32b add grain workflow

Postby Mr K on 09/30/2017, 2:23 pm

I'm working on some shots delivered in floating point EXR sequences.
I have degrained them using NeatVideo, done some cleanup and now need to add the grain back on.
Problem is both the Match Grain and Add Grain work only in 8bit and 16bit modes. In 32bit mode they could introduce colour value clipping.
Cannot use noise since grain must be matched more precisely.

Anybody know a plugin/method to add grain while respecting 32bit values?

Genarts sapphire, but not sure about 32bit support. I could test a bit later

Possibly bcc or nuke may have inherent 32bit grain support
