How do I use Live Animation Creator for Custom Rigs (Video to Animation)

I made a custom rig (see attachment) and I’m pretty sure I rigged correctly using RigEdit (also shown). I can edit/create animation for this rig normally through the editor, but when I use the live animation creator feature, it tweaks (also shown).

When using the same video with an imported rig, the animation works, do i need to rotate joints or something?

Any idea how to use the live animation creator with custom rigs?

I have also attached the arms/legs names with childs

Any help would be MUCH appreciated! :grinning:
