The storyboard

One take stops at 30 seconds.

That is a model's ceiling, not a setting: the longest single generation in the catalog ends there. A storyboard is how a video goes past it: this one runs 32 seconds as a finished explainer, cut into 7 scenes that were each generated on their own.

32s total

  1. A clay office cubicle: Derek slumped at his desk with both hands round an oversized mug, the monitor glowing weakly on his face.15s

    Scene 1: It is not the coffee

    Your coffee stopped working. It's not the coffee.

  2. Grey-brown clay sludge seeping out of a crack high in a cave wall and running down it in heavy lobes.24s

    Scene 2: The sludge

    Every hour you're awake, your brain makes adenosine.

  3. A row of coin-sized sockets down a clay cave wall, three of them packed with sludge and burning amber from inside.35s

    Scene 3: Every one it fills

    It fills little sockets. Each one it lights makes you sleepier.

  4. The impostor, a small cream clay figure in a badly fitted sludge costume, standing alone in a pool of amber light.44s

    Scene 4: Caffeine is a fake

    Caffeine doesn't remove it. Caffeine is a fake.

  5. The impostor wedged into a socket that stays dark and cold, with the sludge heaped up behind it, blocked.55s

    Scene 5: The same shape

    Same shape. It plugs the socket without lighting it.

  6. A heavy clay door bowed outward in its cracked frame, sludge squeezing through every seam around it.65s

    Scene 6: Right behind the door

    The adenosine keeps piling up, right behind the door.

  7. The cubicle again, the cave door burst wide open behind Derek and the sludge pouring through it.74s

    Scene 7: That's the crash

    Caffeine wears off. The door opens. That's the crash.

One card

Redo one scene. The other six never move.

A scene is a row of its own, with its own start frame, its own motion prompt and its own take. Open the one that came back wrong, change the prompt, run it again, and nothing else in the video is touched or re-charged.

Motion prompt
Camera: very slow push in on the socket over the whole shot. Action: the impostor wriggles and settles deeper into the socket, and the socket stays dark and cold the whole time…

What the redo costs
75

The start frame is already made, so a redo pays for the clip alone.

The finished cut

And here is what came out.

The same seven scenes, joined, with the voice-over and the music bed under them. Nothing on this page is a mock-up of it: the strip above is its own start frames, and the card is its fifth scene.
