Misery loves company. I thought I had messed something up in iMovie, but this thread proves it's not just me!
Issue Summary:
1) Been using iMovie successfully to import raw footage, create projects, and share to Vimeo.
2) Upgraded to Yosemite (10.10.2) and to iMovie 10.0.7.
3) Also moved library to a newly formatted external drive. All files moved easily and they are accessible. I needed to free up hard drive space.
4) Created a new project from existing footage (using the new library file in the external drive). But CANNOT share this new file to Vimeo, YouTube, to File...etc. Nothing happens when I try to share. Simply nothing.
I tried silverfoxx's recommendation and created a new library, then copied stuff over. Did not work for me.
I tried the rule of halves and took pieces of the raw imported footage...didn't work.
I brought some footage back to my Macbook's hard drive in a new library there...didn't work.
Wow...totally stumped. Fortunately for me, I didn't put a bunch of time into a new project before learning it was unsharable. However, I do need to share new projects and I'm currently dead in the water.
Has Apple focused on this at all?? Is my only solution to play with files in /System/Library ? This scares me because I don't understand the ramifications to deleting files in here.
Any help appreciated.
