Draw the arms inward during a swivel-stool turn

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

1. Task and boundary

This shot coordinates a change in body pose with a change in depicted turning speed. One adult is already rotating gently with a swivel seat, arms extended away from the torso. The person brings both arms inward without pushing against the floor, and the person and seat then continue turning more quickly in the same direction. The fixed base and floor references distinguish that motion from a camera orbit or an entire stool sliding across the room.

Treat the shot as an illustrative movement brief, not a measured conservation experiment. Do not promise an exact speed ratio or infer torque from the generated image. Keep the person seated throughout, with feet clear of the floor and supported by a foot ring that rotates with the seat. No standing, jumping or dramatic high-speed spin is part of this task.

2. Authorized first frame

Use your own authorized image of a consenting adult, or an original clearly adult schematic figure. Show a swivel stool with a fixed base, one vertical center spindle and a seat with a rotating foot ring. Seat the person securely with feet resting on that ring, both arms extended moderately to the sides and elbows slightly bent. Keep hands and fingers distinct against a plain background.

Choose a fixed elevated oblique view that includes the whole seated body, seat edge, spindle, base and a few stationary floor marks. Add a small contrasting marker to the seat edge so its rotation can be compared with the torso. The base should have a recognizable fixed orientation. Avoid mirrors, loose garments covering the hands, other people or a wheeled base. The image supplies identities and geometry; the prompt supplies the intended initial gentle rotation.

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 camera, floor marks, stool base and vertical spindle position fixed. Begin with one consenting adult seated on the swivel seat, turning gently clockwise together with the seat and rotating foot ring. Keep both feet on that ring, clear of the floor, with no push or external contact. During the continuing turn, bring both extended arms inward toward the chest in one smooth motion, keeping both hands distinct. As the arms come inward, depict a gradual increase in the same clockwise turning speed. The torso, pelvis and seat keep their shared turning orientation; the arms change pose relative to the torso without swapping sides or passing through it. Preserve the same person, clothing, stool and limb count. Do not orbit the camera, slide the base, add a floor kick or change playback speed midway. Finish with the arms held inward and a brief continuing faster turn, without an abrupt stop, reverse turn or second arm-opening cycle.

Opening: establish a short gentle shared turn with the arms extended. Use the seat marker and fixed floor marks to show that the base stays still and the viewpoint does not move.
Middle: bring both arms inward while the seat and body keep turning in the same direction. Compare rotation over similar time intervals before and after the inward movement, without claiming a calibrated angular rate.
Ending: keep the arms close to the chest during a short continuing turn that is visibly faster than the opening. The endpoint is an ongoing motion state, not a frozen pose or a completed stop.

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 base, spindle position, camera and floor references remain fixed while the seat, foot ring and seated person turn together.
The feet stay supported on the rotating ring and clear of the floor, with no new push, kick or contact supplying a visible extra drive.
Both original arms move inward relative to the torso, with distinct hands and stable limb connections rather than a body morph or hand merge.
The pelvis and torso retain their shared turning orientation with the seat; the task does not become a torso twist over a stationary pelvis.
Comparable visible intervals show a qualitative increase in clockwise rotation as the arms come inward, followed by a brief faster continuation with the arms kept in.
If occlusion, a camera move or inconsistent frame timing prevents a speed comparison, record inconclusive; arm position and a blurred ending alone do not establish the requested change.

6. Fix one failure

If the camera circles the person, strengthen the stationary floor references and keep the base marker fixed. Remove orbit or cinematic sweep language.
If the person twists while the seat stays still, name the seat marker, pelvis and torso as a shared turning assembly. Only the arms should change their pose relative to it.
If a floor push appears, make the rotating foot ring and both supported feet clearer in the authorized input. Keep the feet away from stationary supports.
If the speed change is hidden by blur, slow the entire illustrative motion and reduce the requested contrast. Keep enough identifiable seat and body features for comparison.
If hands merge at the chest, stop the inward movement with a small visible separation between them. Recheck limb identity and the simultaneous turn after one revision.

7. Ending and limits

The last part retains inward arms and a visibly faster continuing turn in the same direction. The fixed base and floor marks remain in view. Do not label the ending as a stable stop or use its appearance to calculate a physical speed ratio; the useful record is the visible relationship between arm movement and shared rotation.

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

No generated clip, human motion measurement or physical spinning trial is supplied. A model may imitate faster rotation through blur, editing or inconsistent geometry. Inspect the actual frame sequence and keep uncertain timing inconclusive. Use only consented or original adult imagery, and retain the input, prompt and actual observations with the saved output.

The chair camera-arc task moves the viewpoint around a stationary chair. Here the viewpoint and base remain fixed while a seated person and seat rotate, and the arms change radial position. It also differs from a seated torso twist: the pelvis is not anchored to a nonturning seat, and the requested event includes a qualitative speed change.
