Alpha Channel inverted suddenly C4D

Ok I have that frame alphaing now. I simply increase the smoothness of the camera path from 5 down to 2.
Also of note (and where the hiccup was) you have a broken handle on the spline as it turns upward. you can fix that by selecting that point on the spline and choosing mesh/spline/softinterpolation .Then you can adjust it to be the angle to want and you will get a smooth transition from horizontal to your upward curve.
