This is one of the only addons that AUTOMATICALLY captures video streams at the "source level", eliminating the need to fuss with capture areas, window sizing or frames to record just the video. It's not a screen recorder, per se, so the user can surf the net while video capture continues in the background. The problem is, I've noticed significant 3d noise ("grainy" picture) when playing back recorded videos. It's not a hardware shortcoming. Also, there's no toolbar button to toggle recording. The user does need to be on the video page to start or stop recording. However, once the "stop" button is clicked, the video is downloaded without any further user interaction, which is super, super handy.
