The better the quality of video and audio, the bigger will be the size of recorded file. You can adjust video and audio quality (and consequently size of the output video file) by adjusting the slider near the top right of this window. (Tip - Video Quality of 50% is good enough for most purposes and will keep file size lower).

As a teacher, one of the ways you can make resources is to use recordmydesktop to create a video file by combining your voice narration with a set of slides or pictures or a video (or a combination of these) on your screen. You can simply play a slideshow of your slide presentations or images in your folder, or a video, recording these through recordmydeskop and providing the audio with your explanation / lecture. This can be used to create lessons for reinforcing learning or for students who have missed a class, to catch up.
