# Run FFmpeg x11grab to a pre-set resolution of 1280x800 on monitor 1 in a separate terminal window to allow the main recording below to start simultaneously AND to be finished separately.  (If you run them as simultaneous processes you basically have to killall ffmpeg to make it stop, thereby losing all of your recording)

gnome-terminal -x ffmpeg -f x11grab -r 30 -s 1280x800 -i :0.0 -b 1000k ~/Videos/Screencasts/x11grab_$(date +%F_%A_at_%H:%M:%S).mkv

# Run FFmpeg to record from the system-defined audio-input (e.g. microphone) and from the primary webcam (/dev/video0) at a resolution of 1280x800.  Unfortunately the frame rate gets set to 10 fps rather than 30, I'm not sure how to change it.  But it does work.
