Squeeze a clothespin, then release its jaws onto a card

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

1. Task and boundary

Squeeze the tails of one spring clothespin to open its jaws, move the open jaws around a stationary card edge, then release the tails. End with the original clip resting on the card and the operating fingers clear, so the released grip is visible.

This is an original, untested shot plan for a conventional two-arm clothespin. Exclude a motorized clamp, a flexible snap hook and adhesive attachment. It reviews opposite jaw motion and the released contact state, without claiming grip strength.

2. Authorized first frame

Use a photograph or accurate drawing you own or have permission to use. Show the clip side-on, with its spring joint visible and one hand already pinching the two tail ends. Place a plain upright card edge just beyond the closed jaws; its lower portion is held by a fixed support.

Keep fingers behind the spring and show both jaw tips. Leave a small approach gap between clip and card. A contrasting background should make the card thickness readable without adding printed marks or hiding the lower jaw.

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 spring clothespin beside a fixed upright card, with the original hand holding its tails. Lock the side camera, lighting, card and support. Squeeze the original tails toward each other so the two jaws rotate apart around the same visible spring joint. Keep the two arms rigid and preserve the spring connection. While the jaws are open, move the clip a short distance so the card edge lies between both jaw tips. Release the tails gradually so the jaws close onto opposite faces of the same card. Then move the operating fingers clear without pulling the clip away. End with the original clothespin resting on the card edge, its spring and both contacts readable. No jaws bending like rubber, merged arms, extra clip, adhesive, card piercing, camera motion, cut or second clamp cycle.

Open, first third: compare tail closure with jaw separation around the spring.
Position, middle third: pass the card edge between the already open jaws without clipping through it.
Release, final third: close onto both card faces and withdraw the operating fingers for inspection.

5. Inspect the output

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

Tail ends move closer while jaw tips separate around the original joint.
Both clip arms and the spring remain connected without changing lengths.
The jaws are open before the card enters their gap.
Closing places one jaw on each card face without piercing the sheet.
The clip stays on the card after the fingers visibly clear it.
If one jaw is hidden throughout release, mark two-sided contact inconclusive.

6. Fix one failure

The whole clip bends: retain two rigid arms and localize rotation at the spring joint.
The card passes through closed jaws: separate opening and approach into successive beats.
Both jaws land on one face: use a clearer side view with visible card thickness.
The clip follows the withdrawing hand: add a brief clear-finger ending before the shot ends.
The spring disappears: keep the grip behind it and simplify nearby background detail.

7. Ending and limits

Finish with the same clothespin gripping the supported card and the operating fingers clear.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 run, spring-force measurement, pull-out test or real fastening recommendation is supplied. Staying in place within a proposed clip does not establish load capacity.

The snap-latch task bends a hook past a shoulder. Here two rigid arms pivot oppositely and a released spring closes two contacts around a sheet. Changing clip material alone would not create a new task.
