Imovie,unable to prepare project for publishing error -50

Hi,
I'm done editting my video and i have tried all sort to export it( share- media browser, facebook, export, etc) but it keeps on giving this " unable to prepare for publishing - the project could not be prepared for publishing because an error occurred (-50)".
Help me please.
Thank You.

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 ?
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

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 ?

Bartirn,
I called Apple under my Mac support contract. They were completely unfamiliar with the error you and I were encountering. Updating to 10.8.5 didn't help.
I'm stopping my TimeCapsule while I perform these tasks, but I don't know yet if I have a consistent work-around.

I keep getting the following error message while sharing my iMovie to iDVD. "Unable to prepare project for publishing" error (-2125).

I keep getting the following error message while sharing my iMovie to iDVD. "Unable to prepare project for publishing" error (-2125). I'm running iMovie 09 v. 8.0.6 on a iMac with OSX v 10.6.8, 2Ghz core duo, 1GB 667 Mhz DDR2 SDRAM. Any ideas why?

That particular error comes up for a number of reasons, sometimes it's the size of the movie you're trying to export. Bengt Wärleby a longtime contributor to the iMovie Discussion Group has advised a number of people on this error code, so I am going to link to his latest advice he's given to anyone trying to export to DVD from iMovie: Bengt's tips for great DVDs.
Specifically, try bypassing Share to iDVD by using Share to Media Browser instead.
In the Share to Media Browser dialog box choose the Large Size.
When(If?) it gets through that process, quit iMovie altogehter then go to iDVD.
Create a new project and click on the Media button near the lower right hand side of the Project Window.
Then click the Movies button in the Browser window just above that.
Under the iMovie star icon you should see the name of the project you shared out from iMovie.
Drag that into the project and burn the DVD.
If it's still to large or you get the same -2125 error code trying to Share using the Medium size instead. But again if you really get stuck consult Bengt Warleby's User tips:

Unable to prepare project for publishing (error -2125); how do I fix this?

Trying to export movie (about 200+ gb: 3hr.s+, using external hard drive) to a thumb drive (32 gb); I get the msg. unable to prepare project for publishing. An error occurred. (-2125)
What to do?

The thumb drive is probably formatted as FAT32 (most USB flash drives are formatted as FAT32). There is a 4GB file size limit with any drives formatted as FAT32. Try reformatting the thumb drive as Mac OS Extended (Journaled) using the Mac app Disk Utility (it comes with the OS and should be in the Utilities folder).
Also, are you sure that the 32GB drive is enough space for your exported movie? Try exporting it to your internal drive, or an external portable drive formatted as Mac OS Extended (Journaled). Then copy it to the thumb drive, provided that the exported file will fit on it.
Otherwise, you will need to follow Karsten's advice to duplicate the project one or more times, then delete portions from each duplicate so that you end up with a number of separate projects, each with their individual content. Then export each project separately.
To duplicate a project, while in Project Library view (where all your projects are listed), select File > Duplicate Project. Alternatively, right-click (or Control-click) on the project in the Library and select Duplicate Project from the pop-up menu.
If you need assistance with reformatting the thumb drive, please ask.

Unable to Prepare Project for Publishing (error code -2015)

I have imported a Hi-def video from my Panasonic camera, edited it and am now trying to export it.
When I click on share ---> Export Movie ---> then click on large
I get the following error:
*Unable to prepare project for publishing*
The project could not be prepared for publishing because an error occurred. (Error code = -2015)

me no Unix expert. but -2015 reads as 'invalid time' of a movie file... whatever that means.. (?)
have you set time&date in your recording device correctly...?
have you set time&date in your Mac correctly...?
... that is only wild speculation, sorry, ... but worth a try

IMovie '09 "Unable to Prepare Project for Publishing" error (-2009)

Please help ! I have just created a small movie in iMovie '09 from imported clips from Sony Handycam with miniDV tapes. All clips imported easily and can be viewed and edited. Though when I try to share the project to iTunes or even export it to my desktop I get the message "Unable to prepare the project for publishing" error (-2009).
I have been searching the forum and the web for an answer or quick fix and I see none, though i do see that many people are having this same issue. I already have all permission set to read & write on all the appropriate folders. I don't know what else to do.....I was hoping to have this project done for a Christmas present for my wife.
Please help .... ! ! !

I think I know what was the problem in my case. My project-file wasn´t very large, but I imported all my movies in one single event. After splitting the movies up into different events, I was able to export my project....

