# MiniMax H3 threading prompt: keep one cord continuous through a fixed eyelet

Advance a cord that is already partly threaded through one large eyelet. Judge the relationship between the near segment, the covered passage and the emerging end.

Original synthetic practice still, not a generated result. No model run has been performed.

## Generator

Use MiniMax H3 base image-to-video. Turn on Add end frame to expose First Frame, upload first-frame.png only, and leave Last Frame empty. Fast requires a pair and is not covered. Choose only options offered by the current interface; opening it does not submit.

## Starting state

A thick orange cord approaches a fixed teal eyelet from the lower left and a short end emerges at the upper right. The hole is large and empty enough for the crossing to remain visible; no knot or hand is present.

Keep the eyelet center and rim fixed. At both edges of the hole, the visible cord should meet the same passage. Do not infer the exact shape of the hidden segment from pixels that are not visible.

## Steps

1. Identify the two visible segments and the one hole they share. Use a partly threaded starting state to avoid asking the model to invent an entire hidden threading procedure.
2. Request a small feed and stop with cord visible on both sides. Do not combine threading with tying a knot or looping around a second object.
3. Inspect frames around the hole edges. A long emerged end is insufficient if it appears from the solid mount or the near segment stays completely unchanged.

## Acceptance

- The eyelet center, rim and mount remain fixed.
- Both visible cord segments meet the same hole without passing through its solid rim.
- The emerging side grows while the near visible segment feeds toward the hole.
- One continuous cord remains visible on both sides in the final hold.

## Limits

Only visible routing continuity is assessed. The exercise does not prove tensile strength, friction or the hidden cord's exact three-dimensional path.
