Stop a moving cup and inspect the liquid that keeps moving

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

1. Task and boundary

Move a partly filled clear cup a short distance across the table, stop it, and let the liquid surface continue moving before settling. Keep the cup upright throughout. The important interval begins after the cup stops, when the free surface still changes height against its stationary walls.

This original scene is untested. Use a modest movement and substantial empty space below the rim. Exclude spilling, exact acceleration, simulated damping values and a liquid surface pasted rigidly to the moving vessel.

2. Authorized first frame

Use a photograph or accurate drawing you own or have permission to use. Show a clear cup partly filled with plain water on a level table. The original hand holds its handle, and one fixed background mark sits beside the intended stopping position.

Choose a side view exposing both sides of the free surface. Leave travel room and rim clearance. Keep the cup base in contact with the table, with no tilt or lifted base already present in the first frame.

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 a partly filled upright clear cup on a level table, held by the original hand at its handle. Lock the camera and background mark. Move the cup a short distance to the right along the table, then stop it at the mark without tilting. After the cup stops, let the water surface continue a small side-to-side slosh relative to the now stationary walls. Show the surface height changing at opposite walls, then gradually becoming calmer and more level. Keep the water connected and below the rim, and preserve the cup base, handle and hand grip. Hold the final upright cup with a calmer surface. No spill, new liquid, moving background, rigid water block, second push, camera tracking, cut or measured damping claim.

1. Establish, first fifth: locate the initial free surface and fixed stopping reference.
2. Move and stop, middle three fifths: separate cup travel from the later motion of water against stationary walls.
3. Settle, final fifth: hold the cup while the visible surface excursions become smaller.

5. Inspect the output

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

• The cup translates along the table without tipping.
• The background mark stays fixed while the cup approaches it.
• Water continues moving relative to the walls after cup motion ends.
• The surface remains one connected boundary with no separate hovering slab.
• The ending surface is calmer while the cup remains at its new position.
• If the surface is hidden behind the hand, mark relative liquid motion inconclusive.

6. Fix one failure

• The water moves as a solid block: request changing contact heights at the two walls.
• The cup rocks instead of stopping: anchor its base and upright axis after translation.
• The liquid spills: reduce travel and increase empty rim space in the input.
• The background follows: preserve the original reference mark and fixed camera.
• Sloshing never settles: request fewer, smaller visible excursions before the final hold.

7. Ending and limits

Finish with the cup stationary at the new location and its connected liquid surface visibly calmer.

No H3 generation, slosh-frequency measurement or damping simulation is supplied. Suggested phases are visual checks, not a prediction of how quickly a real cup of water will settle.

The pouring task changes how much liquid occupies a vessel. Here the amount stays visually consistent and the motion of its free surface continues after container travel ends.
