Google translate result: Hi all,
Problem: "publish" The my iMovie projects terminates immediately. Free disk space: 240 GB (that should be enough I suppose!).
Dr Google knows the problem, but knows not the solution. What caused the following error and how can I fix him?
The project could not be prepared for publishing because an error has occurred. (-50)

A. To put You in same situation as me - I should answer in Swedish - but the polite language here is in English so I keep to this to the benefit of most of the readers.
B. This is not - Apple - It is a discussion forum - run by Apple - by totally relying on USER - helping other - USERS - Apple rarely reads this or participate in answering. It's very voluntary business
C. 240GB free space on Start-up hard disk is well more then enough IF - one work with interlaced SD-Video as I do - my minimum is 25Gb and ONLY the Main Start-up hard disk is of importance as it's where iMovie, iDVD and Mac OS stores their temp.files (can not be addressed elsewhere)
If You work in full HD - this needed space will be at least 4 - 5 times more.
D. Error -50 paramErr Error in user parameter list
• Is TimeMachine running - Set the TM-Application to OFF
• 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.
• in what codec ? (not just .mov, .mp4 etc - BUT open it with QuickTime-player then open Inspector and read - Video Format/Codec: nnnnnnnn
What does it read ?
• in what format ? .jpg, .bmp, .tif, else ?
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
Trash the "com.apple.iMovie.plist" file
Many users has not observed that there are TWO libraries.
• Library - at root level (when You open main hard disk)
• Library - in user/account folder - THIS IS THE ONE to look into and into preferences

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..

first of al I want to thank you for your quick and extensive feedback. Let me see if I'm getting through it.
A: I bow my head knee-deep in shame. Please pardon my impoliteness.
B: Well, good to know, thanks for the hint.
C: Since I'm working in SD the disk space should not be the problem in this case. 4-5 times for HD? Wow, thats loads of data!
D: Time Machine = off BUT ...
- the original movie file lays on a NAS-Drive - I'm just trying to find out how it's formatted but it seems that "Festplattendienstprogramm" Disk-Utility (??) can't access this HDD via WLan. I'm quite sure it was NTFS formatted.
- during importing the video into iMovie I set the option "copy", now project-file als well as importet video files (now in *.mov) are stored on the internal HDD (Start-Up-Drive) --> so for publishing there should no need for accessing the NAS-Drive
Quicktime and Command+I says:
JVT/AVC Coding, 576 x 320
AAC, 48000 Hz, Stereo (L R)
Thanks & greetings,
Hi, i have the same problem on my Macbook OSX 10.6.8. (Error-50). I tried all the solutions that were described here, but nothing helped.
I also tried to put the project on my iMac but i have the same problem here. I can export any videos i made but not this one. I don't want to start over again because i worked on this for some weeks and can never finish in time for the final presentation in university.
The only thing I didnt understand is how to open the video in quicktime to find out the video codec stuff. All my videos were recorded with the isight camera, so that shouldnt be the problem. My last isight camera project worked just fine.
Audio is mp3.
Tried changing reading and writing rights.
TM turned off.
No external harddrive used for the project itself, but it is formated right.
150GB free space.
Deleted the i.Movie plist file but it comes back as soon as i delete it. Weird.
The only thing I didnt understand is how to open the video in quicktime to find out the video codec stuff.
• If You find the movie file You made with Your iSight Camera. Then drop this on one of the QuickTime icons.
Then open inspector or [ cmd+I ] and read
Video Format/Codec: nnnnnnnn
What does it say ?
Audio is mp3.
I NEVER use .mp3 or other audio format than .aiff (44.1kHz from Audio-CDs and 16-bit 48kHz else)
Only things I can figure till You tell the Video-Codec.

Hi, thinks for your help.
I found the problem now:
My 2 1/2 minute movie consists of 26 very short videos. One of them was causing problems. I found this out by deleting one by one and seeing which one was the "evil" one. I tried to export the movie after each video I had deleted; I also had to try to delete a few at a time, since I used some videos multiples times. Sometimes iMovie crashed when I previews the video... Then I was pretty sure I had found the right one.
Then I took the raw material of the evil video from the finder and opened it in quicktime and saved it again. Then I imported this new video back in iMovie and replaced the old video. Now everything works again.
It took hours to find the bad video but Im glad it worked somehow.
