iMovie '13 - Video rendering error: -50

Am i the only one for who this fix didnt work??

Nope didn't work for me either. Deleted all the files as described, relauched iMovie and the "share" function is still dead. Very frustrating!!

Me neither. THis is exxtremely frustrating !

Are any of you that this didn't work for running MacKeeper by any chance? That seems to be causing a lot of problems. The fix is to uninstall MacKeeper, then re-install iMovie.

I would never put MacKeeper on any of my machines.

But you have me thinking that maybe a reinstall of iMovie might help anyway ??

I have friends who upgraded and the upgrade was clearly incomplete... I wonder if mine is incomplete but to a lesser extent. I really can't believe how bad iMovie is working..

This Works! Well done Lizard King! The only difference for me was that I went into /movies/iMovie Library/Updated Projects/Render Files and then deleted anything that was under the 3 folders in /Render Files. Seemed to do the trick and even freed up a ton of disk space. Thank you! Just saved my bacon!

I had this same problem and fixed it by downsizing a background image. I was trying to do a green-screen effect, but my original background image came from a very high-MP camera (resulting in a 20 megabyte file). When I eventually downgraded the file to fit the 1080 x 1920 framesize of the video, the video would finally save.

Hope that helps!

I had the same issue rendering a video in iMovie 10.0.2 on OS X 10.9.1 on a mid 2009 MacBook Pro 2.8 and 8gb 1066 ram. I had tried everything i came accross on the forums but nothing helped. What did the trick is that I was using my internal video card and I swithed to the dedicated one. BAM! all is well now.

Hope this helps somebody!

Thanks DrewLane. Removing Render file contents did it for me. Glad I knew how to open iMovie Library by right clicking on it and selecting "open package contents".

I had the same problem on a quite long project 4 hours with 340 clips. Here my solution :

- in the finder right clic on « iMovie library » then « Show Package Contents », open the event file concerned then « Original Media » check if it matches exactly your event inside the iMovie app (number of clips, sound, songs...).

- Go back to your event file in the finder then trash all the files in « Render Files ».

Close and open iMovie app and try export again.

hope this helps.

These steps do not work for me. I'm unable to Share an iMove 10 movie (created from .mp4 files from my video camera) to a file or to share on FB - I get the -50 error every time. I've had numerous other problems with iMovie 10. I've gone back to iMovie 9.0.9 which has no problem at all sharing.

Hi,

I would like to try this as my movie cancels halfway through and can not be shared. HOwever, I have spent so many hours making this movie - when I delete the files in the three rendering folders will I lose my project or could I potentially lose my project?

It's quite frustrating that I can't save it or back it up.

Help please!

New to Apple having decided to move away from Windows.

So I have made a video in iMovies and cant share due to this error -50. So very frustrating.

Where do I even find the render section to remove file content?

A step by step screen tutorial would be useful.

Apologies for me learnimg Apple Mac is like learning a whiole new language.

I had the same problem. I was doing an 8-min video for a project and it kept saying rendering error -50, and that the file failed to share. What worked out for me was this:

Open the file in timeline

Press cmd + A (to select all the clips)

cmd + C (to copy all clips)

(create new movie)

cmd + V (to paste it into a new movie)

Apparently you have to create another movie to replace the one that has a kind of bug or something. And then delete the old one.

Hope this helped. And thank you to whoever discovered this technique. 🙂 Credits go to that person.
