Turn an auger and watch the original granules advance in its trough

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

1. Task and boundary

This shot separates a rotating screw from the stationary channel surrounding it. A shallow bed of existing granules lies between the flights of a horizontal auger. As the auger turns, the granules are pushed along the trough toward frame right while also rearranging locally. The useful evidence is that the helical surface turns in place, the channel stays still and the original material advances relative to fixed channel marks.

Use a slow, lightly filled illustrative mechanism. Granules need not travel as one rigid block or advance an exact pitch each revolution; slip, rolling and small local rearrangements can occur. Do not add a feed stream or discharge pile during this brief. The endpoint remains inside the visible trough, so there is no need to invent a hidden supply or claim a measured throughput.

2. Authorized first frame

Draw an original right-handed auger in a shallow, open-topped trough, or use an image you are authorized to adapt. Place its axis horizontally from left to right with both bearing supports visible. Show several clear flights and a modest quantity of contrasting granules resting in the lower part of the channel. The shaft and flights are one rigid rotating assembly; the trough walls and supports belong to the fixed frame.

Use an oblique view from slightly above the open side, with the right shaft end also readable. Show a rotation marker on that end and two fixed marks on the trough rim. Keep the granular bed low enough to expose contact with the flight faces. Avoid a dense opaque load or an enclosure hiding the entire screw. Leave space at the right within the trough for the material to advance without leaving the scene. Use coarse illustrative grains, not a texture that cannot be distinguished from the channel.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the complete prompt, check the available settings and cost estimate, then submit only when ready. This page supplies text; it does not upload an image or start a generation.

4. Prompt and timing

Use the supplied first frame. Keep the trough, rim marks and both bearing supports fixed. Rotate the original right-handed auger slowly clockwise as viewed from its right-hand end, conveying the visible granules toward frame right. The shaft stays on its original axis and the helical flights retain their pitch, diameter and connection to the shaft. Let the existing granules roll and rearrange locally as the moving flight faces push them along the stationary trough. Keep them contained by the channel floor and walls. Do not translate the screw, move the trough like a conveyor, rotate the entire granular bed with the shaft, or create a fresh stream of particles. Advance only a short distance within the visible channel. Slow the screw to a stop and let the remaining small particle movements settle without an abrupt freeze or reverse flow.

Opening: identify the fixed rim marks, shaft supports, flight spacing and initial granular bed before the first visible turn.
Middle: follow a few recognizable clusters relative to the fixed trough marks while the flight surfaces rotate past them. Look for contact-driven advancement rather than an entire bed sliding as one painted texture.
Ending: stop the auger before the material reaches the end of the visible channel. Allow a brief local settling beat while the shaft, channel and remaining granules retain their identities.

These beats are author suggestions, not exact model timing guarantees. Adapt their proportions to the clip length actually available.

5. Inspect the output

After inspecting your own output, record a time or frame, visible observation and pass, fail or inconclusive judgment for each condition. A convincing ending alone does not verify the preceding action.

The trough and supports stay still while the shaft turns on one fixed axis without moving lengthwise.
The same helical flights retain their handedness, pitch and diameter rather than becoming traveling rings or a straight moving blade.
Existing granules advance toward the right relative to the fixed rim marks, with local rolling or rearrangement permitted.
Contact remains plausible at the flight faces and channel boundaries; particles do not pass through solid walls or rise as an attached rotating shell.
No new feed stream or discharge pile appears, and the short advance ends with the original material still inside the visible trough.
If the granular bed hides the flights or particle motion cannot be distinguished from changing texture, record inconclusive rather than infer screw transport from rotation alone.

6. Fix one failure

If the whole trough moves, give the rim marks and bearing supports stronger contrast and explicitly keep them in fixed screen positions.
If the screw slides lengthwise, show both shaft supports clearly and remove wording about the screw advancing. Only the granules should progress along the axis.
If the bed rotates as a solid sleeve, reduce the fill level and request loose local rolling against the trough floor instead of perfect attachment to the flights.
If particles travel through a flight, simplify the schematic and slow the rotation so the pushing face remains visible. Avoid asking for a large advance in one beat.
If new granules appear at the left, state that the input contains the entire material supply for this clip. Reinspect the same initial bed after changing one instruction.

7. Ending and limits

The final view contains the same auger and trough with the granular material shifted a short distance rightward and settled. The final location does not prove a particular delivery rate, uniform mixing or complete transport efficiency. Preserve observations of the contact and relative motion during the turning phase.

Save your own generated result through the available result controls, together with the authorized input, exact prompt, settings and inspection notes.

No generated result, particle simulation, measured flow rate or physical auger test is supplied. The prescribed view and slow motion are author choices intended to expose continuity. A synthetic image may suggest contacts that are not mechanically consistent, so uncertain contact should remain inconclusive. Save the original authorized input and the actual prompt with your inspection record.

The conveyor task carries a parcel on a translating support surface. Here the trough is stationary and a rotating helical face redirects loose material along it. This also differs from a pump tube: there is no migrating wall pinch or liquid bolus, only visible granular contact with rigid flights.
