For video editing on a G4 Mac running Tiger 10.4.9, iMovie is a recommended option, especially for basic tasks like digitizing VHS tapes and creating DVDs. Users have noted that older versions of iMovie, included in the iLife suite, are suitable for simple editing needs. However, newer versions of iMovie, like iLife '08, do not support G4 processors and have shifted focus away from traditional video editing to video organization, leading to dissatisfaction among users. Alternatives for video editing software can be found on dedicated websites, with some options available for free. For transferring large applications like GarageBand, using an external hard drive or a broadband network is suggested, as Apple does not provide these applications for direct download. Users have also discussed the availability of iLife '06, which is compatible with G4 systems, as a viable option for those needing an upgrade.
