# MiniMax H3 loose-knot prompt: tighten without swapping the crossings

Reduce an already formed loose knot while keeping the same rope route. This is not a request to tie a new knot from straight ends, and it is not a real-world tying or load-bearing lesson.

**Original practice illustrations and an untested method.** No H3 task has been submitted and no generated result is included.

## 1. Establish the authored starting state

The input is a flat drawing of one continuous ochre rope. Its two endpoints have distinct teal and coral caps. Three projected crossings have explicit front/back occlusion, generated from one open three-dimensional parameter path; rope-path.json records the original points and which branch is above at each crossing. The drawing is an authored loose single-knot diagram, not a reconstructed physical rope or a guarantee about hidden three-dimensional material.

## 2. Assign the moving and fixed roles

Start at a colored end cap and trace the same strand through all three crossings to the other cap. An underpass is hidden behind a different part of the same strand, not a cut end. The supplied guide circles the crossing locations only; do not upload it as another frame.

1. Before using the prompt, trace from the coral cap to the teal cap and check the three over-under relationships against the separate guide. If you redraw the source and cannot follow one continuous route, stop and fix the drawing first.
2. Move the original two ends a small distance outward along their existing upper-left and upper-right exit directions. Ask for the current knot body to become more compact, rather than creating an extra loop.
3. For a future clip, pause at each crossing while the central body contracts. Compare which branch is in front; a smooth-looking final knot is insufficient if a strand passed through another in the middle.
4. Compare end lengths and the fixed canvas. Shortening the central knot should be accompanied by visible change along the free end sections, not a global camera zoom. Stop before making claims about tension, strength or a physically tight endpoint.

## 3. Prepare one manual generation attempt

Use the current **MiniMax H3 base image-to-video** controls. Under the currently documented site workflow, enable **Add end frame** to expose **First Frame**, upload only `S01-first-frame.png` there and leave **Last Frame** empty. This draft does not use Fast, which needs a paired input. Recheck the actual available controls and credit estimate before any manual submission; these files neither upload themselves nor start generation. SVG files and the separate review guide stay local as design/review materials. No duration, resolution or endpoint capability is promised by this method.

## 4. Use the complete original draft

```text
Use the supplied original loose single-knot illustration as the first frame. It contains one ochre rope with one teal end cap, one coral end cap and three already defined over-under crossings. Keep the camera and pale background fixed. Gently draw the existing ends a small distance outward along their current upper-left and upper-right exit directions. Let the same central knot become a little more compact as the free end sections extend. Keep both colored caps on the original endpoints and preserve the existing front/back order at every crossing. The rope stays one continuous strand: no cutting, solid pass-through, fused junction, exchanged crossing, extra knot or new rope. Do not untie it into a straight line or turn it into linked rings. Stop with the same slightly more compact knot and both ends visible. This is an untested visual continuity request, not a physical tying, tension or safety demonstration.

The copyable generator draft is the English version; the paired Chinese draft is included for review.

## 5. Inspect the actual result in sequence

Do not fill a pass from the input or from the intended ending. Enter observations only after examining actual result frames. The downloadable sheet has empty observation and result fields.

- Exactly two original colored end caps remain on the same continuous strand.
- Each original over-under crossing keeps its front/back order during motion.
- No visible branch cuts, fuses or passes through the solid rope at a crossing.
- The central knot becomes modestly more compact while free end sections visibly adjust.
- The canvas and camera stay fixed; whole-image scaling is not counted as tightening.
- The ending is the same single knot with two ends, not a new knot, chain, bag opening or straight cord.

## 6. Repair one failure without changing the task

- If an overpass becomes an underpass, keep the source and reduce only the tightening amount; inspect that crossing before changing the whole prompt.
- If the rope splits or fuses at a junction, restate only that each crossing is an occlusion of one strand, not a branching connection.
- If the whole image shrinks, remove zoom wording and preserve the background frame as a fixed comparison.
- If the knot unties or a second knot appears, change only the ending to a slightly compacted version of the existing knot. An ambiguous original drawing should be corrected instead of explained away.

## 7. Save the ending and choose the right next task

Keep a note for each of the three crossings and for both end caps. The supplied route is source geometry for review, not a measured path recovered from a generated clip.

No model task, real tying action, force estimate, load test or safety certification was performed. The geometry describes the authored illustration and cannot establish a usable real knot.

A fixed-eyelet task passes a cord through a separate rigid hole; a drawstring gathers fabric without a knot; a chain preserves adjacency among separate rigid rings. None supplies this one-strand self-crossing route.
