can someone tell me how this works? I can seem to get anything that looks right?

looks like it is data is R and G with Blue at a solid 0.5.

I am assuming you are piping the pass into the the vector motion blur node. Try sticking a BC in between your pass and the blur node and set the brightness to be -0.5. Make sure you render the pass out in float, if you are having trouble viewing the pass in the view try toggling normalise.

Cheers,
Dave

That sounds like you need to subtract 0.5 from every channel (BrightnessContrast tool with brightness = -0.5) with the velocity pass being loaded as either float16 or float32.
