How to Choose the Right AI Video Model

Written by Michael

AI video models are designed for different creative needs. Some models focus on realistic visuals and cinematic quality, some are better for character consistency and motion control, while others are optimized for fast and affordable testing.

Choosing the right model before generating can help you achieve better results, reduce unnecessary trial and error, and save AI credits.

This guide explains common AI video model use cases, provides low cost testing strategies, and shares practical prompt examples to help you create better videos with fewer attempts.

3. Three Step Low Cost Testing Workflow

To avoid spending too many AI credits, we recommend generating videos in three stages.

Instead of creating the final version immediately, test your idea first, improve the prompt gradually, and use higher quality models only after confirming the direction.

Step 1: Validate the Concept (Low Cost)

Goal:

Make sure the AI understands your idea and the overall direction is correct.

Recommended Models:

  • Kling 2.5 Turbo

  • Hailuo 2.3 Fast

Tips:

  • Use shorter video durations

  • Focus on the concept rather than final quality

  • Check whether the scene, subject, and movement match your expectation

  • Avoid adding too many details before confirming the basic idea

Example:

Original idea:

"A girl dancing on the beach during sunset with a cinematic style."

First test:

Check only:

  • Is there a girl?

  • Is the location a beach?

  • Is the dancing motion correct?

  • Does the overall atmosphere match?

At this stage, the goal is not to create a perfect video. The goal is to confirm that the AI understands your creative direction.


Step 2: Improve the Result (Optimize Gradually)

After confirming the basic direction, improve the prompt step by step.

Change one element at a time so you can understand which adjustment improves the result.

Example:

Version 1:

"A girl dancing on the beach."

Version 2:

"A girl wearing a white dress dancing on the beach."

Version 3:

"A girl wearing a white dress dancing on the beach at sunset, with a slow camera push in shot."

Avoid changing multiple elements at the same time:

  • Character

  • Background

  • Style

  • Motion

  • Camera movement

Otherwise, it becomes difficult to identify which change affected the final result.


Step 3: Generate the Final Version (High Quality)

After confirming all important details, switch to higher quality models for the final generation.

Recommended Models:

  • Veo 3.1

  • Seedance 2.0

  • Kling 3.0

Recommended For:

  • Commercial videos

  • Marketing materials

  • Final published content

  • Professional creative projects

A practical workflow is:

Low cost model → Confirm concept → Improve prompt → High quality model → Final generation


4. Practical Prompt Tips: Help AI Better Understand Your Request

A good prompt should not only describe what you want to create, but also provide clear instructions about:

  • The subject

  • The environment

  • The movement

  • The camera

  • The visual style

  • The audio requirements

  • The elements that should remain unchanged

Clear instructions help AI generate more accurate and consistent results.


Tip 1: Describe the Structure Clearly

Instead of:

"A beautiful woman walking."

Use:

"A young woman walking along a quiet beach at sunset. The camera slowly follows behind her, creating a cinematic atmosphere with warm lighting and soft waves in the background."

A complete prompt usually includes:

Element

Example

Subject

A young woman walking on the beach

Scene

Sunset beach with waves and warm light

Action

Walking slowly while looking at the ocean

Camera

Slow tracking shot from behind

Style

Cinematic, realistic, emotional

Audio (Optional)

Soft ocean waves and gentle music


Tip 2: Describe Actions in Sequence

AI understands movement better when actions are described in order.

Instead of:

"A person sitting in a room."

Use:

"The character opens the door, walks into the room, looks around, and slowly sits down."

Useful action descriptions:

  • Walks toward the camera

  • Turns around slowly

  • Looks at the product

  • Picks up the object

  • Opens the door

  • Camera zooms in

  • Camera moves from left to right

  • Camera follows the subject from behind

Sequential descriptions help AI understand the beginning, middle, and end of an action.


Tip 3: Tell AI What to Keep Consistent

For character or product videos, clearly describe important details that should remain unchanged.

For Characters:

Example:

"Keep the same character appearance throughout the video. Maintain the same hairstyle, clothing, facial features, and color style."

For better consistency:

  • Keep the same face

  • Keep the same hairstyle

  • Keep the same clothing

  • Keep the same body proportions

  • Keep the same visual style


For Products:

Example:

"Keep the product shape, logo, color, and design unchanged. Show the product from multiple angles while maintaining accurate details."

For product videos, specify:

  • Product shape

  • Brand logo

  • Colors

  • Materials

  • Packaging details

  • Important design features

This helps prevent unwanted product changes during generation.


Tip 4: Describe Audio Requirements

If you need sound, specify it clearly in the prompt.

Example:

"Add natural environmental sounds, including ocean waves and light wind."

or:

"Include realistic dialogue with accurate lip synchronization."

Audio related instructions can include:

  • Background sounds

  • Voice style

  • Dialogue

  • Lip synchronization

  • Music atmosphere


Tip 5: Add Negative Instructions

Tell AI what you do not want. Negative instructions can help reduce common generation problems.

Examples:

Avoid:

  • Distorted faces

  • Extra fingers

  • Unnatural movements

  • Blurry details

  • Changing product designs

  • Incorrect text

  • Unrealistic reflections

Example prompt:

"A professional product advertisement video. Keep the product logo and packaging unchanged. Use smooth camera movement. Avoid distorted objects, incorrect text, and unrealistic reflections."


