I am trying to make sure that imovie 10 is not unnessarily taking up disk space. Previously, imovie 9 was pretty simple and did not create these imovie theater and library files, and I knew where to delete the events files that were copied into imove for editing. In imovie 10 however, I have not been able to find any files lingering in the events folder even though it looks as though (given the processing clock displayed) importing files into imovie 10 does involve copying without asking the user to chose like in imovie 9.

 

Question 1: does imovie 10 store the events files somewhere else and need to be deleted to recover disk space?

 

Question 2: there is this huge 14GB+ "imovie library.imovielibrary" file sitting in my movies folder. Is there a way get rid of it or shrink it? All the files that I "share" (ie output) from imovie are stored elsewhere within my movies folder (and then backed up). I really can use any disk space I can free up from imovie. I have already deleted the theater files that serve no useful purpose to me.

 

Thanks a lot.

    iMovie 10 stores all your Events (as well as your Projects and other related files) in the iMovie Library.

     

    Right-click on it and choose Show Package Contents and you can see what's inside.

     

    However, you shouldn't move, rename or otherwise change the contents of the iMovie Library in the Finder or you can really mess up iMovie.

     

    If you want to delete Events or Projects, do it from within iMovie.

    Thanks for the response, Matt. I did just find out I could show all the rejected clips in imovie. I selected all of them and deleted them. The imovie library file now is shrunk to 2.93GB. Still mysteriously large but a lot better than before. Any idea what those 2.93GB would represent and how I can get rid of that? Thanks.

    Do you have any Events in iMovie?

     

    That's probably what the 2.93GB is.

     

    You might want to consider getting a external drive to use with iMovie.

    Clear, concise, and to the point. Thanks a lot Matt.

    A couple of thoughts....

     

    When you convert your projects and events to iMovie 10 from iMovie 11, you have the option to keep your iMovie 11 Events and projects intact so you can continue to use iMovie 11.

     

    If you took this option, it uses hard links so that both iMovie 11 and iMovie 10 can access the same clips but not take up double the space.

     

    This has other implications:

    1) If you delete your iMovie 10 event, it does not save you any space. You have to delete both the iMovie 10 and the iMovie 11 event to get back the space.

    2) Hard links do not work when you copy to a new drive, so if you copy your iMovie 10 and your iMovie 11 events over to a new drive, now they will take up twice the space.

    3) Therefore, if you are thinking of moving to a new drive, you should move the iMovie 11 events and projects over (from within iMovie 11). Then open iMovie 10 and convert the iMovie 11 stuff to iMovie 10, and it will use hard links and not take up double the space.

     

    Hard links are also used in Time Machine so you can have the same file assigned to multiple dates without taking up more room. Also used in Final Cut Pro X extensively. For example, you can import your iMovie Events into FCP without doubling up space.

    Here's my problem Re: Freeing up disk space, iMovie 10.0

    I followed your advice and went to events and deleted everything in there.

    I managed to gain 30GB so it's not that bad anymore.

    Still, 20 GB for 1 video is a lot of space.

    How can I make sure I can get rid of this?

    Thanks in anticipation for your kind help.

    What I have found is that iMovie 10 makes multiple copies of a video. One in the Library (maybe more, I haven't had time to fully research this), sometimes 2 in the Theater (not sure why 2) and who knows where else there are duplicates. And quite often duplicates of Event files. Not to mention pulling stills and video that you might temporarily attach to your movie, then leaving them there even after you delete them from the movie.

    Seems Apple is trying to generate sales of external hard drives.

    iMovie v9 was so straight forward on this subject it will be hard to deal with the new method of iMovie 10.

    BTW, are all of you aware that iMovie v9 will NOT work with El Capitan?
