found on another forum about USM video files, but mentioned directly witcher2 & deus ex human revolution USM video files......

Finally able to correctly convert USM file without any artifacts.
01. Demux USM file using VGMToolbox.

2A. Convert Video (M2V file) using Mediacoder
2B. Convert ADX Audio files (Mediacoder will do this also)
03. Remux files (MP4boxer or mkvmerge or whatever is your preference.)
I have tested this on serveral Witcher 2 USM files and the conversion process works without any artifacts.
Special thanks to all the developers for their great effort here.
