Purse the lips once without turning it into a jaw movement

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

1. Task and boundary

Follow a closed mouth from neutral to a small pucker and back. The mouth corners move inward as the lip contour projects slightly forward; the chin should not lead the action. A narrower dark line alone is weak evidence because lighting or a head turn can produce a similar change. Use an oblique portrait to inspect both width and projection.

Keep the action small and non-contact. There is no kiss toward another person, speech, blowing object or changing facial identity. Avoid an extreme caricature pucker that needs large cheek or jaw changes. The purpose is to separate local lip-shape motion from movement of the whole lower face, using visible comparisons rather than an anatomical measurement.

2. Authorized first frame

Provide a photograph or illustration you own or may use, with the depicted adult’s permission when using a real person. Use a slight three-quarter view with both mouth corners visible and a readable near-side lip profile. Start with a relaxed, closed mouth; leave the chin, nose tip and enough cheek in frame to reveal unwanted head turning.

Choose soft consistent lighting that still separates the lip edge from nearby skin. Keep hands, hair and clothing away from the mouth. Avoid an opening image with exposed teeth, a smile or an already pursed mouth. Do not change the camera angle during the clip to reveal the pucker; establish the useful view in the first frame.

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

Begin with my authorized image of the same adult at a slight three-quarter angle, lips naturally closed and jaw relaxed. Keep the camera, head, nose tip and chin position steady. Draw the original mouth corners gently inward and let the closed lip contour project a little forward. Keep both lip borders continuous and preserve the original lip texture and proportions. Pause briefly at the small pucker, then release smoothly until the original mouth width and profile return. Keep the mouth closed and the cheeks close to their starting volume. Do not open the jaw, expose teeth, inflate the cheeks, turn the head or push the entire chin forward. No contact with another person, speech, new face, cut or zoom. End in the same relaxed closed-mouth position.

Opening: locate both mouth corners and compare the lip profile with the nose and chin.
Middle: inspect inward corner travel and slight forward lip projection together; either alone is insufficient.
Ending: follow the release until the original closed contour and mouth width are visible again.

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.

Both original mouth corners move inward rather than being replaced by a smaller mouth.
The near-side lip contour projects slightly while the chin remains a stable reference.
The upper and lower lip boundaries stay continuous without tearing or doubling.
The mouth remains closed, with no unexplained teeth or dark open cavity.
The release restores the original mouth width and neutral profile.
If the view hides a corner or cannot show projection, mark that condition inconclusive.

6. Fix one failure

The chin advances with the lips: anchor the chin and shorten the requested forward travel.
A dark oval replaces the closed seam: repeat closed-mouth wording and remove blowing or speaking cues.
The cheeks inflate: specify near-original cheek volume and remove air or puff language.
The pucker is only a texture change: choose an input with a clearer near-side lip contour.
The face turns to reveal the action: fix the three-quarter view from the start rather than requesting a reveal.

7. Ending and limits

End with the same lip edges relaxed at the starting width, jaw still closed and chin in its original place.

This page supplies an untested shot plan, not a generated example or measured lip displacement. A convincing contour does not establish speech ability, muscle function or emotional meaning. Treat hidden surfaces and subtle depth changes conservatively.

The neighboring portrait exercise Eyes first, head second: a small gaze-and-turn exercise separates pupil direction, nose position and shoulder stability. Those references help identify unwanted head motion during a lip pucker. The action here is different: the lip contour narrows and projects while the jaw stays nearly fixed; it does not need an eye movement followed by a turn.
