Pinku AI Image to Video Models Guide

Pinku AI lets you turn a still image into a short animated video.

There are currently four Pinku AI video models:

• Pulse
• Pulse Motion
• Flow Mini
• Flow

All four models create image-to-video animations, but they are not designed for the same kind of result.

The most important difference is simple:

Pulse and Pulse Motion are image-first models.
They mostly animate what is already visible in the image. The prompt is optional and may only guide the result lightly.

Flow Mini and Flow are prompt-first models.
They are designed to follow your written instructions much more closely. With Flow models, a good prompt can completely change the final video.

If you do not want to write a prompt, use Pulse Motion.

If you want the video to follow your instructions, use Flow Mini or Flow.

If you want the highest quality result, use Flow.

Quick Recommendation

If you are not sure which model to use, start here:

In simple terms:

Use Pulse Motion if you want easy results without prompt engineering.
Use Flow or Flow Mini if you want the video to follow your instructions.

Model Comparison

Understanding Each Video Model

Pulse

Stable · Subtle · Simple

Pulse is the most conservative Pinku AI video model.

It creates light motion from the original image and keeps the result close to the original composition. It is ideal for simple animations, subtle breathing, small facial movement and GIF-like results.

Pulse is not designed for complex actions or strong motion. It usually keeps movement restrained and stable.

Use Pulse when you want:

• A subtle animation
• Stable results
• Minimal motion
• A simple GIF-like effect
• Light breathing or micro-movement
• A result close to the original image

Pulse is not the best choice if you want the model to follow a detailed action prompt.

Pulse Motion

Expressive · Repetitive · Physically Enhanced

Pulse Motion is a more dynamic version of the Pulse experience.

It is especially good at repetitive movement, expressive physical reactions, breathing, hair movement, fabric movement and natural body physics.

Pulse Motion is usually the best option when you do not want to write a prompt. In many cases, you can generate an attractive video directly from the image without adding any text.

The prompt can help a little, but Pulse Motion may still ignore instructions if they do not match the original image.

Use Pulse Motion when you want:

• Stronger movement than Pulse
• Repetitive motion
• Natural body physics
• Hair or fabric movement
• Expressive animation without writing a detailed prompt
• A more dynamic result with minimal effort

Pulse Motion is the recommended model for users who want quick, attractive video results without needing prompt engineering.

Flow Mini

Fast · Prompt-Based · Efficient

Flow Mini is part of the Flow video generation family.

Unlike Pulse and Pulse Motion, Flow Mini is designed to pay much more attention to the prompt. The image is still important, but the written instruction becomes a major part of the final video.

Flow Mini is optimized to be faster and lighter than Flow. This makes it ideal when you want more control than Pulse Motion, but you also want to use your generations efficiently.

Use Flow Mini when you want:

• The model to follow your prompt
• Faster prompt-based video generation
• A lighter alternative to Flow
• Good quality with better efficiency
• To test several prompt ideas before using Flow
• Better value for lower-tier plans

Flow Mini is a great choice when you want control, but you also want to save generations.

Flow

Highest Quality · Best Prompt Following · Cinematic

Flow is the strongest Pinku AI video model.

It is designed for users who want the best possible quality, stronger prompt interpretation, more cinematic movement and better control over the final video.

With Flow, the prompt matters much more than with Pulse or Pulse Motion. A vague prompt will usually produce a weaker result. A clear, structured prompt can make a huge difference.

Use Flow when you want:

• The highest quality video model
• The best prompt following
• More cinematic movement
• Better control over the action
• More accurate camera movement
• More intentional results

Flow is the recommended model when you know what you want and you are ready to describe it clearly.

The Biggest Difference: Image-First vs Prompt-First Models

The most important thing to understand is this:

Pulse and Pulse Motion are image-first models

These models mostly animate what is already visible in the image.

The prompt is optional. It can help guide the result, but the model may ignore it, especially if the prompt asks for something that does not match the original pose, framing or composition.

For example, if the image shows a character standing still, asking for a complex running sequence will likely produce unstable results.

Pulse and Pulse Motion work best when you let the image guide the animation.

