Reduced hip movements

[ElviraLL]

Hey, Fantastic work! Thanks for shearing your research!

I noticed that the extrated movement from current motion tracking solutions(4d Humans, TRAM... and some other motion tracking solutions) are always have less hip movement, i.e. The hip movement in the result is not as pronounced as in the input video, do you know what might be the problem and how they can be solve?

Thank you!
