title: While ffmpeg is recording, I want it to create a smaller and lower quality video
body: <p>Currently I am using this...</p>
  <pre><code>ffmpeg -video_size 1920x1080 -framerate 1 -f x11grab -i :0.0+0,0 -f pulse -ac 2 -i default -t 00:00:10 Output.mkv
  </code></pre>
  <p>While ffmpeg is recording a video, I want it to significantly reduce both the <strong>size</strong> and <strong>quality</strong> compared to the ffmpeg command above.</p>
  <p>In case you are curious, I am recording brief quality assurance videos to ensure a simple little web scraper I wrote in Python is scraping data properly (specifically, that it is clicking on a particular button, at a particular time, on a particular web page). My Python script triggers the command above to start recording my screen a few seconds before my Python script is supposed to click on that button.</p>
  <p>Of course, to verify a button on a web page had been clicked on, low quality video resolution would normally suffice.</p>