Flow Mini and Flow are prompt-first models

Flow Mini and Flow still use the image as the foundation, but the prompt has a much stronger influence.

These models are designed to understand and execute clear written instructions.

This means that prompt quality matters much more.

With Pulse and Pulse Motion, the prompt can be optional.

With Flow Mini and Flow, the prompt is one of the most important parts of the generation.

A good prompt can create a much better video.

A vague prompt can create a weak or confusing result.

The Golden Rule for Flow Prompts

For Flow Mini and Flow, do not only describe the image.

The model already uses the image as the visual foundation.

Instead, describe what should happen next.

Good Flow prompts usually answer these questions:

1. What is the subject doing?
2. How does the action start?
3. What happens next?
4. How should the camera move?
5. What should the final moment look like?
6. Are there any objects, liquids, props or effects that need a clear source?

This is especially important for complex actions.

A short prompt like:

Dive into the pool

is usually too vague.

A better prompt explains:

• where the character starts
• how they turn toward the pool
• how they jump
• how they enter the water
• what happens after impact
• what the camera should show

Simple Prompts vs Step-by-Step Prompts

For Flow Mini and Flow, there are two useful prompt styles.

Use a simple motion prompt when you want subtle or medium movement.

Use a step-by-step prompt when you want the model to perform a more complex action.

Simple Motion Prompt

Use this structure for simple animations:

[Primary motion], [camera movement], [environment or atmosphere], [speed and intensity]

Example:

The character slowly turns their head toward the camera while breathing naturally, their hair sways softly, warm light reflections move in the background, camera slowly pushes in, smooth natural motion at moderate speed

This works well for:

• Breathing
• Smiling
• Head turns
• Hair movement
• Subtle body motion
• Camera push-in
• Soft environmental motion
• Simple expressive acting

Step-by-Step Action Prompt

Use this structure when the action has several stages:

A single continuous cinematic shot with a clear step-by-step sequence.

Step 1: [Starting setup]
Step 2: [First action]
Step 3: [Second action]
Step 4: [Main action or payoff]
Step 5: [Final expression or reaction]

Then add camera, atmosphere, pacing and important constraints.

Example:

A single continuous cinematic shot with a clear step-by-step sequence.

Step 1: The character smiles at the camera beside the pool.

Step 2: They turn toward the water, their hair moving naturally.

Step 3: They make a playful jump into the pool.

Step 4: They enter the water, creating a large visible splash and ripples across the surface.

Step 5: The camera holds on the splash and moving water for a moment.

Warm steam drifts through the scene, soft reflections shimmer in the background, smooth expressive motion, medium-wide shot, slow cinematic camera push-in.

Step-by-step prompts are especially useful when the scene includes:

• Object interaction
• Body movement
• Water
• Clothing or fabric changes
• A visible before-and-after effect
• A clear final reaction
• A complex action that should happen in a specific order

Prompting Object Interactions

When your scene includes an object, make sure the object exists before it is used.

Bad:

The character grabs a glass and pours water

Better:

Step 1: A small table is visible beside the pool with a glass of water on it.
Step 2: The character turns toward the table and reaches for the glass.
Step 3: The character clearly picks up the glass and holds it in their hand.
Step 4: Only after the glass is visible, the character tilts it and pours the water.

This helps prevent props, liquids or effects from appearing from nowhere.

Useful phrases:

• The object is visible before the action starts
• The character clearly picks up the object before using it
• The water comes only from the glass
• No random water streams
• No sudden cuts
• No teleporting objects
• One continuous shot

Prompting Water, Fabric and Physical Effects

Flow models can create more dynamic action, but water and fabric effects work best when they are described clearly.

For water scenes, describe:

• where the water comes from
• when the water appears
• how it moves
• what it affects
• what remains after the action

Example:

The water flows only from the glass, splashing naturally onto the fabric and creating visible wet marks. Droplets scatter through the air and run down the shirt. No water appears before the glass is tilted.

