Bram Ruiter’s review published on Letterboxd :
A congregation of bubbles rapidly displace over the 16mm frame while a crackle fills the soundtrack. It’s not long before the crackle comes in the same rhythmic bursts as what we’re currently seeing. Before digital projection, the film projector would read the soundtrack (which was printed right next to the image) and send whatever was on there to the sound system. This was for the longest time the best way to keep image and sound in sync. But what if one would have the ‘sound-scanner’ read the image, instead of the soundtrack?
