What could be the cause of this ?
no matter what preset I use in handbrake, this checkerboard effect happens.
i'm trying to encode x265 10 bit files to x265 10 bit files
thank you and sorry for my english

What does your immediate source look like ? Is pattern there?
Is this screenshot 1:1 , or zoomed ? (NM, the title says "zoomed")
How did you take screenshot ?
Might be a dithering pattern. For example from 8bit original souce to 10bit your source -
thanks for answering.
the source looks perfect, the pattern is not there
both screenshots were done using MPC-BE save image as png (madvr)

I vaguely recall reading somewhere handbrake doesn't do a clean 10bit pathway. It's actually 8bit pipeline. That could explain the dithering patterns
edit:
- High bit depth encoding support via external shared libraries (video pipeline is still 8-bit 4:2:0) -
That makes sense. I don't have this issue with Staxrip.
I love handbrake's GUI more but I guess I'll have to forget about it.
