Is this Motion Blur? Or?

I have motion blur disabled in my post process, yet when I’m moving I still get this color streak effect.

What is this and how do I get rid of it?

My character is falling in the screenshot.

Any help would be appreciated!

It is a product of the Temporal AA (Project settings - Rendering - Default Settings)

There are three types you can use, the default is TAA (Temporal)
You can try FXAA and MSAA to see if they work any better.

Thank you, that definitely was the issue. I didnt see MSAA in the list though, just FXAA and TAA. too bad the FXAA gives ugly white edges and crawling jaggies.

I am not sure what determines if you have MSAA as an option.

If you go with FXAA, you can use post-processing to smudge the edges a little and make them a lot less obvious.
