Also, a quick look at the 35mm film strips on the poster reveals that the film strips have no soundtrack. Indeed, the picture goes straight to the perfs on either side, meaning an audio player would have to be completely turned off to accommodate.
A monochromatic band is usually located between the image and the perfs on the right side of the image. Monochrome tracks can look a few ways. Some single lines look like an alternating grayscale band. These are called variable density tracks. Other mono tracks, optical tracks, have “More Tonal Scales” that look white. There can be one, two or even five single tracks. If all the squares were the same, the audience would hear the same audio information coming from each speaker in the theater. If the ticks are different, it could be a Dolby stereo print, with different information that separates the audio channels.
“The Fabelmans” obviously doesn’t handle digital tracks, otherwise one might have to find a vague Dolby track in the middle of the perfs, one that looks for “Morse code” for DTS (remember DTS? People who played their audio from compact discs). Or, in some cases, the sound may appear as two digital tracks on the outer edge of the film. That’s for SDDS. Remember SDDS?.
Let’s just hope that someone fixes these nasty mistakes before the movie comes out, otherwise no one will be able to take the movie seriously.
