3D Movie Maker

3D Movie Maker (commonly shortened to 3DMM) is a discontinued children's computer program developed by Microsoft Home's Microsoft Kids subsidiary released in 1995. Using the program, users can make films by placing 3D characters and props into pre-rendered environments, as well as adding actions, sound effects, music, text, speech and special effects. Movies are then saved in the .3mm file format.

The program features two helper characters to guide users through the various features of the program: The character McZee (voiced by Michael Shapiro), shared from other Microsoft Kids products like Creative Writer, provides help throughout the studio while his assistant Melanie provides other various tutorials.
