Converting .zix files to .mp4 format.
ZIX archives are known to be distributed on torrents or other file sharing sites, but are nothing more than a slightly altered variant of ZIP that can be opened only with a malware program known as WinZIX. Some videos (MP4 files for example) can be found packed in a ZIX archive, which makes users look for a ZIX to MP4 conversion.
The best advice we can give you is to not bother with ZIX files at all, and to not download them either. In case you have no other option, use tools such as UnZixWin, which allow users to remove trash data from these archives and to generate regular ZIP files.
You can then simply convert ZIP to MP4.
