CMV format originates from old Corel Move! application software that was long time ago part of CorelDRAW until it was discontinued with version 6.0.
If you still own old CDs with CorelDRAW 5.0 ore older, you should be able to make .cmv files from various source materials, including graphics in JPEG. You might still find old versions of Corel software on abandonware websites too.
Except for that, we do not have information about any modern software that can be used for the purpose of jpeg to cmv conversion. The CMVParser utility that you can still find on the Internet allows some operations with CMV files though,
