Esxi running macos For selur

[Selur]

I used
clip = core.std.Levels(clip=clip, min_in=0, max_in=1020, min_out=160, max_out=880)
with a 10bit source, before I used a 8 bit source.
and the output looks fine too.
Ah using:
clip = core.std.Levels(clip=clip, min_in=160, max_in=1020, min_out=160, max_out=880)
I get the a greem output where there should none.

-> this looks like a bug in the filter or I messed value scaling
