To many Mac users with not very recent machines, iMovie 3 seemed, from the point of view of the efficiency of the interface, a step backwards, certainly not for the new powerful and interesting effects, for the well-studied audio libraries and for the interaction with the other applications but the idiosyncrasies of the interface and some unwanted slowdowns: many of these problems probably depend on the relative youth of this application which, despite the continuity of the versions, seems to have been redesigned from scratch.
This page promises to provide you with recommendations for correct installation, for subsequent optimization and for solving some problems that may arise in the current use of the application.
Hold on dear iMovie 2 First of all, the advice, especially for those with non-latest generation machines, to keep a copy of the previous version of iMovie, 2.1.2: among other things, the new software is not compatible with "conchiglioni" iBooks equipped with firewire and a 12 ″ 800 × 600 pixel screen: the necessary resolution of 1024 × 768 pixels.
To keep the previous version, it is sufficient to bring the application in a folder different from those of the applications: the preferences of the two versions are different and the update that would only replace the previous application has no effect on the previous settings. to subsequently re-extract version 2 from the Mac OS X installation discs with an ad hoc software such as Pacifist that takes only the iMovie file from the disc.The two software cannot run simultaneously on the same machine but can coexist, with different names on the same hard disk.
Optimization after installation Once the new iMovie 3 package is installed either from the web or from the disks supplied with iLife, it is absolutely advisable to do a repair of the privileges with the special utility made available by Apple. We will never tire of repeating it, the repair of the privileges is one of the operations of maintenance to be performed as in the past the "desktop reconstruction" was performed with Mac OS 9. Run it once a week or at least once a month: you will find that all applications will benefit from it. Here is how to repair the privileges. Disk Utility application present in the Utility folder in turn present in the Applications folder. Choose the tab called "SOS" in the main window. Select the disk containing the Mac OS X you are using. Press the "Repair Disk Privileges" button. This will start a routine that will fix all the privileges, especially those of iMovie that have been changed in the transition from one version to another. 'else.
Another optimization operation is obtained by launching the freeware MacJanitor application: we explain in this page where to find it and how to use it. Launch it in the full version of the controls immediately after the reconstruction of the permits and you will also benefit from this.
And if you want to take a further step in the "cleaning" of your Hard Disk, useful not only for iMovie, you can run the X Cache-Out application that cleans up the various caches of your hard disk, left by programs that may no longer be present or updated.
Full screen Perhaps many users have not noticed but iMovie 3 uses the screen differently from the previous version: while with iMovie 2 the application took total possession of the video, also hiding the dock, in this case the window of the new version totally resizable and notices the size and presence of the dock. This fact on the one hand allows a congruence of behavior with the other applications, on the other it seems to cause a slowdown in the interaction …
