I'm trying to use this method to give the object translation value in pixels. Assuming the vector blur data is in ndc space, I would think multiplying against the resolution would give you the desired result, but I don't find a correlation.
For example, I have an object moving 136 pixels in Y. The image is 1K square. The value returning is 0.511 (x1000 = 511)
Any ideas of what's missing, or is my logic completely off?
Thanks!
