Q: Cannot export movie files from iPhoto 11 (9.5)

sorry. i meant i don't know the reason at all.

FYI. my iPhoto Library is located at the external hard drive via thunderbolt.

TEST 1.

created a new iPhoto Library(A) in my MBP's SSD.

copy some movie clips has exporting problem to desktop.

importing the movie clips to A.

exporting. fine.

TEST 2.

created a new iPhoto Library(B) in my external hard drive.

copy some movie clips has exporting problem to external hard drive.

importing the movie clips to B.

exporting. fine. BUT exporting doesn't work sooner or later.

i don't know why. just it doesn't work.

i gave up. i tried all i know. and still don't know why.

What format is the external disk?

Mac OS Extended (Journaled)

Have you got anything back from Apple? They must come out with some kind og update soon to fix the problem, dont you think?

I get the same error in Mavericks 10.90.1 on my late 2013 iMac in iPhoto 9.5.1

To get around it,

I created a Smart Album containing only videos then "Select All" and dragged all the videos to an empty folder in the Finder.  They all exported fine as QT movies.

Alternatively, open iMovie and choose 'iPhoto Library" then the Smart Album containing the Videos and voila, create your project and edit videos from there.

Maybe the "workflow" has changed and you can no longer export videos using the "export originals" in iPhoto, but you just drag them out, which really is simpler or access the files directly from iMovie.

Hope this helps.

I just ran a test with iPhot 9.5.1 on exporting movies out of iPhoto via the File ➙ Export ➙ File Export menu option with Kind = Original or Current or JPEG or any of the options.

With each and every format option I got the error message "File Not Found".

Why, because iPhoto is looking in the Previews folder for the file in every case and not the Masters folder:

I tried it with two different libraries with the same result.  I can, however, just drag and drop the movies from the library to the Desktop and get the original movie files. 'Tiss a puzzlement.

Created a new library, ran the same test with the same results: when iPhoto goes to export a movie file it looks in the Preview folder of the library for the file.

I changed the extension of a jpeg file to .mov and imported it.  When I went to export iPhoto looked in the Previews folder for the file.  The problem is limited to any movie/video file.

I got sort of he same. From one library, it exported 2 of 14 movies. For the others it looked in the Preview folder.

I exported all of them using Aperture (unified library), then imported all to a new iPhoto library.

They all exported from there without a problem.

So there's no consistency.

Alright,

I had this problem and just fixed mine.  It was driving me nuts in that I couldn't export the videos.

Fix for me,

Hold Command +option while opening iphoto until you get the diag box.

Choose the second option to Rebuild Thumbnails.

Wait forever for it do that and try exporting.

So far I have been able to export any movie I have chosen so far.

It seems the thumbnails are what is being linked to the master/preview libraries.

I'm having the same issue, but now I'm also having issues on import.

I tried to import a folder that contains a bunch of picutres and .mp4 files (Lumia phone).  Of the 72 .mp4 files, I got an error that 4 failed to import, the rest were fine.  The 4 that didn't import, play just fine in Quick Time.

Is anyone else having this issue?

how do you hold down Command +option, i know the cmd  but what is the +option?

sorry for beeing newbie

Option = Alt

I'm having same problem with exporting videos, on my late 2013 MacBook Pro Retina running Mavericks.

I tried rebuilding thumbnails as suggested earlier in this thread, but that didn't fix the problem. I still get "Unable to prepare video for export" error when trying to export, and looks like iPhoto is trying to find movie in the Preview folder.

Just dragging a movie from iPhoto to a folder in Finder is correctly copying it though, so that's the workaround I'm using for now.

This seems to be what many of us are seeing, and at least for me, it was just in one library.

I had a chat with the iPhoto shop at AppleCare and they really didn't seem to understand the problem.

It's especially a problem now that we can put video in Shared Photostreams  and get them into iPhoto. Getting them out seems to be another story.

I did a repair permissions first, rebuild thumbnails after that. I don't think I did rebuild database. However I could have. Give it a go! I started at the top and worked down trying the export after each.

WORKAROUND SUGGESTION:

Created a Smart Album of Just Video File extensions. Then just Selected all and dragged and dropped all in the new album to a folder in Finder.
