Let a falling stream reach the wheel before it turns

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

1. Task and boundary

Show a narrow stream reaching the right side of an initially still waterwheel. The same wheel then begins turning clockwise around its fixed axle, carrying successive blades through the contact region. The inspection centers on the order of arrival and rotation, with water continuing past the blades into a tray.

Use one exposed wheel and a simple upper spout. Exclude gears, belts, hidden motors and an independent spinning texture. This is a qualitative contact-and-motion illustration, not a water-power demonstration or validated turbine design.

2. Authorized first frame

Prepare a frontal photograph or accurate drawing you own or are allowed to use. Show a small wheel with broad cup-like blades, its central axle and support, and a spout above the upper-right quadrant. A visible small gate initially closes the spout.

Leave the full gap from spout to wheel unobstructed and show a tray beneath. Mark one existing blade subtly so rotation can be followed. The right-side downward flow should have a clear route to the blades rather than passing behind the wheel.

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 one stationary waterwheel with a fixed central axle and a gated spout above its upper-right side. Lock the camera, support and tray. Lift the small gate once so a narrow stream emerges from the spout and crosses the visible gap. Only after water reaches the right-side blades, let the same wheel start rotating slowly clockwise as viewed. Track the original marked blade and show successive blades meeting the stream. Keep the axle fixed, the blade count unchanged and the water continuing downward into the tray. No premature spinning, motor, gear, belt, giant splash, wheel translation, cut or zoom. End with the stream continuing and the wheel turning gently.

1. Opening fifth: locate the closed gate, dry gap, axle and marked blade.
2. Middle three fifths: review gate opening, stream arrival and first wheel motion in order, then follow the marked blade.
3. Final fifth: show continued blade contacts under the same stream. These shares organize visibility, not a startup-time or speed prediction.

5. Inspect the output

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

• Water visibly crosses the spout-to-wheel gap before the wheel begins rotating.
• The marked blade changes angular position around the same fixed axle.
• Successive original blades enter the right-side contact area without changing count.
• Rotation is clockwise in this stated frontal arrangement, with the contacted side moving downward.
• Water continues beyond the wheel toward the tray without teleporting through solid parts.
• If the stream or first blade contact is hidden, startup order is inconclusive; a wheel already turning in the next frame is insufficient evidence.

6. Fix one failure

• Wheel starts too early: lengthen the initial gap-crossing phase before requesting rotation.
• Axle travels with the water: reinforce the support as a fixed background anchor.
• Blades become a blurred disc: request less rotation and broader readable blades.
• Stream misses the wheel: correct the authorized input alignment before changing motion wording.

7. Ending and limits

Finish while the original wheel turns slowly under the continuing stream, with its support unchanged.

No H3 run, hydraulic test, power calculation or efficiency measurement is supplied. Visible rotation cannot establish torque, useful load or real startup dynamics. The prompt is an untested creative suggestion and does not guarantee model performance.

The two-gear task transfers visible rotation between contacting solid teeth. This task uses a falling liquid stream, an initially still single wheel and repeated blade arrivals. Changing blade color alone would preserve the same causal sequence.
