AniSora

Dive into AniSora, the next-gen open-source anime video generation model that empowers creators, researchers, and developers with state-of-the-art tools for animation creation.

What is AniSora?

AniSora is a revolutionary open-source anime video generation model developed by Bilibili. Designed to push the boundaries of AI in animation, AniSora allows users to create high-quality anime-style videos from static images, interpolate frames, and even generate videos guided by specific visual cues. Whether you're a developer, artist, content creator, or AI researcher, AniSora gives you unprecedented creative control over the animated content generation process.

What sets AniSora apart is its large-scale training data — over 10 million high-quality anime videos — and its innovative spatiotemporal masking module. This makes AniSora uniquely capable of producing visually stunning, temporally consistent animations.

Why AniSora Matters

In a world where visual content dominates, the need for fast, efficient, and creative animation tools is growing. AniSora meets this demand by offering:

  • Open-source accessibility: Available for everyone to use, modify, and improve.
  • High-quality output: Based on massive datasets of professionally produced anime.
  • Advanced capabilities: Like frame interpolation and image-to-video transformation.

AniSora democratizes anime video generation, allowing independent creators and developers to build projects once only possible in large studios.

Key Features of AniSora

1. Image-to-Video Animation

AniSora turns static anime-style illustrations into smooth video animations. Simply provide an image, and AniSora generates temporally coherent video frames that bring it to life.

2. Frame Interpolation

Missing frames in your animation? AniSora can fill in the gaps with its frame interpolation feature, making your videos more fluid and professional.

3. Region-Based Control

Using a unique spatiotemporal masking module, AniSora lets you animate only specific parts of the image. Want to animate just the character’s hair or eyes? You can.

4. Style Consistency

Thanks to its large and stylistically diverse training set, AniSora maintains high consistency in anime styles across frames.

5. Evaluation Benchmarks

AniSora includes a robust benchmark suite with 948 clips across various animation styles and motions, helping researchers evaluate performance in detail.

How to Use AniSora

Using AniSora is straightforward for developers and creatives alike. Here’s how to get started:

  1. Install AniSora: Clone the GitHub repository and set up the environment.
  2. Provide Input: Input an anime-style image or a series of frames.
  3. Configure Parameters: Choose animation length, motion patterns, or regions to animate.
  4. Generate Video: Run the model and review your output.
  5. Refine: Adjust input or masking for more control and re-render.

Use Cases for AniSora

Limitations to Consider

  • Hardware Requirements: Needs a capable GPU to process animations effectively.
  • Learning Curve: Advanced users will benefit most; some experience with ML tools is helpful.
  • Anime-Only Focus: Optimized for anime-style visuals, not general-purpose video.

AniSora in Action

Imagine uploading a single frame of your hand-drawn character and watching AniSora generate a full motion scene — blinking eyes, swaying hair, subtle expressions. That’s the power of AniSora. The tool not only accelerates the creative process but also ensures visual coherence and professional quality.

Creators on platforms like YouTube, TikTok, and Bilibili have started using AniSora for:

  • Short anime skits
  • Animated intros and outros
  • Game trailers
  • AI-assisted storytelling
