What is a MVI file?
Contains instructions and commands for a movie or animation created with AutoCAD, a 3D-modeling program; generated by AutoFlix, an animation add-on for early versions of AutoCAD.
NOTE: Canon PowerShot digital cameras save recorded movie files with a name beginning with "MVI_." These files are not related to AutoCAD, but are standard .AVI movie files that can be opened with a video player.
