IMovie Doesn't Export My Movie !!!

Hi, I've Been working on iMovie for a while, but today, I tried to export a 20 min. movie to a high quality with DV-PAL 25 FPS, it does export but it only play 9 second of the movie !!!
the file size is nearly 5 GB !!
I really need help !

it does export but it only play 9 second of the movie
What happens then? Program quits? It plays, but only black? You get a kernel panic?
Where do you play it? QT Player?
If you check the movie info in QT Pleayer, what does it say (regarding playing time for instance)?

IMovie doesn't import all movies from iPhoto - at least one solution

I noticed that iMovie 08 imported my movies from iPhoto, but strangely not all of them. A quick search of the support forums indicated many others were having the same issue.
After comparing file attributes of movies that were importing successfully into iMovie versus movies that didn't show up, I found that a rogue character ("&") was preventing iMovie from importing the file properly.
Renaming the title in iPhoto does not resolve the issue, since the file name (in Finder) remains the same. However, if I make a copy of that file outside of the iPhoto Library, rename it in Finder, then re-import it back into iPhoto, then iMovie will see it. I didn't rename the movie file inside of the iPhoto Library for fear of corrupting the library structure.
I found this to work at least with my .avi files. I still have the same issue as everyone else with iMovie not importing .mpg files that play properly in iPhoto.

Good thinking! The only way to change the filename in iPhoto is to export the movie file, import it back in, copy over comments, keywords from the old to the new movie, and then delete the old movie.

IMovie won't export my movie

Every time I try to export my movie from iMovie, I keep getting a message that states, "Unable to prepare project for publication. The project could not be prepared for publication because an error occurred. (File already open with write permission). HELP

Find the project with finder and change read write permissions to everyone?

I was attempting to burn a dvd from iMovie but after several attempts could not. Contacted tech support and they say lion iMovie doesn't support burning movies. What a rip (excuse the pun). What do I do now?

Imovie in os10 lion doesn't allow you to burn dvds. How do I do it then?

iMovie has never been able to burn DVDs.
It's iDVD that burns DVDs.
Currently the only place to get iDVD is if you buy a boxed version of iLife 09 which you can still find at places like Amazon.
There are also alternatives to iDVD. You can read about some of them here:
http://www.tuaw.com/2010/10/28/after-ilife-11-alternatives-to-idvd-and-iweb/
Depending on your movies size, it may also be possible to create a QuckTime version of it and burn that to a data DVD that others can play back on their comptuers.

Imovie can't export my movie because it "lost it"

so thanks very much iMovie for telling me the export of a 1 hour movie at the original size was going to take 6 hours. I left you on overnight so you could do this. I checked at about 4 hours and you were happily processing away. And this morning where's my effing movie? Oh, you lost it. I'll just check the system log. "Job appears to have crashed: Abort trap". What kind of error message gives details like that?

2 hours = 120 minutes
iDVD limits in time not in amount of Gbs - and this limit includes MENU. By using a very very simple one with NO animation or audio then this need of time can be reduced to about 1 minute - leaving 119 minutes to movies.
I use "Brushed Metal" from old themes and NO animation or audio to do this on SL-DVDs
If You use DL-DVDs You can put in about x2 on a single DVD
iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.2) and iDVD 6 has the two last ones
• Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
• Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.
About double on DL DVDs.
But if You need more then You can use Roxio Toast™ and here squees in about 10 hours onto a SL-DVD
BUT THE QUALITY WILL BE POOOOOR - VHS tapes recorded in LP or EP-mode will look stunning when compared - so to me this is no real option - I use Toast™ to do other things.

IMovie doesn't see GoPro movies in iPhoto

Is the GoPro the wrong formatt? Do i need to upgrade iMovie?
Thanks

Does imovie require anything else? i have the gopro hero3, my mac is OS X 10.5.8. (FYI-- i dont want to spend money to upgrade and the gopro was a gift.) What do i need to do to run it on imovie. Does anybody know an editing program under $100 that is 100% compatible with Hero3?

My Imovie won't export a movie I created, my laptop won't support new software. I need to reinstall the program but don't know how.

I would like to reinstall Imovie onto my MacBook and don't know how.

iMovie is part of iLife. It should be on the #2 gray instalation disk that came with your MacBook
While we all have MacBooks in this forum not all of us use iMovie. There's an iMovie Support Community where everybody uses iMovie. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/ilife/imovie

Hello, I am not able to export a movie in IMovie 10.0.1.