For jumping into water, describe:

• starting position
• direction
• jump
• water entry
• splash
• ripples
• final camera hold

Example:

The character stands at the edge of the pool, turns toward the water, makes a playful jump, dives cleanly into the pool, creates a large splash with droplets flying upward, and ripples spread across the water surface.

Recommended Prompt Structure

For most Flow Mini and Flow videos, use this structure:

[Subject action], [chronological sequence if needed], [camera movement], [environment or atmosphere], [speed and intensity], [constraints]

Example:

A single continuous cinematic shot. The character smiles at the camera, turns toward the pool, takes a playful step and jumps into the water, creating a large splash and spreading ripples across the surface. Warm bathhouse steam drifts through the air, water reflections shimmer in the background, camera slowly pushes in, smooth energetic motion at moderate speed.

This structure helps the model understand:

1. What the subject is doing
2. In what order the action should happen
3. How the camera should move
4. What the atmosphere should feel like
5. How intense or fast the motion should be
6. What must not happen randomly

Motion Vocabulary

Use clear action verbs. Flow models perform better when the movement is concrete.

Good motion examples:

• Slowly turns their head
• Leans toward the viewer
• Reaches out with one hand
• Looks back over their shoulder
• Steps toward the pool
• Jumps into the water
• Picks up the glass
• Tilts the glass
• Blows a kiss
• Gives a quick wink
• Smiles playfully
• Their hair swings naturally
• Their clothing moves with the motion

Avoid vague instructions like:

• Make it cinematic
• Add movement
• Make it cool
• Improve the video
• Animate it nicely

Be specific. Flow models perform much better when the action is clear.

Camera Movement

Tell the model how the camera should behave.

Good examples:

• Camera slowly pushes in
• Slow dolly zoom
• Subtle handheld movement
• Camera pans slightly to the left
• Soft close-up movement
• Cinematic orbital camera motion
• Camera slowly tilts upward
• Medium shot
• Medium-wide shot
• Close-up ending

Camera instructions are especially useful for Flow and Flow Mini.

Do not overcomplicate the camera if the character action is already complex.

For complex actions, a simple camera instruction is usually better:

medium-wide shot, one continuous shot, slow cinematic camera push-in

Environment and Atmosphere

Use this part to improve mood and realism.

Good examples:

• Soft shadows moving across the scene
• Warm cinematic lighting
• Fog drifting in the background
• Sunlight flickering through the window
• Neon lights glowing softly
• Soft rain in the background
• Gentle wind moving the hair
• Warm bathhouse steam
• Shimmering water reflections
• Ripples spreading across the pool

These details help the video feel more alive.

Speed and Intensity

Control how strong or subtle the movement should be.

Good examples:

• Slow smooth motion
• Subtle natural movement
• Moderate speed
• Intense but controlled movement
• Gradual acceleration
• Gentle repetitive motion
• Smooth rhythmic motion
• Energetic but controlled pacing
• Fluid cinematic pacing

This is especially important when you want to avoid artifacts.

Prompt Examples by Model

Pulse Example

Best when you want a simple, subtle animation:

Subtle breathing, soft facial movement, minimal camera motion, smooth natural pacing

Pulse may not follow every word exactly. The goal is to gently guide the animation while keeping the result stable.

Pulse Motion Example

Best for expressive repetitive movement:

Natural repetitive body movement, visible breathing, hair moving slightly, subtle camera push-in, smooth rhythmic motion

Pulse Motion is a strong choice when you want a more dynamic result without needing a complex prompt.

Flow Mini Example

Best for faster prompt-based generation:

A single continuous shot. The character slowly turns their head toward the camera while breathing naturally, their hair sways softly, warm lighting and water reflections move in the background, camera pushes in slightly, smooth cinematic movement at moderate speed.

Flow Mini is ideal when you want the model to follow your idea, but you also want faster and lighter generations.

Flow Example

Best for maximum quality and prompt control:

A single continuous cinematic shot with a clear step-by-step sequence. Step 1: The character smiles at the camera beside the pool. Step 2: They turn toward the water, their hair moving naturally. Step 3: They make a playful jump into the pool. Step 4: They enter the water, creating a large splash and ripples across the surface. Step 5: The camera holds on the splash and moving water for a moment. Warm bathhouse steam drifts through the scene, soft reflections shimmer in the background, smooth expressive motion, medium-wide shot, polished cinematic pacing.

