Deoldify Vapoursynth filter

Thank you Selur, the cropping out the black border works really well.  There was very little cropping but the difference is significant.
The reason I wanted to reverse Retinex is these blocks that are formed. See attached pics.  Any suggestions how to reduce that?  I thought restoring the video to its original darkness would do the trick.   Perhaps there is a dithering method to apply here, if such a tool exist.
