TAA Ghosting

I’m getting very bad ghosting using the TAA effect in the Post Processing Stack. It’s with objects that move, primarily skinned meshes. The ghosting mostly only occurs when grass is behind the characters, otherwise it’s barely noticeable. Any ideas how to resolve this?

Here is how Guerrilla Games resolved it - https://forums.unrealengine.com/development-discussion/rendering/125166-whats-wrong-with-epic-anti-aliasing-technology-and-terrible-fxaa-quality?p=1042185#post1042185
