iMovie for Mac: "iMovie cannot open files in the "iMovie for iOS Project" format."

Question, asked professionally

When will iMovie for Mac be able to open iMovie for iOS projects?

Question, asked snarkily

Any reasonableexpectation that we will ever be able to edit projects--created in iMovie on our fancy new expensive phones--in iMovie on our fancy new expensive laptops?

Error Messages

iMovie for Mac: "iMovie cannot open files in the "iMovie for iOS Project" format."

iMovie for iOS: "An error occurred during export."

Frustration

Manufacturer: Apple (a multibillion dollar company)

The year: 2015

Hours lost: Three Weeks

Total costs for both devices: $4,000

Background Details

I just wasted thousands of dollars on these two hardware devices by making the rookie mistake of assuming projects were compatible across iMovie applications. However, the exported .iMovieMobile project files are in an incompatible iMovie for iOS Project format that iMovie for Mac cannot import. So I am stuck with a 15 GB .iMovieMobile project file--for an hour-long+ video--that I created and I was editing on my iPhone for weeks that I can no longer edit on my iPhone due to an error, nor potentially rescue the lost hours on my Mac, the sole reason I purchased it one day ago. The reason I can no longer edit the project on the iPhone is because iMovie for iOS suddenly stopped displaying the video of the project in preview, external display, etc. The clip snapshots remain visible and the audio remains audible, but the video appears fully black. Any attempt to export the video at any resolution generates an error message. (This error applies only to this project; other projects export without issue.) I can save to and from iTunes or iCloud without issue, but import into iMovie for Mac is unavailable for this latest version. Deleting and reinstalling the app does not resolve the issue. Nothing has resolved this issue; so I purchased the Mac as a last attempt, and it appears that I will have to begin the meticulously painful process of recreating the video from scratch with all the titling, sound effects, precise edits, transitions, organization, etc. This video was to surprise my mother for her birthday with "this is your life" footage, including my late father. It may seem like a small first-world problem, but such things carry big emotional impacts. What began as such a wonderfully intuitive and joyful experience has descended into a soul-suffering nightmare of catastrophic proportions. This software grinch stole christmas.

Likely Suspect

I believe this originated from Apple's confusingly designed iTunes client that removed videos used by iMovie for IOS during a sync, which I successfully restored back to the iPhone. This apparently resulted in iOS seeking and then claiming to find all of the videos, but somehow a bug in the coding causes the audio to play but not display video, and no way to resolve the bug from an enduser standpoint. I was hoping that iMovie for Mac would allow me a workaround, but I'll never know because the iOS and Mac formats are currently and dishearteningly incompatible.

Suggestions

I never performed a full backup of the iPhone, but I don't believe any of the iCloud nor local backups actually backup iMovie projects themselves anyway. (That's a fail.) So one must back them up manually to iTunes or iCloud.

MANUALLY BACKUP YOUR PROJECTS DAILY, IF NOT HOURLY.

MANUALLY BACKUP YOUR PROJECTS BEFORE IMPORTING OR SYNCING FROM ITUNES.

MANUALLY BACKUP YOUR PROJECTS BEFORE IMPORTING VIDEO CREATED OUTSIDE OF YOUR IOS DEVICE.

Resolutions

Hope Apple fixes this problem soon? Perhaps.

Return the Mac to Apple, if they allow? Perhaps.

Someone in this community will provide a magical workaround--that I haven't already attempted? Perhaps.

As unlikely these options may be, I shudder to imagine that I may be forced to suffer no resolution and $3,000+ completely down the drain, because if iMovie for IOS worked as intended, I wouldn't have ever purchased the Mac as a last ditch effort to rescue the project. It meant that much to me to surprise my mother by attempting to retrieve this project file from oblivion--but to no avail.