5. Prompt Examples: Ready to Use Templates

The following examples show how to structure prompts for different AI video creation scenarios. Adjust the details based on your project requirements and choose the model that best matches your goal.

Example 1: Cinematic Landscape Video

Prompt Examples:

1. "A cinematic shot of a person walking alone beside a peaceful lake at sunset. The camera slowly moves forward, capturing reflections on the water. Warm golden lighting, realistic details, shallow depth of field, professional film style."

2. "A breathtaking aerial view of a vast mountain valley covered with morning mist. The camera gently flies forward between the mountains, revealing rivers, forests, and sunlight breaking through the clouds. Cinematic composition, realistic environment, natural lighting, high detail, documentary film style."

3. "A quiet coastal village during a rainy evening. The camera slowly pans across old houses, wet streets, and ocean waves hitting the shore. Moody atmosphere, soft lighting, realistic textures, cinematic color grading, emotional storytelling style."

Recommended Models:

Veo 3.1 / Seedance 2.0


Example 2: Product Advertisement Video

Prompt Examples:

1. "A luxury perfume bottle placed on a marble table. The camera slowly rotates around the product while soft studio lighting highlights the glass texture and liquid inside. Premium commercial advertisement style, realistic reflections, elegant atmosphere."

2. "A high end smartwatch displayed on a sleek black surface. The camera smoothly pushes in toward the product, revealing the detailed metal frame, glowing screen, and refined design. Dynamic studio lighting, realistic materials, sharp focus, premium technology commercial style."

3. "A designer handbag resting on a modern chair in a luxury boutique. The camera slowly moves around the bag, showcasing the leather texture, stitching details, and elegant shape. Soft cinematic lighting, realistic shadows, fashion advertisement style, high end brand presentation."

Recommended Models:

Hailuo 2.3 / Seedance 2.0

Model Selection Guide:

  • Choose Hailuo 2.3 for general product showcases, commercial visuals, and standard advertisement videos.

  • Choose Seedance 2.0 when you have reference images, videos, or audio materials and want the generated video to follow specific visual styles, movements, or performances.


Example 3: Character Action Video

Character action generation works best when using motion reference inputs.

Instead of only describing an action with text, provide:

  • A clear character image

  • A reference video containing the desired movement

The reference video guides the character’s motion, while the prompt controls additional details such as appearance consistency, environment, and camera requirements.

Required Inputs:

Input

Recommendation

Character Image

A clear image showing the character’s face, clothing, and appearance

Motion Reference Video

A video containing the desired movement, action, expression, or performance


Prompt Examples:

1. "Transfer the motion from the reference video to the character. Keep the character’s face, hairstyle, clothing, and body proportions unchanged. Preserve natural body balance and accurate hand movements. Maintain consistent character appearance throughout the video."

2. "Apply the movement from the reference video to the character. Keep the same person, outfit, and visual details. Preserve realistic body motion, facial expressions, and natural interactions. Maintain smooth and accurate movement replication."

3. "Use the reference video as the motion guide. Keep the character’s original appearance, clothing details, and proportions unchanged. Ensure natural posture, realistic movement, and accurate action performance."

Recommended Models:

Kling 3.0 Motion Control / DreamActor M2.0

Note:

If you only provide text descriptions without a motion reference video, use general Text to Video models instead of Motion Control models.


Example 4: Dialogue Scene

Prompt Examples:

1. "Two people having a natural conversation in a coffee shop. They look at each other while speaking with realistic facial expressions and accurate lip movement. Cinematic camera angles, natural lighting, realistic environment."

2. "A father and daughter talking together in a cozy living room during the evening. They smile, react naturally, and maintain eye contact while having an emotional conversation. Keep the same characters, clothing, and appearance throughout the video. Realistic facial expressions, accurate lip synchronization, warm indoor lighting, cinematic family drama style."

3. "Two business professionals discussing a project in a modern office meeting room. They exchange ideas, gesture naturally, and respond to each other during the conversation. Keep the same characters and appearance throughout the scene. Realistic dialogue movements, natural body language, professional cinematic camera shots, realistic office environment."

Recommended Models:

Seedance 1.5 Pro / Veo 3.1


Example 5: Multi Character Story

Prompt Examples:

1. "A group of friends walking through a city street at night. Each character has a consistent appearance throughout the scene. The camera switches between wide shots and close ups while maintaining a cinematic storytelling style."

2. "A team of astronauts exploring an unknown planet with a futuristic landscape. Each astronaut has a consistent suit, appearance, and role throughout the scene. The camera captures wide shots of the alien environment and close ups of their reactions while they communicate and investigate. Cinematic lighting, realistic details, epic science fiction film style."

3. "A family spending a weekend together in a countryside house. Each family member maintains the same appearance, clothing, and personality throughout the video. The camera follows different moments, including cooking, playing outdoors, and sharing a meal together. Natural interactions, realistic emotions, warm lighting, cinematic storytelling style."

Final Tips

AI video generation works best through gradual improvement:

  • Start with a low cost model to test your idea.

  • Use reference images or videos when you need better character, product, or motion consistency.

  • Optimize your prompt step by step instead of changing many elements at once.

  • Use high quality models only after confirming the concept.

A clear prompt and the right model choice can significantly improve generation quality while saving AI credits.

Choosing the right AI model is not only about selecting the highest quality option. The best results come from matching the model’s strengths with your specific creative goal.
