Thanks for your help. The need for saving the cloth animation was due to the fact I can't use the cloth animation in Cinema (interPoser doesn't import it).
Maybe I'll just learn to clothify in Cinema...

Rance01, the animation is was created using Daz's plugin aniMate.
It helps creating smooth animations, but it is limited to the packages available.
I started to convert BVH files but they require a lot of work in Poser so I stopped.

Thanks again
