Have perian, flip for mac instaled. Had quicktime 7 Pro instaled but since migration to lion it does not work To.

Since Lion I can't export in 720p format. Only optimized format. Tried everything like this post

it means

opWrErr = -49, /*file already open with with write permission*/

I assume, you're using music stored on some NAS/external drive as iTunes-'Server' …?

workaround:

copy tracks needed for iM onto your local, internal harddrive, use this version.-

I am having the same issue.
I am using iMovie 11 on a macbook pro with the latestest version and update of LION.

My videos shot on my new iphone 4s and imported into iPhoto the way I have done with every other iphone before this one for years. I have never had a problem at all. ever. Till today.

and when I built the project using the clips from my iphoto library and go to export to send to youtube in HD 720, it runs for 39 mins THEN gives me this error:

The project could not be prepared for publishing because an error occurred. (File already open with with write permission)

I really do not see how it could be a permission issue since it is a file in my harddrive from an apple phone to my apple iphoto used by my apple imovie...

and until today it worked perfectly... ARRRRRGGGGGHHH!

Can someone please let me know what to do to fix this error. I have removed any network connections, rebooted to make sure nothing was working in the background but no luck. It just started doing this the other day. I thought it was because I converted a video to use but this is straight from the camera with no extra music only chapter markers and titles.

Help

I'm having the same issue with video directly imported from my Sony Handycam. I have been importing the video, creating projects, and exporting these projects using quicktime to my desktop for a month or two now. All of the sudden I was getting errors when trying to import video, they said clip failed to import. After retrying multiple time i finally got all the clips onto my macbook pro. Now when i try to export them I get the error. I have also deleted and re-imported the clips. I will try rebooting, and then export it again to somewhere other than my desktop.

OK,

I found a way to turn around.

1- download Houdini

2- start imovie and let the project ready

3- start movie encode

4- with Houdini and erase all quicktime hidden files on desktop, documents and movie folders. There were big files bigger than 6 GB, I erased all.

Tried this way to times and everything goes ok. I could export my movies complete in HD 720p !!!

I hope it works for you to.

Lets wait apple launch a definitive solution.

Exactly the same issue here. It worked until I upgraded to Lion. I've spent the last two weeks of evenings editing a movie and now I can't export it. Tried all the suggested 'fixes' but nothing helps. Do Apple even acknowledge that there is an issue yet? It seems to me that iMovie is fundamentally broken at the moment.

The Same issue, installed Lion to a clean Hard Drive, not upgrade, the system is fully updated, its a macbookpro 13 inch mid 2009 with imovie 2011.

I have imported the video directly from my iphone 4

edited as normally, no fancy effects

exported to 720p and i get the -49 error.

firt time exported to movies folder

second time to desktop

same result, error -49

i've also checked file permissions to write&read for everyone

Hope it get solved soon, any one with this config?

It seems like there's a number of these being posted all around the iMovie Discussion Group. So the solution posted most recently that seems to work for the largest number of people is this:

This requires using the Terminal app, in your Applications/Utilities folder

To turn off Time Machine snapshots type in the following command:

sudo tmutil disablelocal

The Mac will likely ask for your password, so type it in and hit the return key. The type the word, exit and hit return. Quit Terminal.

It should be the same password you have set when you first login to the Mac when it starts up. Unless you have a blank password set, then I think you would just have to hit Enter when the password prompt comes up.

When you type a password on console, it keeps blank, no characters shown while you type

It's a common thing on unix based system,.

So type your password once, press enter

And type again.

The solution involving disabling time machine or disabling the snap shot feature when you

Don't have an external hd atatched seems to work.

Hope it helps

Hello Karsten

The error message reads as follows:

The project could not be prepared for publishing because an error occurred. (-50)

Could you please give me some advice? Or anyone ?

i would appreciate any help

thanks

Guys, I just want to echo what has worked for me after receiving the error code -49 message: If you have Time Machine running (I'm exporting the Movie to an external drive) TURN IT OFF!!

I did this and voila! My movie rendered in HD, without the need for the Terminal workaround that has been posted. Good luck all. 😎

It's because Time Machine (on the MacBook only) tries to create something called a local backup, at the same time that iMovie is trying to export the movie. This locks the file so that iMovie can't write to it, so the export fails.

You don't have to turn off Time Machine, just disable the local backup feature, which is useless

anyway.
