how to set it up

The only way I have found to circumvent this annoyance is to play a little trick on iMovie. And that trick is to move the original ~/Movies folder under a different name and put a symlink in its place (to the network folder of your choice).

Here are the steps I took from the Terminal to do this (you will need to have Administrator privileges and you will need to know where your network folder is attached):

• sudo mv ~/Movies/ ~/Movies-original
• ln -s /Volumes/my-network-volume/Movies/ ~/Movies

Now, when I load up iMovie it will use the networked volume. If you don’t like this, you can always move your ~/Movies-original folder back where it was.

remaining issues

Unfortunately, this isn’t a perfect fix. There are two caveats or issues I have found.

One, is that now my hard drive (called Papa Bear) is listed twice in the Project Library:

And two, is that when you delete an event or project from within iMovie, it moves the project into a temporary folder rather than actually deleting it. The next time you open iMovie, it will show up again. I’m sure this is because it thinks it is working with a bona fide Trash system but its not (because it is network storage. See this example:

In order to get around this annoyance, I created a Python script which removes the temporary files for me and created a cron job to run the script from time to time (cleaning up the mess iMovie leaves behind).

#!/usr/bin/env python
'''
Simple script to remove all directories that match the name:
    /iMovie Temporary Items */  [note the star!]

'''
import os
import fnmatch
import shutil

# tuple of directories to search through (you can add more than one)
DIRS = ('/Volumes/leaker-damon/tps/Videos/',)

for directory in DIRS:
    for root, dirnames, filenames in os.walk(directory):
        for directory in dirnames:
            if fnmatch.fnmatch(directory,'iMovie Temporary Items *'):
                shutil.rmtree(os.path.join(root,directory))

make this more better

Am interested to hear how other people have been handling this — this approach certainly isn’t perfect, but it seems to work (for now).
