Roll dough once: leave a flatter strip behind the pin

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

Roll one plain pin across a small dough mound. Follow the advancing contact region and the flatter, wider material left behind it. Stop after one pass, with part of the original mound still visible ahead of the pin for comparison.

This original plan is untested. Use soft unfilled dough and a plain rolling pin. Exclude recipes, food-safety claims, exact thickness targets and a perfectly rectangular finished sheet. The requested change is visible deformation under rolling contact.

2. Authorized first frame

Prepare a photograph or accurate drawing you own or have permission to use. Show a short thick dough mound on a plain board, with the pin resting across its near edge and the original hands on both handles. Include a small existing end-face mark that reveals rotation.

Use an oblique side view that shows the mound height, contact line and both side edges. Leave room behind the moving pin for the flattened material. Keep the board corners visible; avoid loose flour clouds or decorative toppings that hide the surface.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the prompt; check settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Start from my authorized image of one dough mound, a rolling pin at its near edge and the original hands on both handles. Lock the camera, lighting and board. Push the pin forward once so its barrel rolls over the dough rather than sliding without rotation. Keep the visible end mark turning with the original barrel. As the contact line advances, reduce the dough height locally and let the same material spread outward into a broader, flatter region behind the pin. Preserve connected dough edges; do not replace the mound with a finished sheet. Leave some original thickness visible ahead of the pin. Keep both handles, hands and barrel connected, with no changing pin diameter or extra fingers. Stop after a short pass and hold the pin still. The flattened region remains rather than immediately springing back. No return pass, cutting, flour burst, camera move, cut or lettering.

1. Establish, first fifth: identify the initial mound height, barrel mark and board anchors.
2. Roll, middle three fifths: compare early, middle and late contact positions and the material left behind.
3. Hold, final fifth: inspect the thinner region beside the remaining thicker portion after the pin stops.

5. Inspect the output

For each check, record a frame or time, observation and pass, fail or inconclusive judgment.

• The barrel both travels and rotates, retaining contact with the dough.
• Height reduction follows the moving contact region rather than appearing everywhere at once.
• The flattened region remains connected to the thicker material ahead.
• Side edges spread without duplicated dough, holes or disappearing material.
• After stopping, the pin and board stay steady and the flattened region persists.
• If the pin hides every thickness reference, mark flattening inconclusive rather than judging only the overhead outline.

6. Fix one failure

• The pin slides: retain an end-face mark and explicitly couple forward travel with barrel rotation.
• The entire mound becomes flat instantly: shorten the pass and preserve an untouched region ahead.
• Dough springs back: request persistent local flattening and remove elastic recovery language.
• The sheet gains holes: simplify the starting mound and keep one connected body.
• Hands hide the profile: lower the authorized camera angle and keep grips near the handles.

7. Ending and limits

Finish after one pass with a connected flatter region, remaining thicker dough and the same pin at rest.

No H3 generation, force measurement, recipe validation or dimensional accuracy is supplied. Visible spreading cannot establish material volume or cooking suitability.

The rolling-cylinder task preserves a rigid floor; the sponge task ends in recovery. Here moving rolling contact leaves a persistent deformed material region. A different pin color would remain this task.
