IMovie HD 5
iMovie HD included support for HDV (720p and 1080i) and integration with the rest of the iLife suite, with toolbox buttons allowing the importing of images from iPhoto, music from iTunes and the setting of chapter markers ready for exporting to iDVD.
iMovie HD 5 imported mjpeg files as dv by default, which introduces noise; mjpeg files are cryptically lumped with "isight" files in this version.
Another new feature was included called "Magic iMovie", which attempted to automate the whole process of video editing, by allowing a common transition to be added between scenes, a music track to be synchronised with the video and a DVD to be created with the accompanying iDVD software.
