AutoCad – a professional 2D and 3D drafting tool – can create animations using an application extension called AutoFlix. AutoFlix files contain commands that describe the motion of a virtual camera along a rendered representation of your drawing in two-dimensional and three-dimensional space. AutoFlix files have the ".mvi" file extension. The commands within the MVI file also command AutoCad to record the resulting animation in the MOV video file format.
The technical and marketing materials for audio-visual computer-related are often teaming with cryptic three-letter abbreviations, acronyms and file extensions. Many of these character triplets are trademarked names and give little if any indication of their meaning or purpose. MVI is an example of these alphabetical triads whose meaning varies depending upon the context in which it is used.
AutoCad MVI Files
Digital Video Camera Format
Some digital video cameras will save your movie in the "musical video interactive," or MVI, file format. One company's video camera uses the characters "MVI_" as a file name prefix and ".mvi" file name extension. MVI movie files play on devices that can play AVI movie. Some media players, however, require that MVI files be converted into another format like QuickTime, WMV, ASF or MP4 before they can be used.
MVI can also stand for “Music Video Interactive,” a company and a proprietary method of recording music on DVDs. Music Video Interactive DVDs may contain high-quality music audio, music videos and clips, exclusive interviews, behind-the-scenes looks, ring tones, song lyrics, screen savers, wallpaper, chat icons, and photo galleries. MVI DVDs can play on standard DVD players and Windows or Mac PCs that have a DVD drive. MVI DVDs played on computers may have links to even more features online.
Motion Pixels MVI
Finally, MVI was the name for a file extension, video compression and decompression codec for Windows computers developed by Motion Pixels. The earliest use for Motion Pixels MVI was for CD-ROM-based Windows video games. Motion Pixels MVI was also used for recording and playing movies on CD-ROMs. Motion Pixels MVI content ran best under a proprietary player optimized for Windows DOS mode. The company also produced codec to permit MVI playback under Video for Windows.
