Kinds of Movie Maker

Windows Live Movie Maker 2009

Microsoft completely rewrote Movie Maker in 2009, and did not bundle Movie Maker within Windows 7. Instead Microsoft released Movie Maker as part of the Windows Live Essentials suite (Wave 3). As such, the application was also renamed as "Windows Live Movie Maker". The application was first released in beta form on September 17, 2008 and the final version was officially released on August 19, 2009.

Windows Live Movie Maker 2009 was not compatible with versions of Microsoft Windows prior to Windows Vista.

Windows Live Movie Maker 2011

Windows Live Movie Maker 2011 reintroduced the ability (which was missing from the Windows Live Movie Maker 2009) to add files to your project that are stored on network devices, such as servers. The new version also included the ability to record video clips from a Webcam, as well as inclusion of new animated video titles.On June 24, 2010, the beta version of Windows Live Movie Maker 2011 (Wave 4) was released and shortly after on August 17, 2010, a beta refresh version was released to the public. The final version of Windows Live Movie Maker 2011 was released on September 30, 2010. With the 2011 release, users must install Windows Live Photo Gallery when installing Windows Live Movie Maker, and vice versa.

Movie Maker 2012

The 2012 version was released on August 7, 2012 for Windows 7 and Windows 8 users, and dropped the Live part of the title to be known officially as Windows Movie Maker 2012. Part of Windows Essentials 2012 (Wave 5), the software included new features including audio narration, audio waveforms, audio ducking and emphasis, Vimeo music store integration, support for H.264/MPEG-4 AVCencoding, customizable outlined text, and auto-save features, as well as video stabilization and rolling shutter correction for Windows 8 users.
