Q: iMovie 11 error -49 on Lion

http://web.me.com/pondini/Time_Machine/30.html

This website explains in more detail Local Backup and how it is implemented as a hidden snapshot file on the Mac. This is automatically enabled on Laptops with Mac OS X Lion installed, and is why it hasn't started affecting people until very recently.

Turn TimeMachine off and retry the export.

yes this worked for me, thanks

Thank you. Problem solved.

I've just the same error 49!

But I don't want to turn MobileBackups off, that can't be the ultimate fix :-(

Are there any other tipps?

Thx

OMG this worked!!!! THANK YOU.

I spent 2 hours researching with no luck, then 1 hour on 2 calls to Apple Support with no luck.

Just found this thread by accident...but it works (and makes sense now).

-49 error has something to do with file permissions, so Time Machine must do something with the files during the video rendering to generate the error.

I exported a 2H03 file in 720p format with no issue while on OSX Leopard (file is 9,3gb). Then upgraded to Mountain Lion and now get Error 49. I've deleted the old event and created a new one and then got this error the first time. I shortenend the movie to 42min and can export successfully to 'Large' format but not HD. I would love to export to HD - any ideas??

I to have the same problem and have done so from leopard to lion, on all three macs I bought.

Its frustrating and scary as the mac gets so hot trying to process it all.

It will export large but not HD

how does one stop the mobile back up. I don't think I have this, as its a MBP 2011

I have taken out catchers . What to do? that did nothing.
