Pinku AI - Image to Video Guide

Turn a still image into a short animated video using advanced motion modeling.

Pulse and Pulse Motion

Pulse

Stable, controlled, reliable. Pulse generates subtle, conservative motion from an image. It is ideal when stability matters more than intensity. Movement is limited and restrained.

Pulse Motion

Dynamic, expressive, physically enhanced. Pulse Motion uses enhanced physics training to produce stronger motion dynamics and natural physical reactions. It may take more risks and occasionally introduce artifacts, but results feel more alive.

Use Pulse Motion when you want:

• Dramatic breathing.
• Hair movement.
• Dynamic camera feel.
• Stronger emotional intensity.

How the Model Works

The model animates primarily based on what is already happening in the image. It does not create completely new actions from scratch. It interprets visual cues and expands them into motion.

Important:

• A prompt is optional, but prompts help direct the video.
• The image defines the core action.
• The model may partially ignore prompts that contradict the image.
• It performs best when the requested motion is plausible.

What the Model Does Well

• Enhances implied motion.
• Adds breathing and subtle body movement.
• Adds environmental atmosphere.
• Creates cinematic camera movement.
• Simulates natural physics, especially in Pulse Motion.
• Adds subtle facial and micro-movements.

What the Model Does Not Do Well

• Completely change the pose.
• Add new limbs or complex new actions.
• Turn static subjects into unrelated actions.
• Follow prompts that contradict the image.
• Create complex multi-stage choreography.

If the image shows a person standing still, asking for running at full speed will likely cause instability or artifacts.

Prompt Structure

If you use a prompt, follow this structure:

[Primary motion], [camera movement], [environmental effects], [speed modifiers]

This structure aligns with how both Pulse models interpret motion.

How to Write Each Section

1. Primary Motion

Describe the subject's movement using precise verbs.

Good examples:

• Breathing heavily.
• Slowly turning head.
• Hair gently fluttering.
• Subtle shoulder movement.
• Eyes blinking naturally.

Avoid vague wording like cool animation, cinematic vibe, or nice movement.

2. Camera Movement

Define camera behavior clearly:

• Camera pushes in.
• Slow dolly out.
• Orbital pan around subject.
• Subtle handheld movement.
• Slight tilt upward.

Explicit camera instructions significantly improve cinematic results.

3. Environmental Effects

Enhance realism and depth:

• Dim lighting with soft shadows.
• Sunlight flickering through leaves.
• Fog drifting in the background.
• Soft rain falling.
• Dramatic backlighting.

These influence mood, not structure.

4. Speed Modifiers

Control how strong the motion feels:

• At moderate speed.
• Slow smooth motion.
• Intense rapid movement.
• Gradual acceleration.
• Subtle natural pacing.

Speed modifiers are especially effective when using Pulse Motion.

Full Prompt Examples

Example 1 - Subtle Cinematic

Woman breathing slowly, camera pushes in for a close-up, dim lighting with soft shadows, smooth natural motion

Example 2 - Dynamic Motion

Young woman breathing heavily with visible chest movement, camera slowly pushes in while slightly tilting upward, dramatic low lighting with moving shadows, intense gradual zoom at moderate speed

Example 3 - Environmental Enhancement

Hair gently moving in the wind, slow orbital camera movement, sunlight flickering through trees, soft slow-motion pacing

Pro Tips

• Match the image: If the image shows subtle emotion, request subtle motion.
• Less is more: Overcomplicated prompts reduce reliability.
• Avoid contradictions: Do not request actions that are physically implausible.
• Choose the right model: Use Pulse for stability and Pulse Motion for expressive realism.

Choosing Between Pulse and Pulse Motion

Final Takeaway

Pulse models do not invent motion randomly. The image defines the action, the prompt refines it, and the model executes it.