Unable to prepare project for publishing error (-50)

Hi,
After adding a slow motion effect to one clip of the project, iMovie started to fail to preview the images when moving the mouse over clips (in the storyboard), then a few of the clips just wanished from the storyboard and became grey.
Project can't be previewed using the play button.
And I get the error (-50) pops up when trying to finalize the project.
Any idea how to fix this ?
Thanks.

I wanted to duplicated the project and try to find what's causing the issue (https://discussions.apple.com/message/18964007#18964007).
Now I see that my project is listed in the projects list as non-editable (the edit project button is greyed out).
The "duplicate project " action is disabled, too.

In iMovie I am getting this message...Unable to prepare project for publishing. The project could not be prepared for publishing because an error occurred.m file already open with write permission.

In iMovie I am getting this message...Unable to prepare project for publishing. The project could not be prepared for publishing because an error occurred. File already open with write permission.

Unable to prepare project for publishing. The project could not be prepared for publishing because an error occurred. (Error code -50) imovie 09 v8.0.6

When I try to export the movie I get this error code. Im doing a music video and have put days into it and now I can not get it to export! My other small project export with no problem.

Thanks for the details. We have a similar problem (see my post below) and are in the process of adding back each clip and then testing for export. My question is, once iMovie is unable to export the project, does it render the file "bad" and prevent exporting even if you remove the "poisned" clip(s)?
++++++++++++++++++++++++++++++++++++++++++++++++
Hello, We are having a similar problem running iMovie '09. We get the exact same error as you reported.
"Unable to prepare project for publishing" The project could not be prepared for publishing because an error occurred (-50)
We have a very similar situation were we have multiple repeated clips. However, our clips are 2.4 's. Like you, we took the finished project and started eliminating edits that we thought might be preventing it from exporting. The following actions still would not allow the project to export:
removing title pages
removing transitions
removing imported music from iTunes
removed another clip from another event
closed all other programs
closed iMovie, powered off computer, opened iMovie, tried to export
reconfirmed the last project exported would still export - it did without issueThe only difference between the project that will export and the one that does not are these short (2.4's) repeating clips
When we create the new project from the recorded event without making any edits (just as recorded), it exports without issue. We have started the arduous task of adding back in each edit and testing it for export until we determine which edit is causing it to "not export". This is a very inefficient way of troubleshooting.
This is a science project for my son and we need to be able to save it as a QT or mpeg4 movie so that he can submit it to his teacher for viewing and a grade!
Any ideas from any other users would be greatly appreciated.

Will not share Imovie with Idvd. Gets so far and then a box saying Unable to prepare project for publishing because an error occured (-41)

Cannot SHARE project from IMovie to Idvd. Gets so far and then a box with a message saying Unable to prepare project for publishing because an error occured (-41).

Bengt is as always entirely correct, but another meaning of error -41 is that you have chosen the wrong encoding setting for the length of video you have:
iDVD encoding settings:
http://support.apple.com/kb/HT1502?viewlocale=en_US
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
That was for single-layer DVDs. Double these numbers for dual-layer DVDs.
Professional Quality: The Professional Quality option uses advanced two-pass technology to encode your video (The first pass determines which parts of the movie can be given greater compresson without quality loss and which parts can’t. The second pass then encodes those different parts accordingly) , resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

When I go to download my iMovie to iTunes I get the following message "Unable to prepare project for publishing. That project could not be prepared for publishing because a error occurred"(disk full). What do I need to do?

When I go to share my Imovie to Itunes after a couple of hours I get the following message. "Unable to prepare project for publishing. That project could not be prepared for publishing because a error occurred(disk full)". What does this mean and how do I fix it?

This is the forum for iOS (iPhones and iPads),
I have refered it to get moved to the correct forum.
But my guess is that you have to clear space on your harddrive.
The video gets rendered when you out put it, so you will need lots of space to do so.

Error on imovie11: Unable to prepare project for publishing.

Error on imovie11: Unable to prepare project for publishing.
I badly need someone that is an extreme expert on Mac Pro and imovie11 and very good at troubleshooting. I have a critical project to get out and have serious problem. Mac store solutions did not work. Need a Pro that I can hire to come to my office in Raleigh NC.
Cleared the memory space on the drive, cleared the preferences.. critical problem. Love to find someone good to hire in the Raleigh NC area that come over and work on it.

Apple Store advice did not work.

Rocker-65 is correct, large, long and complex projects can have problems resulting in a Error-108. Sometimes cutting a Project up into pieces or just cutting into 2 can help. Easiest way to accomplish the cutting is to create a Duplicate Project. Then just cut Project 1 in half, saving the first part. Duplicate Project gets cut in half and contains the second part.
Then if you want to stitch them back together, export each project individually at 720p. Import each one BACK into a new Event Folder in iMovie and combine then in a new Project, export that.
