Install ImageMagick

brew install ImageMagick

Pull specific region of frames from video file w/ ffmpeg

ffmpeg -ss 14:55 -i video.mkv -t 5 -s 480x270 -f image2 %04d.png

  • -ss 14:55 gives the timestamp where I want FFmpeg to start, as a duration string.
  • -t 5 says how much I want FFmpeg to decode, using the same duration syntax as for -ss.
  • -s 480x270 tells FFmpeg to resize the video output to 480 by 270 pixels.
  • -f image2 selects the output format, a series of still images — make sure there are leading zeros in filename.

Enable HiDPI mode in Mountain Lion w/o Quartz Debug
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES;
sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled;
// by the way, you need to logout and log back in for this to take effect. Or at least that's what
// Quartz Debug says. Who knows, maybe it's lying?
// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging
// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.