Flow is the best choice when the prompt matters and you want the highest quality result.

Good Prompt vs Bad Prompt

Bad Prompt

Make it move and look cinematic

This is too vague. The model does not know what should move, how the camera should behave or what kind of cinematic style you want.

Better Prompt

The character breathes softly and slowly turns their head, camera gently pushes in, warm cinematic lighting, smooth subtle motion

This is much better because it defines the subject movement, camera movement, lighting and motion intensity.

Bad Complex Prompt

Dive into the pool

This is too short for a complex action. The model does not know where the character starts, how they move, how they enter the water or what the final shot should show.

Better Complex Prompt

A single continuous cinematic shot with clear step-by-step action. Step 1: The character stands at the edge of the pool, smiling at the camera. Step 2: They turn toward the water. Step 3: They make a playful jump into the pool. Step 4: They enter the water, creating a large splash. Step 5: Ripples spread across the surface as the camera holds on the splash. Warm steam, shimmering reflections, smooth energetic motion, medium-wide shot.

Advanced Prompt Examples

Playful Wink and Kiss

A single continuous cinematic shot. The character leans slightly toward the viewer, smiles playfully, gives a quick wink and blows a kiss directly to the camera. Their hair moves softly with the motion, warm steam drifts in the background, water reflections shimmer across the room, camera slowly pushes in, smooth expressive anime motion at moderate speed.

Glass of Water Interaction

A single continuous cinematic anime shot with a clear five-step sequence.

Step 1: The character smiles playfully at the camera beside the indoor pool. A small table or pool ledge is visible on the right side with a glass of water on it.

Step 2: The character turns their body toward the table, their hair swinging softly, and reaches for the glass with one hand.

Step 3: The character clearly picks up the glass and turns back toward the viewer, holding the full glass in front of them.

Step 4: The character tilts the glass and pours the water onto their shirt. The water flows only from the glass, splashing naturally onto the fabric and creating visible wet marks. No water appears before the glass is tilted.

Step 5: The character lowers the empty glass, leans slightly toward the camera, gives a cheeky wink and smiles playfully.

Warm steam drifting through the bathhouse, shimmering water reflections, natural fabric movement, realistic droplets, expressive body motion, smooth camera push-in, polished cinematic pacing.

Jump Into the Pool

A single continuous cinematic anime shot with clear step-by-step action.

Step 1: The character stands at the edge of the indoor pool, smiling playfully at the camera.

Step 2: The character turns their body toward the pool, their hair swinging naturally with the motion.

Step 3: The character takes a quick step and makes a playful jump into the pool.

Step 4: The character dives cleanly into the water, creating a large visible splash with droplets flying upward and ripples spreading across the surface.

Step 5: The camera lingers on the splash and the disturbed water for a moment after the character enters the pool.

Warm bathhouse steam, shimmering water reflections, smooth expressive anime motion, energetic but controlled pacing, medium-wide shot, one continuous shot, realistic water physics.

Common Mistakes

Asking for actions that contradict the image

The model works best when the requested action is physically possible from the original image.

If the image shows a person sitting still, asking for a full running sequence may produce artifacts or unstable movement.

Better:

The character shifts slightly in the chair, breathing naturally, camera slowly pushes in, soft indoor lighting

Writing vague prompts

Avoid prompts like:

Make it beautiful

Add motion

Make it realistic

Make it cinematic

Instead, describe exactly what should happen:

The character slowly turns their head toward the camera, hair moves gently, camera pushes in slightly, warm cinematic lighting, smooth natural motion

Adding too many actions without sequence

Do not overload the prompt with many actions unless you put them in a clear order.

Avoid:

The character turns around, walks forward, waves, changes pose, smiles, jumps, splashes water and the camera spins around them

Better:

Step 1: The character smiles at the camera. Step 2: The character turns toward the pool. Step 3: The character jumps into the water. Step 4: A large splash appears. Step 5: Ripples spread across the pool.

