# Short zipper pull: preserve the pinch and the moving seam

Create one short zipper closure on a stationary pouch with a visible pinch throughout. The original illustration supports a planning exercise; this is not an independently tested H3 hand-contact result.

## Package and evidence

The first-frame SVG is original artwork authored for this task. The PNG is the raster upload derivative prepared during integration. Neither image is a model output. The illustration has no teaching text or arrows baked into the input.

Files: `first-frame.svg`, `first-frame.png`, `brief.en.json`, `brief.zh.json`, `checks.csv`, `README.en.md`, `README.zh.md`. The CSV result fields are intentionally blank; fill them from a clip you actually inspect.

## Prepare

1. Use the supplied pouch image or a permitted close-up in which the slider, pull tab, thumb and index finger can be distinguished. Avoid a hand covering the slider entirely.
2. Start with a zipper that is closed on the left of the slider and open on its right. This gives the short rightward closure a visible seam transition.
3. Keep the pouch supported on a surface and the camera fixed. Fabric deformation, a moving camera and a long pull would make contact failures harder to locate.
4. Limit the action to a small segment of track. Confirm the actual zipper direction on your own product rather than copying a screen direction that closes a different zipper.

## Copyable prompt

```text
Use the uploaded close-up as the start. The pouch remains supported and still on the table. The visible thumb and index finger keep a gentle pinch on the same zipper pull tab. Together the hand, tab and single slider move slowly a short distance to the right along the horizontal track, closing the small section immediately behind the slider. The two tooth rows join progressively at the slider; the remaining opening stays ahead of it. Keep the pinch visible, the tab connected and the pouch outline stable. Stop with the fingers still holding the tab. Fixed camera, no release and regrasp, no second hand, no long fabric stretch.
```

## Run and inspect

1. **Verify the seam direction.** Read the joined teeth on the left and separated rows on the right in the starting image. If your source is reversed, change the direction consistently before asking for closure.
2. **Keep one contact pair.** Name the thumb/index pinch on the same tab as the contact. Do not request picking up the tab first when the source already begins in a grasp; that adds a new contact transition.
3. **Track slider and tooth boundary.** Pause just after movement begins and near the stop. The joined/open boundary should follow the slider, with joined teeth left behind rather than a painted line simply sliding over the pouch.
4. **Check the held ending.** Stop while the fingers still grip the tab. Compare finger count, tab shape and pouch outline with the start, then change only the failed contact or travel variable on the next attempt.

## Acceptance

- A single slider and one attached pull tab remain visible.
- Thumb and index finger keep contact with the same tab throughout the pull.
- The hand does not pass through the tab or zipper track.
- The slider follows the horizontal track for one short rightward move.
- The tooth rows join behind the slider rather than opening in the closure direction.
- The pouch stays supported without being dragged or stretched into a new shape.
- The end holds with the pinch intact and without an extra hand or release-and-regrasp.

## Change one variable per retry

- **Fingers lose the tab then grab it again:** Change only the contact phrase to a continuous pinch from the existing start; remove any pick-up or regrasp instruction.
- **The slider moves but the seam does not change:** Change only the seam description to rows joining immediately behind the slider; inspect that local boundary before altering speed.
- **The pouch stretches after the hand:** Reduce only the pull distance and recheck the pouch-to-table relationship.
- **Extra fingers cover the contact:** Change only the source crop or hand pose so the thumb/index pinch is unobstructed; retain the short action for comparison.

## Ending

Finish on the short closed segment with fingers still holding the tab. Save close crops of the pinch and tooth boundary at start, mid-pull and hold; both must pass.

- `/blog/product-shape-consistency-video`: This input and checklist isolate the slider, pinch contact and tooth transition; the broad product article does not provide a zipper contact task.
- `/blog/image-to-video-motion-prompts`: This is a bounded contact-maintenance exercise with visible zipper teeth, rather than a general explanation of first-frame motion.
