iMovie '11 Unable to prepare project for publishing "export" error -50
Hi There,
I'm running a studio of Mac Pros running Mac OSX 10.7.4 and iMovie '11 (9.0.4).
The students using the macs today were editing a project imported from panasonic HDC-TM900 camcorders (AVCHD).
75% of the student's projects exported fine. But there were three projects which came up with this "Error -50" message after selecting "Share/Export Movie" export movie at HD720p.
The export window appears but immediately dissappears and the following message appears:
We tried the following all to no effect:
- Consolidating media
- Moving whole project and media to an external drive and trying to export on another machine
- converting .mp3 audio tracks to .aiff and then .wav
- Restarting iMovie, logging off and on again, restarting Mac
- Closing all other programmes
- Repairing disk permissions
- Verifying disk for errors
- Download and installed fresh version of iMovie'11 ( 9.0.4).
In the end we found that on each project the clips below 1.5 seconds were causing the issue. On each project there were lots of clips below 1.5 second i.e. below:
By deleting the short clips or increasing their length I was able to export.
But this can't be so! iMovie must be able to handle multiple clips under 1.5 seconds. iMovie '09 did!
I was able to import the i'Movie project to Final Cut Pro X and export from FCPX without any issues so I'm certain it's nothing to do with the footage.
If anyone has had a similar issue please post below, or if anyone has a resolution then please also post.
With thanks in advance.
