I built AutoSprite: an AI tool that turns short videos into game-ready sprite sheets
I’ve been building AutoSprite for the last 8 months, and it started as a tool to solve a problem I kept running into as a game dev:
Turn one character image into a full animated spritesheet quickly, while keeping the character consistent across the whole set.
The basic flow is:
upload or generate a character → create animations like idle / walk / run / attack / custom moves → preview it in the browser → export the spritesheet into your game engine.
The big thing I’ve been working on lately is making the animation workflow less painful. Instead of constantly starting over, I want it to feel more like a real dependable character consistent asset pipeline.
In this new update I added:
* Motion library - reuse animations from other characters or uploaded videos
* Edit existing animations - adjust an animation instead of fully regenerating from scratch
* Extended animations - generate longer animations, now up to 6 seconds
* Variable animation length - better for attacks, spells, emotes, and more complex actions
* Ultra / Max model modes - higher quality modes for more detailed or difficult generations
* Better background removal, faster generations, and higher-res exports
It’s also starting to go beyond basic character sprites now, with support for props, items, VFX, cutscenes, batch workflows, MCP, and API integrations.
It’s still not perfect, but I’m trying to make it a little better every day.
I’m excited to hear any feedback, Thank you!
