Does SpriteGen upload my videos or art assets to any remote server?

No. SpriteGen runs 100% on the client side using your browser's WebGL, WebGPU, and WebAssembly capabilities. Your original game graphics, videos, and generated assets never leave your computer, ensuring absolute privacy and zero server latency.

How does SpriteGen detect seamless idle and run cycles?

SpriteGen uses a specialized frame-difference matrix algorithm that measures adjacent frame velocity and boundary seam divergence. It offers tailored presets for subtle idle breathing cycles (18~72 frames) and physiological bipedal run cycles (12~30 frames), ranking loop candidates by seam quality.

Which game engines are supported by SpriteGen sprite sheets?

SpriteGen exports standard horizontal sprite strips and packed atlases alongside structured JSON frame data. The exported files are directly compatible with Godot 4, Unity 2D Sprite Editor, RPG Maker, Cocos Creator, Phaser, and Raylib.

Will SpriteGen support AI Image-to-Video and Text-to-Video generation?

Yes! SpriteGen is expanding into AI character animation. Future releases will allow creators to generate action videos directly from character concept art (Image-to-Video) or text prompts (Text-to-Video) with fixed side-view cameras and clean backgrounds, feeding seamlessly into the sprite cutting pipeline.

4-Step Game Animation Workflow

1. Upload & Action Slicing

Scrub video timeline with sub-second accuracy to cut distinct clips (idle, run, slash) into named animation tracks.

2. Keyframe & Cycle Detection

Algorithmic detection of seamless idle breathing cycles and run cycles. Preview synced loop candidates instantly.

3. High-Precision Matting

Compute-saving matting only runs on confirmed frames. Advanced edge choke, feathering, and green despill filters.

4. Engine Atlas Delivery

Bake high-density sprite strips and packed atlases with pixel coordinate JSON for Godot 4, Unity, and RPG Maker.

🚀 AI GENERATION LAB · COMING SOON

Next-Gen AI Video & Asset Generation on spritegen.cc

We are expanding SpriteGen into a full-cycle generative game art platform. Soon creators can generate side-view animation videos directly from static concept art or natural language prompts, feeding seamlessly into our in-browser slicing studio.

🎨 Image-to-Video (图生视频) for Game Characters

Upload a single concept art, character turn-around, or pixel portrait. Our AI model animates it into smooth 24fps motion clips against pure white or green screen backgrounds.

✨ Text-to-Video (文生视频) Action Synthesis

Prompt character actions with strictly locked orthogonal side-view cameras (e.g. “Knight double slash with blue crescent energy arc”) ready for immediate sprite baking.

Frequently Asked Questions (FAQ)

What is SpriteGen (spritegen.cc)?

SpriteGen is an open browser-native 2D game animation studio and sprite sheet maker. It enables game developers to convert video footage into production-ready sprite sheets with automated loop detection, chroma key matting, and instant engine export.
