What does error -50 means?
Mac OS X 10.7.5, 27" from 2010. Have used iMovie for many years but now with a movie material somewhat over 1,5 hour the program stops after some hours when finishing the project. The system refers to error -50- What does that means? I am using chapters for the first time, may that be the reason of the problem? Is it a limit for numbers of chapters? I have used a lot of chapters.
