Effect does not go all the way to the edge

So I am trying to ad the censor effect, but for some reasons there is a clear boarder along the side edges where it does not work. Anyone have any idea what is happening here?

So the aspect ratio of this project is 2:1, so I tried to make a whole new project with standard aspect ratio, if that hade to do with anything, but the same thing happened.

What's the media?

What do you mean?

You have video files or stills images in your project? What are the specifications of the media?

It is video files shot with a Sony A7sIII

The camera shoots quite a number of different formats, so not certain I have what you have. The media I have from that camera in a 4K project with the current OS and FCP doesnt show that problem.

@Javrri
Perhaps include project pixel dimensions vs clip pixel dimensions so we know how they might differ.
Two things to think about:
Is the clip set to Fit, Fill, or, None? Perhaps that's having an impact even if it shouldn't.
Does putting the clip in a Compound Clip and then adding the censor effect then work to the edges?

I have noticed this issue in some fx with 4k footage in a 1080 project and Spacial Conform set to Fit. Setting SC to fill corrected the issue.

Probably it’s the "pixel block" size.
Unfortunately I’m not at a computer and it’s difficult to describe without pictures.
The pixelate effect takes a region of x by x pixels, calculates the average color and fills the region with that color.
If the region needed for calculations is smaller the process will be skipped.
You can create a compound clip which is a bit bigger, but then the effect will take the "black" outside into the calculations.
You also could mirror the clip at all edges and sides - but I‘ve no idea about performance.

Since my project is 4k 2:1 I change fit to fill under spacial conform. I have tried both and the problem remains. I was able to solve this in this project by changing the edit so I did not need to censor the edge. But the problem is still very annoying.

The files are shot in 4k with an A7sIII and the project dimensions are 3840x1920
