Apparently the shutter speed and the vibration of the strings on the double bass are sufficiently close to each other to create the interesting interference pattern seen in the video. Keeping in mind that the lowest notes in the double bass are below 100 Hz, the shutter wouldn’t have to very fast to exhibit this phenomenon.
