MiniMax H3 rolling-cylinder prompt: couple travel with rotation
Request one short roll of an original marked cylinder. Check its center, radial mark and floor contact together instead of confusing object motion with a camera slide.

MiniMax H3 rolling-cylinder prompt: couple travel with rotation
Move one cylinder a short distance to frame right while its marked end rotates clockwise. The useful distinction is between rolling, sliding and a camera tracking past a stationary product.
Original illustrated practice input; method not independently tested. No H3 generation or model output is supplied. A result, if you later generate one, still needs the checks below.
!Original illustrated practice input, not a model result
Read the starting input
The original illustration has a short teal cylinder resting on a horizontal surface. A light radial stripe on its circular end makes rotation visible; the floor line and two distant blocks provide fixed position references.
Track three things independently: the end-face center, the stripe's orientation and the lowest visible floor contact. A rotating stripe alone does not prove that the object traveled.
Set up the current generator
Select MiniMax H3 base in image-to-video. Enable Add end frame so the current interface exposes the First Frame slot. Upload only first-frame.png to First Frame and leave Last Frame empty. This is not the Fast workflow: Fast requires both frames. Select a duration and ratio actually offered by the interface; these notes promise no exact motion timing. Opening a generator does not submit a task. The SVG is a design/inspection source, not an upload instruction.

Copy the original prompt
Use the illustrated first frame. Fixed side camera, fixed floor and background blocks. The single teal cylinder rolls slowly a short distance toward frame right on its curved side. Its center moves right while the pale radial stripe on the visible end turns clockwise. Keep the cylinder's diameter and end-face identity stable. Its lowest edge remains in contact with the same flat floor; no bouncing, hovering, stretching or camera tracking. Slow down to a stop and hold at the new position. One roll, one continuous shot, no full revolution required.Work through one attempt
- Mark the starting center and stripe direction on a separate note. Leave visible floor ahead of the cylinder; a tight crop makes translation impossible to judge.
- Request a short roll and a settled ending before adding a push, an incline or collisions. The visible task is coupled motion, not a demonstration of a force applied by a hand.
- Compare the same floor landmarks at three pauses. If they move with the cylinder, you may be seeing a camera move instead of the intended object motion.
Inspect the result
Record an observation for each item in the blank sheet. The sheet starts with empty results: none is a pre-existing pass.
- The center travels right relative to the stationary floor landmarks.
- The stripe rotates clockwise while the end face remains a single stable shape.
- Floor contact remains visible; the object neither hovers nor changes diameter.
- Translation and rotation both stop in the ending hold.
Change one failure at a time
- Center moves but stripe stays upright: restate that the marked end rotates, and reduce travel.
- Stripe turns but center stays fixed: distinguish rolling from spinning in place.
- Background follows the object: remove tracking language and repeat the fixed-camera constraint.
Ending, limits and related tasks
The same cylinder rests farther right with a changed stripe angle, stable diameter and visible floor contact.
This is a qualitative rolling-continuity exercise. It does not certify friction, inertia, exact angular velocity or a no-slip distance equation.
The shoe-slide page keeps its object stationary and moves the camera; the watch page turns a hand around a fixed center; the drop page focuses on impact. Here both center travel and end-face rotation must be observed together.
