screenrecord.sh examples

Create a screen recording called demo.mp4:
  ./screenrecord.sh -n demo

Create a high quality screen recording called demo.mp4:
  ./screenrecord.sh -n demo -h

Create a high quality screen recording called demo.mp4 and automatically open it when done recording:
  ./screenrecord.sh -n demo -h o
