Press a bag seal closed from one end to the other

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

1. Task and boundary

Close one plain press-seal bag by pinching along its existing mouth profiles from left to right. Keep a short open section ahead of the fingers and a joined section behind them readable. Finish with the mouth closed along the inspected length and the fingers lifted away.

This original plan is untested. Use a simple slider-free press-seal bag with two continuous matching profiles. Exclude a toothed zipper, heat sealing, adhesive tape and leakproofness claims. A visibly joined seam does not certify an airtight or food-safe seal.

2. Authorized first frame

Prepare a photograph or accurate drawing you own or have permission to use. Show an empty plain bag with its mouth open and both profiles exposed. The leftmost short section is already aligned between the original thumb and finger; the remaining mouth stays separated.

Use a close oblique view that reveals both lips rather than flattening them into one line. Support the bag on a plain table and keep its lower corners visible. Leave enough room for the fingers to travel across the opening without hiding the entire seam.

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 empty plain press-seal bag with two exposed mouth profiles and the original thumb and finger aligned at its left end. Lock the camera, lighting and table. Pinch the two matching profiles together, then move the same pinch slowly from left to right along the existing mouth. Keep a visibly open gap just ahead of the fingers and a continuous joined seam behind them. The closure front follows direct finger pressure; do not invent a slider, zipper teeth, heat tool or adhesive. Preserve both original bag walls, mouth edges and lower corners. Allow small local wrinkles near the pinch while the bag stays supported. Complete one short closure pass, lift the fingers clear and hold the joined mouth visible. No automatic closure far ahead of contact, torn plastic, merged hand, camera movement, cut or reopening cycle.

1. Establish, first fifth: locate the aligned starting section and the still-separated mouth ahead.
2. Press, middle three fifths: compare early, middle and late closure fronts against the moving pinch.
3. Inspect, final fifth: lift the fingers and keep the joined seam visible along the completed length.

5. Inspect the output

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

• Both original profiles are visible ahead of the fingers before they meet.
• The joined region grows behind the pinch rather than closing remotely ahead of it.
• Bag walls and lower corners retain identity while local wrinkles follow pressure.
• No slider, teeth or adhesive appears to substitute for direct profile pressing.
• The completed mouth remains joined after the fingers lift away.
• If the view hides the two lips or the finished seam, mark closure continuity inconclusive.

6. Fix one failure

• The whole mouth closes at once: shorten the inspected length and preserve an open gap ahead.
• A zipper slider appears: specify slider-free continuous profiles and direct pinching contact.
• The bag melts into one sheet: preserve two separate walls below the joined mouth.
• Fingers hide every transition: revise the authorized angle and expose more seam behind the grip.
• The seam opens after release: add a clear final observation and remove reopening language.

7. Ending and limits

Finish with the original bag mouth joined along the completed pass and the fingers visibly clear.

No H3 output, leak test, sealing-force measurement or storage recommendation is supplied. The method checks visible closure only, without proving hidden profile engagement everywhere.

The zipper task follows a pinched pull and a traveling slider. This task has no slider: direct pressure joins continuous profiles beneath a moving finger contact. Different bag contents would not make a new task.
