Each is to be typed into a Terminal window after you've first quit QuickTime
Player.
Make the Playback Window Square
By default the corners of the QuickTime Player window are rounded a little
to create a pleasing look, but for those who like to see everything that's going
on in each frame of a movie, this can be annoying.
The following command will make the playback window fully square:
DEFAULTS WRITE COM.APPLE.QUICKTIMEPLAYERX
MGCINEMATICWINDOWDEBUGFORCENOROUNDEDCORNERS -BOOL TRUE
To restore rounded edges later, use the following command:
DEFAULTS DELETE COM.APPLE.QUICKTIMEPLAYERX
MGCINEMATICWINDOWDEBUGFORCENOROUNDEDCORNERS
Automatically Start Playing Upon Opening a Movie
By default QuickTime Player won't start playing a movie you open until you
click the Play button on the controller bar. The following setting will cause
movies to start playing automatically:
DEFAULTS WRITE COM.APPLE.QUICKTIMEPLAYERX MGPLAYMOVIEONOPEN -BOOL TRUE
...and the following will turn off the autoplay feature:
DEFAULTS DELETE COM.APPLE.QUICKTIMEPLAYERX MGPLAYMOVIEONOPEN
Hide the Controller Bar and Title Bar
QuickTime Player hides the controller bar and title bar whenever the mouse
leaves the program window, but as soon as the cursor enters again, both
become visible. The following setting hides them permanently, although they'll
still be visible when QuickTime Player first starts. The first time you move
the cursor outside the program window, they'll permanently disappear.
Essentially this turns QuickTime Player into nothing more than a borderless
movie frame, without even a progress display, and you'll have to start/stop
the movie using keyboard shortcuts, as described in Tip 73, Control QuickTime
Player Using Keys , on page 81 .
The command to activate this feature is as follows:
DEFAULTS WRITE COM.APPLE.QUICKTIMEPLAYERX MGUIVISIBILITYNEVERAUTOSHOW -BOOL
TRUE
