Vue will import animated Poser scene files directly, if you have the Mover plugin. Visit Phoul's website at www.belino.net to see examples of Poser animation (many done with Mimic) rendered in Vue.

Bringing Poser animations into Bryce is considerably more challenging, although konan's Natural Pose utility helps somewhat.

I don't know if the sound will be imported automatically into either application, but you can add the soundtrack to the finished movie afterward with a decent video editing utility.
