Let suspended sediment settle beneath a clearer upper layer

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

1. Task and boundary

Show suspended particles gradually leaving the upper part of a transparent vessel and collecting near its bottom. The liquid stays inside the vessel throughout. The useful sequence connects downward particle paths, a growing bottom deposit and an increasingly readable upper region without replacing the whole liquid with a clear image.

Use a qualitative, time-compressed settling illustration. Exclude a sieve, drain, stirring paddle or second vessel. Do not imply that every particle must settle or that the remaining liquid becomes chemically pure.

2. Authorized first frame

Prepare a photograph or drawing you own or have permission to use. Choose a narrow transparent vessel with visible bottom, sidewalls and liquid surface. Start with sparse, readable suspended flecks throughout the lower and middle liquid, plus several higher flecks and a nearly bare bottom.

Keep a dark background feature visible through one clear upper corner. Use enough contrast to follow selected particles without making the vessel opaque. No hand or moving support is needed.

3. Use the generator

Open the image-to-video generator in a mode accepting your authorized first frame. Paste the prompt and review settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Use my authorized first frame of a stationary transparent vessel containing water and suspended sediment. Fix the camera, vessel, background and liquid surface. Show selected original particles drifting downward through the water and joining a visible deposit on the bottom. As fewer particles remain high in the vessel, let the upper liquid become easier to see through. Build this change progressively from individual paths and bottom accumulation, not a sweeping transparency wipe. Retain a few faint suspended flecks. Do not drain liquid, add a filter, pour, stir, raise the deposit as one rigid slab or make particles vanish halfway down. Finish with a clearer upper region above the collected sediment.

1. Opening fifth: identify the upper flecks, exposed bottom and stable liquid surface.
2. Middle three fifths: follow several downward paths and compare the developing deposit with the clearing upper region.
3. Final fifth: hold the separated appearance. Timing fractions are editorial guidance, not a settling-speed prediction.

5. Inspect the output

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

• The liquid surface and vessel corners remain fixed as the upper region clears.
• Several particles have readable downward paths before reaching the bottom.
• Bottom accumulation grows where those paths end, without lifting an existing block.
• Upper clarity improves progressively rather than changing in one global dissolve.
• Some unresolved fine flecks may remain; complete transparency is not required.
• If particles disappear behind glare or an opaque cloud, their destination is inconclusive, even when the final deposit looks plausible.

6. Fix one failure

• Everything fades at once: reduce cloud density and request individually readable paths.
• Liquid level falls: explicitly preserve the surface and remove draining language.
• Deposit appears instantly: request a smaller amount of settling with visible arrivals.
• Particles travel upward: simplify the scene and restate downward travel toward the existing bottom.

7. Ending and limits

End with liquid still present above a visible deposit and a less crowded upper region.

No H3 run or physical trial is supplied. This review does not determine particle density, purity, sediment mass or settling time. A stylized clearing boundary is not a measured separation front, and generation success is unverified.

The sieve task separates classes through fixed apertures. Here particles remain in one liquid column and collect at its base without an aperture. Merely choosing another sediment color would preserve this same task.
