How to Write Anime Video Prompts? How to Use AI to Make 2D Animation Cinematic? NadouPro Anime Video Prompt Guide

AI video in a 2D animation style has recently become a popular direction in creative circles: clean lines, cel-style coloring, hand-drawn textured backgrounds, plus motion and sound can give a short clip the feel of an anime episode in just a few seconds. But many people’s prompts either generate results that are too realistic or cause the action to fall apart. This guide breaks down how to write prompts for 2D-style video and pairs them with practical approaches in NadouPro.

Choose the Right Model: Anime Expressiveness Is the Key Benchmark

An anime style places high demands on a model’s ability to understand visual style. Among NadouPro’s video models, MiniMax-Hailuo 2.3 is the best option for anime expressiveness. Its visual tension and stylized performance suit action scenes and emotional scenes in a 2D animation direction. When you need dialogue scenes with audio-video synchronization, all NadouPro video models support audio-video synchronization, so you can use them with confidence.

Model selection advice: prioritize Hailuo 2.3 for stylized action scenes; for scenes that need stable multi-shot storytelling, try models that support intelligent multi-shot generation; for dialogue scenes, generate them with models that support audio-video synchronization, and handle the lines with Voice Dubbing.

Key Descriptive Words for a 2D Style

A 2D style should be described with "visible visual features" rather than abstract style names. The following categories are the most commonly used:

Clean anime linework: clear contour lines, expressive faces, flat color blocks, suitable for action scenes and character scenes;

Hand-drawn-feel backgrounds: soft light, hand-drawn textures, natural scenery, suitable for quiet fantasy or travel scenes;

Cinematic skylight: saturated sunset colors, cloud details, dramatic Rim Light, suitable for emotionally intense outdoor scenes;

Flat illustration style: simple shapes, clean color blocks, minimal texture, suitable for modern short films and explanatory content;

Ink-wash style: flowing ink tones, soft gradients, restrained use of color, suitable for historical or poetic subjects.

When writing prompts, put the style description at the beginning and state the visual effect you want directly. This is more stable than asking the model to "imitate a certain style."

Layered Prompt Structure

A useful 2D animation prompt can be built in four layers:

Layer 1, visual direction: set the overall look first, such as "clean 2D animation linework, cel-style coloring";

Layer 2, character details: the subject’s appearance, clothing, and expression;

Layer 3, environment and lighting: background, atmosphere, weather, and light direction;

Layer 4, cinematic language: shot size, angle, and camera movement.

Using a typical scene as an example, a high-energy fight scene could be written like this:

Clean 2D animation linework, cel-style coloring. In a narrow alley on a rainy night, a deep black scaled monster faces off against a samurai in a red kimono. The samurai moves with swift footwork, sparks burst as the blades collide, and the hem of the robe and strands of rain whip through the air with the action. Low Angle tracking shot, dramatic Rim Light, high-speed action scene, full of visual tension.

The advantage of this prompt is that everything is grounded in visible action and camera instructions, making it easier for the model to execute.

Three Essentials for Keeping a 2D Look

Use positive descriptions. Say what you want: clean lines, flat color blocks, hand-drawn backgrounds, clear silhouettes, and stable body structure.

Correct the output when it drifts. If the output is too realistic, push the prompt further toward 2D features by strengthening the descriptions of lines and color blocks.

Use reference images as a fallback. First use image generation to create a satisfying 2D-style baseline image, then use Image to Video or First/Last Frame mode to animate it. The style will be much more stable than with text-only descriptions.

Character Consistency: Use Reference Images to Lock the Protagonist

For anime-episode-style content, the biggest concern is having the character’s face change from episode to episode. The method is to turn the character into fixed reference material:

1. Use a character baseline image to lock the design. NadouPro’s Multi-Grid capability can produce a full-body Character Body 3-View and a Character Expression 9-Grid in one go, covering expressions from multiple angles;

2. When generating video, use Multi-reference mode with the character image and clearly state "keep the character’s appearance and clothing from the reference image";

3. For characters with many full-body action scenes, the reference image should show the full outfit, silhouette, and key details. Do not provide only a headshot.