Complex prompts work better when they are chronological.

Using Flow without a clear prompt

Flow and Flow Mini are much more prompt-sensitive than Pulse models.

If you use Flow with a weak prompt, you may waste the model's potential.

For Flow models, the prompt is not just decoration. It is the main instruction.

Forgetting the source of an object or effect

If you want the model to use a prop, liquid or object, introduce it before the action.

Instead of:

The character pours water

Use:

A glass of water is visible on the table. The character picks up the glass. Only after the glass is visible in their hand, the character pours the water.

For Flow models, prompt quality can completely change the final video.

Ask Grok or ChatGPT for Better Video Prompts

If you are not sure how to write a good video prompt, you can ask an AI assistant to help you.

For best results, we recommend using Grok first, especially for visual prompt assistance and creative motion ideas. If you do not have access to Grok, you can also use ChatGPT or another AI assistant.

The best method is to upload the same image you want to animate in Pinku AI and ask the assistant to create a prompt for a Wan 2.2 image-to-video model.

This helps the assistant understand the character pose, camera angle, expression, outfit, background and what kind of motion is realistic for that image.

Use this helper prompt:

I want to animate this image using a Wan 2.2 image-to-video model inside Pinku AI.

Please analyze the image and write a video motion prompt that is physically plausible based on the pose, framing, camera angle and composition.

The prompt should focus on what happens next in the video, not only on describing what is already visible in the image.

Use one of these two structures:

For simple motion:
[Primary motion], [camera movement], [environment or atmosphere], [speed and intensity]

For complex actions:
A single continuous cinematic shot with a clear step-by-step sequence.

Step 1: Initial setup
Step 2: First action
Step 3: Second action
Step 4: Main payoff
Step 5: Final reaction

Important guidelines:

- Keep the action compatible with the image.
- Use clear chronological steps if the action has multiple parts.
- Make sure objects appear before they are used.
- Make the source of liquids, props or effects clear.
- Avoid random objects appearing from nowhere.
- Avoid sudden cuts or teleporting objects.
- Use one continuous shot.
- Use concrete action verbs.
- Include camera movement only if it helps the scene.
- Include atmosphere or lighting details if useful.
- Control the speed and intensity of the movement.
- Keep it concise and optimized for Wan 2.2 image-to-video generation.

Pulse Motion is designed to produce attractive movement directly from the image and usually works better than Pulse when you want stronger motion.

Which Pinku AI video model follows prompts better?

Flow and Flow Mini follow prompts much better than Pulse and Pulse Motion.

If you want the model to actually execute a written instruction, use one of the Flow models.

Why does Pulse ignore my prompt?

Pulse is an image-first model. It mostly animates what is already visible in the image.

If your prompt asks for something that contradicts the pose, framing or composition, Pulse may ignore it or only follow it partially.

How do I write better prompts for Flow?

Use a clear prompt structure.

For simple motion, use:

[Primary motion], [camera movement], [environment or atmosphere], [speed and intensity]

For complex actions, use a chronological step-by-step prompt:

Step 1: Setup
Step 2: First action
Step 3: Second action
Step 4: Main action
Step 5: Final reaction

Clear and specific prompts work much better than vague prompts.

Should I use Flow Mini before Flow?

Yes, Flow Mini is a good option for testing prompt ideas before using Flow.

Once you find a prompt that works well, you can use Flow for the highest quality version.

Why does my video look unstable?

Video instability usually happens when the prompt asks for too much movement, contradicts the original image or includes too many actions at once.

For better results, keep the action physically plausible and focus on one main movement, or use a clear step-by-step sequence.

Why did an object or water appear from nowhere?

This usually happens when the prompt uses an object, liquid or effect without clearly introducing it first.

For better results, make the object visible before it is used.

Example:

A glass of water is visible on the table. The character picks up the glass. Only after the glass is visible in their hand, the character pours the water.

What is the best prompt style for complex actions?

For complex actions, use a step-by-step prompt.

This is useful for actions like jumping into a pool, picking up an object, pouring water, changing pose or creating a clear before-and-after effect.
