I had some fun with this one.

There were a bunch of parts: I had to figure out how to record video, guitar audio track and vocal audio track at the same time (but separately); how to mix audio and video together (iMovie); and then deal with an annoying mistake that was buried in the video (I forgot to hide my computer screen).

To deal with that last one I played with Crop Filters and Color Correction in iMovie; also in the end I cropped out the offending computer screen. The effect is that the candlelight I recorded by makes the stylized face dance and move, and you can see my face and my guitar moving around behind the microphone.

I think the result is cool: https://youtu.be/YAyKJ0NW7Sw
