Aero Quartet has released SimpleMoviex version 3, an updated version of their Mac OS X movie editor. A demo is available, and it costs $30 to download.
Billed as a replacement for Apple’s QuickTime Pro software, SimpleMovieX is designed to enable users of digital video on the Mac to edit their content. It extends editing capabilities beyond just .MOV formatted files to include other popular formats, such as AVI, MPEG-1, MPEG-2 (QuickTime MPEG-2 Playback Component is necessary if you want to edit MPEG-2 files, but QuickTime Pro is not required) and Google Video. No re-encoding is necessary to save those edited movies.
The 3.0 version adds the ability to add chapters within movies, batch conversion using drag and drop from the Finder; support for MPEG files larger than 4GB and AVI files larger than 1GB; improvements to audio synchronization; a keyframe indicator; a new Check for Update feature, and improved support for downloading movies from the Internet.
System requirements call for Mac OS X v10.3.
