screencasting

After days trying to figure out how to make a good screencast using ubuntu, I finally got it--use ffmpeg!

To capture full screen, the cli (command line input) is-- ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1440x898 -i :0.0+0,1 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 output.mkv

To find out specs for screen capture, the cli is: “xwinifo”

ffmpeg comes in the default ubuntu package, or you can find it in your synaptic package manager.

Next step: learn how to use cinelerra.
