1. Play along to your iPod while recording the video.
2. Once the video is imported to your computer, import the original song you covered.
3. Synchronize your drumming and the song's audio so that they match. This is pretty hard, but you can use the audio waveforms to do it (or not).
4. Play around with the audio levels of the song.
