Old iMovies with New Mac
I keep my iMovie files on an external hard drive. Last night I tried to import some new video footage into iMovie on my new 27" Retina iMac. Instead of saving it to my external hard drive like it did on my old computer, iMovie imported the video footage into the iMovie Library which is stored on my startup drive in the Movies folder. I'm confused as I don't seem to even have an iMovie Library file for my old movies on the external hard drive.
Questions:
• Is this iMovie Library file a new aspect of iMovie?
• How can I move the iMovie Library file to my external hard drive so future imports are saved there instead of the start-up drive?
• How can I merge my old movies with the new footage I imported last night?
Thanks in advance.
iMac with Retina 5K display, OS X Yosemite (10.10.2)
