Delta Key Artefacts

Hi,

I have been having this problem when using the Delta Keyer in Fusion.

Just to note as well, I created this edit in DaVinci Resolve 18 and it was doing the exact same thing even though I am now working in DaVinci Resolve 19.

For some reason when I've applied the Delta Keyer, there seems to be some little black artefacts floating around the subjects head when the video is played back. It happens as well after the video has been exported out.

When the frame, in DaVinci is static, the artefacts disappear.

Would anyone know what the cause of this issue could be?

Regards

Hey

You saw that only with the delta keyer ? In the first place I thought you wrote about noise, then when zoomed in, I saw those squares as well...
It won't help but it looks like GPU artifacts...

Change the rescaling filter in Resolve project settings, it is buggy and messes with semitransparent areas when filter has sharpening effect and Fu comp gets resized on timeline.
