iMovie Doesn't Import PhotoLibrary on Local or External Hard Drive

One update to this post (and now a question [3])

After selecting "Use as system photo library" from within the General tab (command ,) in the Photo's app I am now able to see media within iMovie even with the "myFile.photoslibrary" being on an external hard drive. So this appears to have answered questions [1] and [2].

However, I now have questions [3a] and [3b]:

• [3a] if I am working on a project that uses multiple "myFile.photoslibrary" library archives can I include media from more than one archive in iMovie or is there only a single "one to one" mapping between a "myFile.photoslibrary" archive and an iMovie project because selecting "Use as system photo library" from within the General tab is the only way to have iMovie discover media?
• [3b] does importing the media into an iMovie project remain persistent for each "Use as system photo library" from within the General tab?

Thanks

Ok, looks answer answers to [3a] and [3b] are that iMovie is only capable of looking at one myFile.photoslibrary at a time and that myFile.photoslibrary file bundle needs to reside on the internal hard drive of the Mac you are using. If you want to use media from more than one archive you need to export the content rom each myFile.photoslibrary and combine the subset of media you want to use for your iMovie into a new subset-of-myFiles-from-different-libraries.photoslibrary and place that file bundle on the internal hard drive. I have a (somewhat) efficient process for doing this - if anyone is interested I can post the process.

Also, if anyone from Apple has any comments on the above summary and overall process for making an iMovie from multiple PhotoLibraries that would be great.

Thanks

Actually as I explained above I do no accept this as the solution to the problem. If end users have many different photos and movies that they have grouped into different myFile.photoslibrary files then unless you follow the process I describe above they cannot create an iMovie from events that span multiple myFile.photoslibrary groups - in short this implies that the end users need make sure all the media they want for any possible project in the future is in the same photos library library today, meaning put every photo and movie you have ever taken into the same photo library.

There are a few options (one mentioned above) for approaching this iMovie use case in a better way.

Thanks for your feedback guys - I shall provide feedback to Apple although I'm sure they read these posts so that may be redundant. In the mean time if anyone wants to be more productive with multi-archive Photos libraries being used to make a single movie in iMovie

1. Create a folder on your local drive (let's call this folder mediaForMovie)
2. Simply use the Apple Photos app to browse for the media you want in each photos archive
3. Each time you find a photo you want export it to the folder in (1) above
4. Each time you find a movie you want use the "get info" menu item to get the file name for this movie - then in the Finder (file system) select "show package contents for the Photos archive you are currently using, navigate to the "Masters" folder & search for the file name you just did the "get info" on & copy this .MOV movie file to the folder in (1) above.
5. When you are done with steps (2)-(4) go to iMovie & import media from the folder in (1) above to have the media from multiple Photos archives for making your movie.

SInce this worked I'll (1)-(5) this answer solved my issue ;-)

Thanks
