You may want to add background music to an audio recording. It is easy to do this with Audacity. You will add a second track, to which you will add the background music. We can add as many tracks as we want, with one audio file per track.

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).

We need to wait till the export is completed, to get the output file. If we close the process before, we will lose the output file. The output file will be saved in your "Home" folder by default, with .OGV format. The file will usually have a name like ‘out.ogv’, however you can use the ‘save as’ button on the RecordMyDesktop screen to give a file name.

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 slide show of your slide presentations or images in your folder, or a video, recording these through RecordMyDesktop 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.
