Is this version newer than x265-3.2.1+1?

Yes it is, this is compiled from the default branch and not the stable one.

The grain generation is often done in wrong ways that make it much harder to encode than real world grain. I especially see this in 4K and HDR, where grain gets rendered at the pixel level with SDR code values and so comes out way too bright and too fine-grained. I've seen synthetic film grain that made content impossible to encode at even vaguely acceptable quality at 40 Mbps.

We're also seeing silly amounts of film grain in restored rescans of movies. It isn't creative intent to preserve all kinds of noise that wouldn't have been visible on the perf screens and foot lamberts that the creatives actually approved the content on.

I hear you on the remastering, Ben.

Home Alone is an astounding example of this.

Also maybe try --hrd-concat if you are using HRD?

Watch the 4k77 UHD release of Star Wars if you want to see overdone grain. MCTD is calling its name when I build my new Zen 2 system in the next month or two.

Something definitely looked off with Home Alone. The pitch of the grain was both far too fine and too bright; it didn't gel at all with the image.

I must say though, I like the way the UHD release of Predator looks and it's pretty damn grainy. It looks right to me. Was shaky film stock from the outset IIRC.
