Pull one stitch through: let the needle lead and the underside loop shrink

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

1. Task and boundary

This shot finishes one stitch that has already begun. The needle point and most of its shaft are above the cloth, while the eye and its thread remain just below. A loose thread arc hangs beneath the cloth between the preceding stitch point and the needle eye. Pulling the needle upward brings the eye through the existing puncture; continued thread travel reduces that same underside arc until it rests against the cloth. Do not skip from a loose loop to a finished-looking seam.

The action starts after the needle has pierced the fabric. It contains one pull-through, with no new puncture, knot, second stitch or cut thread. The preceding stitch keeps one end of the visible working segment anchored; this page does not ask the model to invent that anchor during the shot. The endpoint is a seated stitch segment and a needle clear above the cloth, not a completed or strength-tested seam.

2. Authorized first frame

Use an original diagram or an image you are authorized to adapt. A clear side-oblique schematic is preferable to a photograph that hides the underside. Show one thin cloth strip, the preceding stitch point on the left, the current puncture on the right, and one needle pointing upward through the right puncture. Keep the eye just below the cloth and show the same thread running from the established left stitch into a slack underside arc and through the needle eye.

Make the underside readable through the side view or an already present, clearly schematic edge cutaway. That cutaway must stay fixed; it is a viewing device, not a tear created by the action. Show enough of the preceding secured stitch to establish where the working arc begins. Leave room above for the whole needle and eye to emerge without cropping. Use contrasting thread and cloth colors, a plain background and large enough features to follow the eye, puncture and loop separately. If the input cannot show those relationships, simplify the drawing before requesting motion.

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 the supplied first frame. Keep the cloth strip, left preceding stitch and right existing puncture in place. One hand grips the exposed needle shaft above the cloth, leaving the point of passage and the needle eye visible. Pull that same needle steadily upward through the right puncture. Keep the thread continuous through its eye. First the remaining shaft and eye clear the cloth; as the attached thread is drawn through, the loose arc beneath the cloth becomes progressively smaller. Preserve its connection to the established left stitch and keep the moving thread passing through the same right puncture. Let the underside segment finally lie against the cloth between those two points, with only a small local settling movement. Stop the pull once the slack is taken up. Hold the needle and its exiting thread above the cloth. Do not create another hole, needle, loop, knot or stitch; do not move the punctures, tear the cloth, shorten thread by fading it away, or cut to the final pose. Keep the camera and light steady.

Opening: hold long enough to locate the left anchor, right puncture, needle eye below the cloth and the complete slack arc. The right puncture is already occupied by the emerging needle.
Middle: follow the eye across the cloth boundary and then the attached thread through that same opening. Watch the underside arc reduce continuously while the upper drawn-out segment becomes longer; these are connected parts of one thread.
Ending: stop when the underside stitch segment rests against the cloth and the needle is clear above it. Keep a short settled hold without beginning a return stroke, new puncture or knotting action.

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 needle retains its shaft, point and eye; the thread stays attached through the same eye as it crosses the cloth boundary.
The preceding stitch and current puncture stay in the same cloth locations, with no extra hole or migrating entry point.
The underside arc shrinks progressively as thread travels through the current puncture, rather than disappearing, changing into a new loop or snapping straight in one frame.
The visible upper thread segment lengthens while the underside slack is taken up, and the shared thread route remains continuous at the puncture and needle eye.
The final underside segment seats between the established stitch point and current puncture; the pull stops without a new stitch, large cloth distortion or an invented knot.
If the hand, fabric or blur hides the eye crossing or the shrinking underside arc, record inconclusive; a tidy final stitch alone does not verify the pull-through.

6. Fix one failure

If the loop vanishes instead of feeding through, reduce the pulling distance and emphasize the paired change: less slack underneath and more drawn thread above the same puncture.
If the thread detaches from the needle, use a clearer, larger eye in the authorized diagram and keep it visible until it passes the cloth. Avoid decorative thread textures that hide the connection.
If a second hole appears, state that piercing is already complete in the first frame. Keep the needle on the existing passage instead of asking it to search for a sewing position.
If the hand blocks the loop or eye, move the initial grip higher on the exposed shaft and widen the view. Do not replace the hidden event with a camera cut.
If tightening drags or tears the cloth, ask for less travel after the slack is removed and a small settling finish. Reinspect the entire route after changing one instruction.

7. Ending and limits

The ending contains one seated underside stitch segment and the same needle held above the cloth, joined to the exiting working thread. Keep the brief hold gentle: it supplies a visible endpoint, not evidence of seam strength, secure knotting or readiness for a later sewing operation.

Save your own generated result through the available result controls, together with the authorized input, exact prompt, settings and inspection notes.

No generated example, physical sewing test or measured thread tension is supplied. A single image may not encode hidden thread topology reliably, and a plausible texture can conceal a broken route. Treat any obscured connection as uncertain. Save your own result and observations; do not report the suggested timing or the intended motion as a measured outcome.

The fixed-eyelet threading task advances a cord through a stationary opening. This task adds a needle carrying the attached thread through cloth and a specific underside slack-to-seated-stitch change anchored by the preceding stitch. The shared continuity check is useful, but neither a free cord moving through an eyelet nor a tidy seam silhouette substitutes for this sequence.
