I have done a test here using a video from

(direct link to
https://drive.google.com/open?id=1jcSp9JZR8eFKq9jTXNLbG5nFIjWhD8YJ ).
It is a 4k video H.265-10bit@25fps.
I used F_log3d and Histogram Bezier plugins (four points in Polynominal
mode on two keyframes) for the clips.
Because my Notebook is very old I must use Proxy. Rendering to H.264 and
H.265 but NEVER _nvenc (I can not) with Proxy enabled, to save time and
to see the output, and then the Final Render.
Here it seems all good. I think that the problem might be _nvenc.
All (almost) my Settings for that below (I don't know if it can help):
