Press one staple through two sheets and show its folded legs

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

1. Task and boundary

Join two stationary paper sheets with one visible U-shaped staple. The task has two linked events: its legs pass through both sheets, then the anvil turns the projecting ends inward. A closed stapler handle alone proves neither. Use an explanatory cutaway to keep the fastener readable instead of asking an opaque desktop product to reveal its hidden interior.

This untested visual brief uses a simplified stapler with the selected staple already beneath its driver. Omit the magazine feed, spare staples and paper loading. The drawing must preserve a plausible driver, two leg paths and an anvil beneath them. It is a visual sequencing exercise, not a manufacturing drawing or a claim about staple strength.

2. Authorized first frame

Prepare an accurate schematic you own or have permission to use. Show a fixed stapler base, two aligned thin sheets, an anvil with inward-curving grooves, one U-shaped staple above the sheets and the driver above its crown. Choose a cutaway plane through both staple legs, with the near housing absent from the start.

Keep a narrow visible gap under the paper except where the anvil supports the working region. Use two different paper-edge tones so passage through both layers can be checked. The original hand rests on the upper lever without obscuring the driver. Do not add a separate after-view or an inset that could be mistaken for a second staple.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the complete prompt, check the available settings and cost estimate, then submit only when ready. This page supplies text; it does not upload an image or start a generation.

4. Prompt and timing

Use my authorized open cutaway drawing of a stapler with one original U-shaped staple under its driver, two thin paper sheets and a fixed grooved anvil. Hold the camera, base, anvil and paper edges still. The existing hand presses the upper lever once. Let the driver descend onto the staple crown and push both original legs down through both paper layers. As the projecting tips meet the anvil grooves, bend those tips inward under the sheets while the crown approaches the top sheet. Keep one continuous metal fastener: its crown stays above the paper and its bent legs remain below. Release the lever and lift the driver away, leaving the same staple seated across both sheets. Keep the cutaway open and show the final inward-folded legs. No extra staple, automatic reload, paper tear, disappearing fastener, whole-sheet movement, cut or x-ray overlay.

Opening: identify one staple, both paper layers, the driver and the two anvil grooves.
Middle: inspect penetration before the projecting tips turn inward at their contact with the anvil.
Ending: compare the seated crown and two bent legs after the driver withdraws.

These beats are author suggestions, not exact model timing guarantees. Adapt their proportions to the clip length actually available.

5. Inspect the output

After inspecting your own output, record a time or frame, visible observation and pass, fail or inconclusive judgment for each condition. A convincing ending alone does not verify the preceding action.

One original staple is present throughout; no replacement appears below the paper.
Both legs pass through both original sheets before forming the final clinch.
The bent region grows from tips that contact the anvil grooves.
The crown stays on top while the leg ends finish underneath.
The driver separates on release and the staple remains with the sheets.
If either leg or a paper layer is hidden, mark the corresponding clinch check inconclusive.

6. Fix one failure

The handle closes but the staple does not move: simplify the cutaway around the driver contact.
Bent legs appear before penetration: name the two events in order and reduce lever speed.
The staple becomes two separate hooks: preserve its connecting crown throughout.
Paper follows the rising driver: retain the sheets on the base and separate driver release from fastener retention.
A new staple loads immediately: exclude the magazine and stop after the first release.

7. Ending and limits

Finish with two unchanged sheet edges joined by one staple, its crown above and folded legs below, while the driver has lifted clear.

No generated take, fastening experiment or load rating is supplied. The sequence can be judged only where the cutaway shows contact. It cannot verify a real tool’s internal travel, paper damage or joint strength.

The scissor task removes a paper tip. The snap-latch task retains an elastic hook behind a shoulder. This task adds one metal fastener and permanently folds its two projecting ends beneath two layers.
