Pull a toy car back, release it and inspect forward travel

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

1. Task and boundary

Draw a familiar pullback toy car backward a short distance on a flat surface, then release it. Show the same car moving forward after the fingers are clear. Keep its front direction fixed throughout so backward loading and forward travel can be distinguished without a cut.

This original scene proposal is untested. Use a toy intended for a simple pullback action, shown without brand markings. Exclude internal spring diagrams, speed promises, distance guarantees and a motor appearing as an invented explanation.

2. Authorized first frame

Use a photograph or accurate drawing you own or have permission to use. Show one small toy car on a plain tabletop facing right, with the original hand resting on its roof. Both near-side wheels are visible, and one has a small plain tracking mark.

Frame a short backward loading area to the left and a clear forward runout to the right. Keep a fixed table feature behind the starting position. Avoid slopes, traffic scenes and fingers hiding all wheel contact with the surface.

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 one pullback toy car facing right on a level table, with the original hand on its roof and both near-side wheels visible. Lock the camera and table. Draw the same car a short distance left without turning its body, letting its wheels roll backward against the surface. Pause briefly at the pulled-back position. Then open the fingers and lift the hand fully clear. Only after release, let the car travel forward to the right with its wheels rotating in the forward rolling direction. Keep the body rigid, its front facing right and the wheel centers attached. Let it slow to a stop within the frame. No hand pushing during the forward run, invisible jump, body reversal, second car, drifting table, speed readout, camera tracking or cut.

1. Establish, first fifth: identify the fixed front direction, wheel contact and original roof grip.
2. Load and release, middle three fifths: inspect backward rolling, the brief pause and fingers leaving the roof.
3. Run, final fifth: follow forward travel with a clear hand gap, then hold the stopped car.

5. Inspect the output

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

• The car first moves backward while still facing its original forward direction.
• The wheels roll during the pullback rather than sliding as frozen discs.
• The hand is visibly clear before the main forward run begins.
• Forward travel reverses wheel rotation without turning the car body around.
• The same car stops within the visible tabletop area.
• If the hand gap is hidden, mark release-before-travel timing inconclusive.

6. Fix one failure

• The car turns around: retain the front marker at the same body end throughout.
• The hand secretly pushes: show a complete finger-to-roof gap during forward motion.
• The wheels freeze: expose one simple wheel mark and keep the roll slow enough to inspect.
• The car teleports from its loaded position: preserve the brief pause and initial forward frames.
• The run leaves the frame: shorten the requested travel and reserve more forward space.

7. Ending and limits

End with the original car stopped farther forward, its front unchanged and the operating hand fully clear.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 output, toy test, stored-energy measurement or performance comparison is supplied. Visible release and motion cannot verify the hidden mechanism or predict the distance of a real toy.

The rolling-cylinder task covers one direction of travel. This car adds a visible backward loading phase, release and forward reversal while its body keeps the same heading.
