that may sound like an ultra-dumb question, but i'm curious to see if there's any interpretation going on.
so, personal explanations welcome beyond the 'division of a play, film, novel, etc., representing a single episode.'
The simplest explanation that I can come up with is that a scene, in a motion picture (we're not talking about any other medium here) is sort of like a paragraph.
Not literally, because in prose one can have many paragraphs in what would be a single scene in a movie but rather in this sense.
A paragraph generally embodies a "single topic" -- it has a beginning, a middle, and an end -- and it generally is part of something larger such that it can often only be understood in terms of that larger unit -- a story, an essay, a novel.
They can be long or short, but generally there's an upper limit before you've exhausted that 'single topic" aspect which will naturally tend to break a paragraph apart. Same with a scene.
So you can have a scene that's the equivalent of a paragraph like this:
"From that chamber, and from that mansion, I fled aghast. The storm was still abroad in all its wrath as I found myself crossing the old causeway. Suddenly there shot along the path a wild light, and I turned to see whence a gleam so unusual could have issued; for the vast house and its shadows were alone behind me. The radiance was that of the full, setting, and blood-red moon, which now shone vividly through that once barely discernible fissure, of which I have before spoken as extending from the roof of the building, in a zigzag direction, to the base. While I gazed, this fissure rapidly widened—there came a fierce breath of the whirlwind—the entire orb of the satellite burst at once upon my sight—my brain reeled as I saw the mighty walls rushing asunder—there was a long tumultuous shouting sound like the voice of a thousand waters—and the deep and dank tarn at my feet closed sullenly and silently over the fragments of the “
House of Usher.”
Or, you can have a scene that's the equivalent of a paragraph like this:
"She was dead."
