You are right: The qualitative aspect of movement cannot be measured with MEA (see: Ramseyer, F. T. (2020). Motion Energy Analysis (MEA). A Primer on the Assessment of Motion From Video. Journal of Counseling Psychology, 67(4), 536-549. https://doi.org/10.1037/cou0000407)
For the triadic aspect, these papers may also help:

The other aspects (speed, duration, max, etc.) are on the individual level and they can be derived from the time-series generated by MEA. (this was done in an older script in SAS, but I suggest to implement it in R according to your requirements).
