Why VQVAE？

[SuSuYMH]

Hi, great work!
But i am confused that why do u encode motion using motion VQVAE ? As far as i know ,many works aims to generate motion and it is convenient to use the decoder of VQVAE . But MotionLLM is an UNDERSTANDING model , so is that any reason to implement the VQVAE when encoding the motion modality?

BTW, the encoder of VQVAE will cause the loss of information when the motion modality is transformed into discrete.🤔
