Hello, Problem description: in iMovie HD 5 and onwards, the file size stays the same no matter how much you delete in your project and no matter if you empty the trash. (added the underlined after first response) Solution: 1. cut, edit, delete etc. all you want in your current project. 2. save 3. close project 4. start a new project (without importing footage yet!) 5. move the project window a bit to the side 6. highlight your original projects icon and press ctrl+mouse-click, a menue opens, choose "show package content" 7. go to the folder "cache", drag the file named "timeline" (its about 8kb big) to the project window of your new project and drop. 8. the new project will now import only the data minus the before deleted files. It will "produce" a new .dv file in the media folder (footage folder). you can prove that by press-clicking ctrl+mouse-click on the new project icon -> show "package content", go to "media" and "cache" you will find the timeline file and a .dv file called "timeline.dv" in the media folder (which will be smaller in size than the uncut footage/project). My experience: it works My question: is this really a proof way? Will we have a 1:1 copy of the DV-file minus the deleted parts? Will the data not be corrupted? Will the timecode (with audio) be totally intact? I do not have those tools you might need to check if everything is ok, I can just tell from the eye that it seems to be alright. What do you say?
