Thanks to gadgets like your iPhone and the fact that you can shoot relatively inexpensive HD footage using camcorders (and even digital SLRs), you will soon find that your poor hard drive is beginning to groan under the weight of all that footage. As well as losing valuable disk space you will also find that asset management becomes a problem, as it can take ages for you to find specific clips – but by having ‘favourite’ and ‘rejected’ clips, finding specific clips becomes much easier. Fortunately, iMovie has some handy tools to help you sort out the wheat from the chaff and make your projects tidier, not to mention saving some valuable disk space at the same time. So, follow the nine steps over the page and get ready to spring clean that hard drive!
