A record is a sound track, which a movie encapsulates.
A _____ is a _________, which a photograph encapsulates.
Pixel? Not really, a movie has (mostly) one sound track, but a picture has many pixels, and pixels appeal to only one sense.
Monochrome image? That supposes the picture is color, encapsulating three or more different color layers, plus same sensory problem.
Intensity? Pretty much the same as a pixel.
The challenge is, pixels or color "panes" in aggregate completely comprise a picture, whereas sound tracks cannot completely comprise a movie.
Also, a record can be appreciated by only one sensing modality, while a movie appeals to two sensing modalities. Or, in a theater, three (remember that opening scene in the first star wars where the cruiser fills the screen and the sound is so intense you can feel the vibration?).
Maybe we have to discount the sensory dimensions, because how can you go below 1 sensing modality?
HEARING/SIGHT is to HEARING as SIGHT is to NOTHINGNESS. Ah, maybe I see how Carl came to "Singularity."
Back to the larger discussion, ...
Video is comprised of individual pictures. Humans can perceive pictures one at a time, although we can extract a different kind of information from a time sequence of images presented at a rate compatible with our capabilities. Video stuttering is a nuisance, but we can still perceive most of the intended information because we can perceive each primitive, a photograph.
Sound is somewhat different in what constitutes a primitive. English is said to be comprised of 50 or so fundamental phonic elements. If speech were presented in these primatives, even if presented irregularly in time, we could probably perceive the intended information. For example, when the kids say something like "Daddy how do you spell 'that?'" I slowly phonetically say "Thhh", .... "aaaAAA!" ..... "t" and they (mostly) understand. However, when speech is arbitrarily chopped up and presented at varying randomized rates, in pieces, our processing is challenged to grasp those fundamental phoenetic elements, because the random pieces are not presented in these fundamental perceivable quantities.
