There is known Cross Hatching problem described in this thread viewtopic.php?f=2&t=51936&start=400
As you may know it can be fixed by shifting XY position to 0.5px. https://ursa-mini-fpn-grid-pattern-nois ... 18/fix-46k

it seems in Resolve 15 beta5 (tested non studio) it don't works as it should. It produces artifact at the edges. It is also visible at the rendered images. (see full sized images)

This is still don't fixed n Resolve 15.1.1
Dear developers please take attention to this problem! It worked well in Resolve 14 but you destroy things in Resolve 15 and still don't fix it.

Resize mode "Sharper" in Settings:
Edit Page XY 0.5 px transform produce = 1 pixel black frame edge on rendered image
Color Page Node sizing Pan/Tilt 0.5 px node transform = 1 pixel black frame edge on rendered image
Color Page Input sizing Pan/Tilt 0.5 px node transform = 1 pixel black frame edge on rendered image

Resize mode "Bicubic" in Settings:
Color Page Node sizing Pan/Tilt 0.5 px node transform = 1 pixel black frame edge
Color Page Input sizing Pan/Tilt 0.5 px node transform = NO pixel black edge.
Edit Page XY 0.5 px transform = NO pixel black edge.

But If you essentially select "Force sizing to highest quality" in render settings there is always 1 pixel black frame edge on rendered image with ANY previous settings.

BTW, don't you thinking about some kind of dedicated OFX plugin or some kind of setting button in RAW tab to fix Cross Hatching? This can make workflow way simpler.

P.S. There is a huge thread about this problem, Cross Hatching Wont Go Away viewtopic.php?f=2&t=51936 Setting Pan/Tilt 0.5 px is the ONLY way to fix it yet.

Problem still NOT fixed in Resolve 16 b6 :cry:

Currently the only way to avoid side pixel edge is:
- set clip attributes to to super scale 2x
- set clip Input sizing or Edit sizing Pan/Tilt to 0.5px

Hey Dmitry, Do you know if there is a download file anywhere for Camera settings: RAW, resolution 1920 x 1080?

Not sure if i understand what download are you talking about? Is it about That thumblr post? It just contains preset with two nodes: One node with Node Pan/Tilt position 0.5px. And another node with Pan/Tilt position -0.5px. I post that link just to show that Cross Hatching fix, exists and that i am not the only one who cares about it.

It is way simpler to add node manually than download those presets baked to different project resolutions.

Things became even more confused when multiple are settings combined:

Project Resize Filter Sharp + Clip Attributes SuperScale + Input sizing Pan/Tilt 0.5px = No Pixel line Edge
Project Resize Filter Sharp + Input sizing Pan/Tilt 0.5px = Pixel line Edge

Project Resize Filter Smooth or Bicubic + Clip Attributes SuperScale + Input sizing Pan/Tilt 0.5px = Pixel line Edge
Project Resize Filter Smooth or Bicubic + Input sizing Pan/Tilt 0.5px = No Pixel line Edge
