Quick Time screen capture freezes when i'm working with Modo 3D. Any solution?

I'm using OS X Mavericks as well, and it seems like the same thing happens when I try to type in MonoDevelop, part of the Unity package. Unity works fine, it only seems as though I can't screen record typing in MonoDevelop. It looks like it's still recording, it just has the rainbow wheel of death after I try to finish out the Quicktime. I left it up for several days and ignored it, but it still didn't finish. I finally had to force quit it and reopen it and when I did it opened up the temporary file of the video I was recording, but it stopped whenever I started to type into the MonoDevelop interface. The first time it let me save the video to the desktop. The second time, the time which I left it open for days, it would not let me save it, on command-S or on exit. I don't know exactly what's wrong, but I believe that you know as much as I do. Please post a reply if you need any more information or have a fix.

I have the exact same problem cesarfig1976 while working in Modo.

Did you find out a work around? I've downloaded diff software to record my screen, and it still doesnt work!!!!

Well, Yosemite doesn't work either, so don't waste your time. thought it would have been updated. too bad, how lame.

The problem is still here in April, 2015. Quicktime also still deletes screen captures if you trim them before you save, which is has been well known for a good long time. Meanwhile Pages on iCloud still lacks basic features and features the same critical bugs it had two years ago. So I'd wager these products don't actually have anyone working on them. If Apple is so understaffed they can't maintain current products, they should abstain from pointless new ventures like SpriteKit. A 23 year old product with such narrow scope should not be in this condition.

Sorry – It seems I wrote a grumpy post in the heat of the moment and now I can't delete it. I filed a formal bug report to Apple, like an adult.
