General Questions
What is AutoSprite?
AutoSprite is an AI-powered tool that generates game-ready spritesheets from a single character image. You upload one picture, and AutoSprite creates complete animation sets (idle, walk, run, jump, attack) that you can use in any game engine.
What file formats do I get?
You receive:
- PNG spritesheet - All animation frames in a grid
- JSON atlas - Frame positions, sizes, and animation timing data
These formats work with Unity, Godot, Phaser, GameMaker, RPG Maker, and most other game engines.
How long does generation take?
Each animation takes approximately 30-60 seconds to generate. A full character with 5 animations typically completes in 3-5 minutes.
Credits & Pricing
How does the credit system work?
Credits are spent when you generate, not when you export. The price of an animation comes from the video tier you pick on the Animate tab:
turbo(2s) — 5 credits, the free-plan defaultpro(4s / 6s) — 10 / 15 creditsultra(1–6s) — 10 credits per secondmax(4s / 6s) — 35 / 53 credits
An isometric 8-direction pack (recommended) costs 15 credits for all eight directions in one render; individual isometric directions are billed at the tier price per direction. See Credits & Pricing for the full cost list.
What's the difference between 4 and 6 seconds on the Pro tier?
Clip length is how many seconds of motion the AI generates — it isn't a smoothness or speed setting, and it doesn't change your character's stride length (that comes from the motion prompt).
The catch: your spritesheet samples a fixed number of frames out of the clip. At 64 frames, a 4s clip gives ~16 sprites per second of motion while a 6s clip gives ~10.7 — the same sprites spread across 50% more motion. So 6s at the same frame count looks choppier, not smoother.
What 6s buys you is more complete motion: the model isn't compressing anticipation, strike and recovery into 4 seconds. Use it for one-shot actions like attacks, jumps and spell casts, and raise Frames to 64 or MAX when you do. Stick to 4s for looping cycles like idle, walk and run.
Do I get free credits?
Yes! New accounts start with 15 free credits - enough to create about 3 complete spritesheets. You also earn 3 bonus credits each day you log in.
What happens when I run out of credits?
You can buy a one-time credit pack (100 credits for $5, never expires) or upgrade to a subscription:
- Starter ($12/month) — 500 credits/mo, unlimited exports, all four video tiers, Advanced Mode, API and MCP
- Pro ($29/month) — 1500 credits/mo, 25 free redos, credit rollover, higher queue priority
- Studio — custom pricing, team workspaces and unlimited redos
Almost every feature unlocks at the first paid tier — the plans mainly differ in credits, redos and queue priority.
Technical Questions
What image sizes work best?
- Minimum: 256x256 pixels
- Recommended: 512x512 to 1024x1024 pixels
- Maximum: 2048x2048 pixels
Higher resolution inputs generally produce better results.
Can I use AI-generated characters?
Yes! AutoSprite works great with characters from Midjourney, DALL-E, Stable Diffusion, or any other source. The character just needs to be clearly visible against the background.
Why are my animations blurry or distorted?
Common causes:
- Low-resolution input - Use at least 512x512 images
- Complex backgrounds - Crop closer to the character
- Too much detail - Simpler designs animate more consistently
- Output settings - In Spritesheet settings on the Animate tab, raise Resolution to 512 or MAX, turn on Ultra background removal, and add sharpening
- Too few frames for a long clip - A 4s or 6s clip sampled at 25 frames reads as choppy. Use 64 or MAX.
Can I edit the spritesheet after export?
Most edits are easier before you export. In AutoSprite you can use Redo to regenerate a first frame, last frame or the video with a new prompt, Edit Animation to restyle or extend a clip, the Frame Strip Editor in Advanced Mode to work frame by frame, and Wardrobe to change your character's outfit.
The exported PNG is also a standard image file, so you can open it in any image editor if you need to.
Troubleshooting
How does AutoSprite ensure character consistency?
AutoSprite maintains character consistency by using your single input image as the source of truth for every animation frame. The AI preserves your character's design, proportions, colors, and details across idle, walk, run, jump, attack, and custom animations.
My character looks different in the animation
AutoSprite maintains character consistency, but AI generation can sometimes alter minor details. Tips for maximizing character consistency:
- Use simpler character designs with clear silhouettes
- Avoid very complex outfits or accessories
- Use high-resolution input images (512x512 or larger)
- Check the "character view" matches your input
The animation speed is too fast/slow
You can adjust animation speed in the preview player. This setting exports with your JSON file, or you can override it in your game engine.
Background removal isn't working perfectly
Try:
- Using an image with higher contrast between character and background
- Using a PNG with transparent background
- Selecting "Ultra" quality in background removal settings
