This looks pretty cool
its no Endorphin, but its a start.
And of course Reallusion Adds there own version of cascadeur styled AI assisted Autopose with its advanced version locked behind an annual rent wall
Cascadeur looks great for mocap cleanup. I am thinking of utilising kine fx and Houdini for these kind of jobs.
Somehow with all paid specialised tools the subscriptions pile up and Houdini seems like it can do a lot of 3D stuff, like Photoshop of 3D world.
Also Unreal is planning to add Mocap cleanup editing tools: https://portal.productboard.com/epicgames/1-unreal-engine-public-roadmap/c/1357-motion-editing
From what I have seen UE5 lacks a mature graph editor and NLA

which is why nearly every professional game dev uses Maya or Blender for Character animation and exports to UE
