Remove Rounded Corners from QuickTime Player Video Windows
QuickTime Player automatically rounds the corners of any video window, a nice touch that fits in line with the rest of the OS X desktop and window experience. If you don’t like the rounded movie window appearance though, you can easily disable them:
- Quick QuickTime
- Launch Terminal and enter the following command:
- Relaunch QuickTime and open a movie to see the difference
defaults write com.apple.QuickTimePlayerX MGCinematicWindowDebugForceNoRoundedCorners 1
The change is obviously very subtle, but if you watch a lot of windowed movies it can be an attractive change.
If you want to get the rounded corners back, use the following defaults write command and then relaunch QuickTime Player:
defaults write com.apple.QuickTimePlayerX MGCinematicWindowDebugForceNoRoundedCorners 0
The defaults command works in practically all versions of QuickTime in Mac OS X including OS X Lion and Mountain Lion. We had covered this a while back as part of a group of QuickTime hacks but thanks to David for the reminder that it works in new versions too.
