> My biggest gripe here is that I find it incredibly distracting when videos of string players do not sync to the video to the sound they produced. You can easily notice it when a single violinist changes bow direction and the sound doesn't change. In a study and art piece about synchronization, syncing video to audio is pretty crucial!

Could this have to do with the structure of the experiment? Since they’re playing “together” (physically) but are hearing each other play on a delay I would imagine only one player in the video could sync with the audio?