Everytime when I export a movie (for example as file, to I-Tunes or to the theatre) on my Mac Book Pro (from Februay 2013) I receive an error message. This Error Message is: "The Export of the Movie XY failed - Error during rendering of the video: -50" (I don't know if that is the exact english failurecode, because I am using the german version).
I allready reinstalled IMovie 2 times. Does anyone of you know an answer?
Best regards and thanks for help

There may be more than one cause for this error, but in most cases the project to be published includes short clips of less than about 1.5 seconds duration.
Duplicate the project. From the duplicate, delete the short clips and try to publish. If that doesn't solve the problem, see the comments of Didorx in this thread and of jguttenberg in this thread.

Ios imovie export format: .mov vs. .mp4

Can anyone please tell me how to force short (under 2 minute) iOS iMovie files to save as mp4s into Camera Roll?
I am an art & music teacher whose students create short iMovies for several assignments. After they're done, they save their movies to the camera roll -- and then attach them to our assignment in Edmodo to submit for a grade. In this last assignment, suddenly some of the kids' files are saving as mp4 and some as mov -- and I can't open the .mov files on my school-issued iPad 2 or on my home MacBook. We have never run into this problem before and I can't sort out if it is a matter of file size or what. I experimented with uploading files into email -- and sometimes they save as mp4 and sometimes as mov. Thanks for any help you can offer.

Why not?
iMovie doesn't 'hand-thru' the data; any export setting (what was your choice?) compresses the material - in your case by 50% ... did it visually do any harm? If not - no prob, hm?
And again: mov or mp4 are just wrappers, no 'format', esp. no codec - that is INSIDE the mov. Or mp4 ...

I cannot export my movies from iMovie since updating to Mavericks.

I cannot export my movies from iMovie since updating to Mavericks. I can get it into Theater then it says "Creating movie" but nothing happens. I can select share movie into a file, I can pick a name, resolution and location, but it doesn't save. I get the blue circle in the top right hand corner but nothing seems to happen. iMovie used to work perfectly, I cannot believe the update has ruined it!!!!

I have a an iMac 27" and am trying to import some videos of a friends wedding into iMovie however one of the movies won't import. It doesn't say why or give any error message or codes. All of the other movies on the card download with out a problem.

I have an iMac 27" and am trying to import some videos of a friends wedding into iMovie however one of the movies won't import. It doesn't say why or give any error message or codes.
All of the other movies on the card download with out a problem. The movie in question is not 'corrupt' as you can watch it in iMovie direct from the SD card but as soon as you try to import it, it just says 'error'. iIve tried moving the file to an external drive ( and other variations on this theme) then importing but have had no luck.
Can anyone please help me.

The mystery remains....
Thanks for the pointers. The file type is .mts (a proprietry sony one).
I have now found some video converter software (Wondershare and iSkysoft) at a cost. Either will convert this file for me into .mp4. This I can then import into iMovie without any problems. I've checked this on the trial versions and it worked well but without paying am left with a giant watermark in the video
The mystery (which I still havent solved) is why did 20 other .mts files import fine and then this one not?
If you could point me in the direction of some free .mts converter software that would be the cherry on the cake.
Thanks

Hi
Error -50 paramErr Error in user parameter list
Can there be any external hard disks - if so How is/are it/they formatted ? Must be Mac OS Extended (hfs) if used for Video.
UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.
What this means in Your situation is above me.
• free space on internal boot hard disk? How much ?
Video codec
• streamingDV, AIC etc. (not .avi, .mp4, .m4v, .wmv etc as they are containers not codecs)
Pictures
• in what format ? .jpg, .bmp, .tif, else ?
Audio
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
Trash the Preference file:
The "com.apple.iMovie.plist" file
Many users has not observed that there are TWO libraries.
• Library - at root level
• Library - in user/account folder - THIS IS THE ONE to look into
from Luke Burns
I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.
I don't know why that could cause that big of a problem, but it did..

You need more free space on your hard drive.

After phone support from apple I ended up creating a new project and adding all 117 clips back in individually till I found out what clips flagged and would not allow me to export. I had 3 I deleted and replaced and everything works now 1hr after tedious work....
Where do Your material come from
• Camera
• External hard disk
• USB-memory
And all are connected so that iMovie can find it ?

from Karsten S
Shorter clips than 1,5 sec might be one of the culptrits
Bengt cont.
Set-Up might differ
• Mac OS - most probably X.7 or more
• iMovie version - more than iM'11 v. 9.0.4
Action taken
• Finalizing project - I never do as I never understood the gain to do so
• Share as HD to iDVD - never give any gain but if it works the resulting DVD is less quality than if SD-quality was shared
fps - set
•I only use PAL (25fps)

I cannot help you because your description of the problem is very vague. First what software did you update, iOS or iMovie. Second where are you trying to export iMovie Films to?
