dynamic loss in render and can't render gpu full memory

hello all

i am gonna try to be as clear as possible.

i have a project i have been working on.
my clips are 4k dci dnxhr 4444 12bit made from proresraw files. color space is rec2020 and gamma is panasonic vlog
i work under resolve 16, timeline set to 2.5k rcm set to rec709

i have multiple clips, few fusion and coumpound clips too.
i have done my editing my grading, everything is ready to render.
most of my clips have a first node for noise reduction that i do using neat video 4

when i want to render my timeline i quickly have the gpu memory full problem. actually resolve tells me memory is full before i even try to render.

i tried to render to h264, h265 and dnxhr, always the same problem.

so what i tried to do is to export some clips, mostly fusion and coumpound clips using dnxhr 4444 12bit so i can replace clips using nr in my timeline with "baked" clips.

problem is that when i import those clips i notice some difference in contrat and latitude, the "baked" clips are flatter, less contrast and lower highlights. there is a difference in scopes.
i have less dynamic

when rendering i keep colorspace tag and gamma tag as "same as project", i also tried to change these to rec2020 but have worst issues with colors.



thanks

oh my this got lost in the list thanks to dvr17.
bringing it up

Check for "Full range" vs. "Video range".

did both, same result
