I was today years old when I fiinally realized that the low quality setting in the video stream is actually super useful.
Sure, it is not much to look at, but when you are sampling the time line, to see if anything interesting happened in your favorite realm, or to find the juciest bit of a sex act, low quality is ultra fast. You can click on various points in the time line in quick succession because the footage loads almost instantly. Try it out.
