What is iMovie
iMovie is a proprietary video editing software application sold by Apple Inc. for the Mac and iOS (iPhone, iPad, iPad Mini and iPod Touch). It was originally released in 1999 as a Mac OS 8 application bundled with the first FireWire-enabled consumer Mac model – the iMac DV. Since version 3, iMovie has been an OS X-only application included with the iLife suite of Macintosh applications. iMovie imports video footage to the Mac using either the FireWire interface on most MiniDV format digital video cameras or the computer’s USB port. It can also import video and photo files from a hard drive. From there, the user can edit the photos and video clips and add titles, music, and effects, including basic color correction and video enhancement tools and transitions such as fades and slides.
Starting with version 5 (from 2005), iMovie processes high-definition video from HDV camcorders, in later versions also from AVCHD camcorders and H.264-compressed video from MPEG-4 or QuickTime Movie files (.mov)., e.g. as generated by a number of digital photo cameras with HD video recording feature. To facilitate this, iMovie/iLife installs the Apple Intermediate Codec on the system as a QuickTime component. iMovie transcodes (‘optimizes’) HD video upon ingestion (‘import’) using this codec and stores it in the QuickTime file format (.mov).
iMovie ’11 (Version 9.0) was released on October 20, 2010 as part of the iLife ’11 package. It has the ability to make trailers for home movies, more control over audio, instant replay and flash and hold effects, facial recognition, news themes, and the ability to watch the video on a Mac, iPad, iPhone/iPod touch, or Apple TV, as well as sharing on Facebook and YouTube. It now supports the AVCHD Lite format. Apple worked with Abbey Road Studios in London, England to bring original music/film scores to iMovie ’11. The music is most notably used in the “trailers” feature provided by the software. On January 6, 2011, Apple made iMovie ’11 (along with Aperture, the iWork suite, and the rest of the iLife suite) available on the then-new Mac App Store.
