It is a bug of MP4Box
I think I solved the problem
or used UniversalExtractor or extracted all the Hybrid_2018.02.18.1 files
or copied MP4Box.exe into the 64Bit folder and worked
now we need to understand how to solve this problem
XVid with audio mp3 lame or ac3
Instead if you convert to avi format
whatever the format mediainfo indicates
MPlayer and FFmpeg Muxer
