When starting a new Screen Recording in Quicktime Player in Lion 10.7.3, as soon as I click record I get this following error message:

quicktime error

Here's a video demonstrating the issue:

Here are the settings under the triangle on the right:

Works fine for me. Just putting that out there. – timothymh Mar 30 '12 at 0:00
May I ask, though, what's the input-bar-type thing between the O and N of operation? Also, there's usually correct punctuation in Apple's error messages (i.e. "The operation could not be completed." with a period). What's up? – timothymh Mar 30 '12 at 0:02
The input-bar-type thing is just a cursor that appears if you click on the message. the message isn't editable or anything, though. When I take a screenshot, the main quicktime window disappears, even with a full screenshot - (that screenshot shows you can select text with the cursor thing) – penguinrob Mar 30 '12 at 1:02
Huh, never seen that before. OK! – timothymh Mar 30 '12 at 1:14
@penguinrob What are your settings under the triangle on the right? – Kyle Cronin Mar 30 '12 at 2:06

Finally figured it out - apparently the Movies folder in my home directory had a weird permission set on it and things couldn't be written to it, which caused QuickTime to give a very descriptive message "The operation could not be completed" and saving to a different folder (or after fixing the permissions on Movies), worked.

What did you set the permissions to? – nipponese Oct 12 '15 at 20:50
@nipponese The permissions were set to "Read only" for my user account, so I changed it to "Read & Write" for my account in the Finder Get Info window, and then I could save to it. – penguinrob Oct 13 '15 at 3:40

FWIW, I ran into this issue today and the problem was with the external monitor. After unplugging the Apple Display, I was able to see the phone screen output fine.
