Interesting, your result looks nice. This is where I get to with vdub:
Would be good to go if I somehow fixed the skylight.
Some ideas I'm thinking about
:
adding another gauge to desaturate overflows (turns something very bright into white)
adding 3-way thing with adjustable split points (it seems a fixed split is not enough)
producing alpha mask at some point and applying it to secondary filter (too much complexity begins)
What is the soft-clip you are talking about, is it a tweak in Channel Mixer? What it does?
Re: cineform does Resolve always export full range? I saw no obvious flag in SDK to realize full/limited range. Can you export this same frame as cineform?