Multi-Shot Storytelling: Break Big Scenes into Separate Shots

Epic-feeling scenes are rarely completed in a single shot. In practice, there are two approaches:

Storyboard first: use NadouPro’s Storyboard to split the script into a shot sequence with one click, generate each shot separately, then assemble them with Clip. This keeps the composition and rhythm of each shot controllable.

Write cinematic language into the prompt: within a single shot, clearly describe the shot size and movement—Close-Up, Full Shot, Low Angle, slow push-in, tracking shot, pan, Over-the-Shoulder Shot. Use shot-reverse-shot structure for dialogue scenes, and break tense passages into two groups of shots using the idea of cross-cutting.

Quick reference for common shot expressions:

• Shot-reverse-shot: dialogue and reaction shots alternate, suitable for dialogue-driven scenes;

• Cross-cutting: two lines of action appear alternately to create urgency;

• Crane and pan movement: smooth camera movement carries the transition;

• Bird’s-Eye Wide Shot: establishes scale and spatial relationships;

• Over-the-Shoulder Shot: anchors dialogue from a specific character’s perspective.

Sound: Audio-Video Synchronization Adds Value to 2D Video

When the sound in 2D animation is done well, the overall quality immediately rises a level. NadouPro’s approach:

Sound effects and ambient sound: all video models support audio-video synchronization, so sword clashes, city ambience, and footsteps can be generated together with the visuals;

Lines: use Voice Dubbing to generate character dialogue with natural emotional expression, and clearly write the speaker, the line content, and the tone requirements;

Music: use Text to Music to generate music that matches the scene’s emotion. Mureka V9 suits diverse soundtrack needs: give fight scenes fast-paced drums, and give lyrical scenes soft melodies.

Complete Workflow Example

1. Concept and script: clearly write the story and the 2D visual direction;

2. Character baseline: use Multi-Grid to generate the character’s 3-view design and Character Expression 9-Grid to lock the appearance;

3. Style baseline: use image generation to create a satisfying style frame as the starting point for Image to Video;

4. Storyboard breakdown: use Storyboard to split the script into shots, then generate the video shot by shot;

5. Sound production: produce Voice Dubbing and Text to Music separately, then align them during editing;

6. Edit into a finished video: use Clip to assemble shots, adjust the pacing, preview, and export.

Following this workflow, one person can also create a structurally complete 2D animated short film.

Common Questions

Q: How do you write effective prompts for 2D animation?
A: Start with the visual direction, then add the subject, action, scene, lighting, camera movement, and sound requirements in order. Style descriptions should be grounded in visible features: lines, color blocks, brushstrokes, and composition, rather than abstract adjectives.

Q: How can you keep a character consistent across shots?
A: A character baseline image plus Multi-reference mode is the core method. First lock the character with a 3-view design and Character Expression 9-Grid, then use the same set of references for every shot and state in the instructions that the character’s appearance should be maintained.

Q: How should dialogue and dubbing be handled?
A: Video models support audio-video synchronization and can directly generate visuals with sound. When you need finer control over lines, use Voice Dubbing to generate dialogue separately with natural emotional expression, then align it with the visuals.

Q: What length is suitable for a single video?
A: A single-shot short film is most stable at five to ten seconds. For complex action scenes, split them into multiple short shots and generate them separately, then assemble them into a complete sequence with Clip. This is much more controllable than forcing one long video to generate.

Q: What if the visuals always look too realistic?
A: Take three actions: strengthen the descriptions of linework and flat color blocks, guide generation with a 2D-style reference image, and switch to a model with stronger anime expressiveness. Most cases of "realistic drift" happen because the prompt contains too few 2D features.
