A quick and dirty way to make a screenshot of a DVD playing in DVD Player. Remember: when DVD Player is open, you can’t capture the screen with Grab. Command-Shift-3 and Command-Shift-4 both do not work when DVD Player is open. So:
- Put your DVD in your computer and open DVD Player (Applications -> DVD Player) if it does not open automatically. Fast forward to the frame you want to capture, or select the scene to start at. Pause.
- Open the Terminal (Applications -> Utilities -> Terminal). Type this, or copy / paste it right in the Terminal:
screencapture -i ~/Desktop/example.png
- Your mouse should turn into crosshairs. Now hit the space bar. Your mouse should now be a camera. Click the window the DVD is playing in. A file called “example.png” will appear on your desktop.
I guess this only works when you’re watching a DVD in windowed mode. But it’s better than nothing.
