Where is Twixtor Shake Documentation?

Hi, I'm having a tough time trying to use motion vectors in Twixtor Shake. I can't seem to find the manual (which is supposed to appear after install - but I'm not going to install again just to find it.)

Here's what I'm trying to do:

I've got a 3D scene rendered out. It's 30p. I need it to be 29.97i (or 60i, I suppose.) So I've taken it into Twixtor in Shake and set the speed to 50 percent. I then take this into FCP and change the speed to 200 percent with Frame Blending on. This is a method suggested by Marco Solorio here on the Cow.

This is working well aside from the motion artifacts I'm getting from Twixtor. So I thought I'd just bring in the motion vectors as these are easy to render. But I'm not sure how to format them properly and the Shake tutorial scene is not that easy to reverse-engineer.

Are there tricks to using motion vectors here?

Thanks,

Will
