Sorry, I'm just not getting this

Thanks for the help, guys. But I'm still a little lost. I'll try to break down my question:

I've rendered a scene out from C4D. It's several flat objects moving over a static background. I want to run this shot at 50 percent so that later I can speed it up and generate an interlaced file.

Please let me know if I understand this correctly:

I should render out one pass of motion vectors from C4D (I'm using R11.5)

This should only include the moving objects. The static objects should not be included in the vector pass.

Twixtor will then create its own alpha based on the vector pass(?) Or do I need to import a matte for this?

I also need to determine whether C4D renders out vectors looking forwards (next frame) or backwards (previous frame) (?)

And finally figure out whether these are in positive or negative spaces in relation to Twixtor's setup.

I only need to fill in one of Twixtor's vector inputs?

Thanks for your help,

W
