PGF is the Rorschach inkblot of cryptozoology.
Does it seem that for most of the footage, she is not duck-walking with either foot?
There is only a portion of the film where a couple of full strides can be seen without any obstruction of the lower legs and feet. So, anyone would be hard-pressed to describe the gait outside of those particular frames.
Why would Steindorf invent a skeleton and animate it to appear that Patty is a duck-stepping contraption by design?
Maybe his equpiment/eyes are better than mine or he's got a better copy of these frames. I could easily be incorrect (wouldn't be the first time). However, I can also see the pitfall of accepting this finding on faith.
Are you suggesting that he invented the rotation--whether intentionally or not?
If this bizarre gait is so significant, why does Patty generally appear to walk like a human?
I think the significance of the gait has been overblown. It's possible for a human to do, albeit somewhat taxing.
How much did they pay Steindorf for this?
I don't know. Doug Hajicek was the producer, so he would know.
If his conclusion was that Patty walks like a guy in a costume and he went on to animate that - would they have still paid him?
Another question for Doug Hajicek. I suspect he would answer in the affirmative (although he also might be irritated at the question).
I'm sure Hajicek's e-mail could be tracked down. I don't know him, so I don't know if he would respond or not.
I can only imagine that some other analyst would look at the footage and not need to make an animated funky monkey gait/skeleton in order to graphically illustrate what might be going on there.
At the Willow Creek symposium, Hajicek mentioned that he had talked to at least one other company to do this work. He went with VisionRealm (Steindorf's company) due to price considerations. However, there are other companies that could analyze the film in a similar fashion. It would be interesting to see what they came up with given the same inputs. Unfortunately, it's not practical to independently replicate the animation (i.e. time, money, labor).
I hope that helps.
