Burning your Project to Disc
* Save your iMovie project.
* Choose File/Burn Project to Disc...
* At the "Create a Project Archive?" alert window, click on OK.
* When the "Burn Disk" window appears, insert a DVD-R (preferred) or DVD+R or CD into your "Super Drive". Once the window says, "Ready to burn", click on the "Burn" button.
When the process is complete, you will see your project file on the top level of the DVD (or CD). That file can be copied back to any Macintosh computer so that you can resume work on your project.
Of het comprimeert weet ik (nog) niet....
