Some additional tests:
1. using Nicolas material "04.yuv" with -m24,24,24 -t24,24,24
-M24,24,24. Result: OK, no tint (at least no other than that
already in the frames - can see this on the "white" window
decoration...).
2. using Nicolas material "04.yuv" with -m6,24,24 -t12,24,24
-M3,24,24. Result: OK, no tint.
3. using my neutral gray test-chart with Nicolas parameters (2).
Result: OK, no tint.
I personaly think, now, the tint is introduced elsewere in the chain
(which could be non-trivial to find out), possibly it's caused by the
lenght of the filter-chain or possibly it is *in* the sequence already
and quite well masked by noise (I had that one with a *red* shift for
one clip recorded in a rather dark environment. And after a long time of
testing, I found the source to be the fault...). Nicolas, I will (as my
time allows) go through your chain an check but I don not believe that
it could be the denoiser, anymore... this must be something different...
