How this service works

Sprite tools: Turn an animation video or GIF (from Kling, Veo, Sora or a capture) into a sprite sheet: frames at your fps, background removed, every frame aligned to one box and pivot so it does not jitter, the best loop point, TexturePacker JSON, Godot SpriteFrames and a GIF preview. Full schema: https://rengi.dev/v1/sprite-tools/schema

Output

Returns a sprite sheet image with all frames aligned to a consistent bounding box and pivot point (to eliminate jitter), background removed, the optimal loop point identified, a TexturePacker JSON layout, a Godot SpriteFrames file, and an animated GIF preview of the result.

Example use cases

AI animation to game sprite

“I just generated a character run cycle in Kling — can you convert it into a sprite sheet at 24 fps, remove the background using AI, cap it at 48 frames, and export the Godot SpriteFrames file? Here's the video URL: https://example.com/run-cycle.mp4”

Pixel art GIF sprite sheet

“I have a pixel art GIF of a coin spin animation — convert it into a sprite sheet with nearest-neighbour scaling, keep the background, set the frame size to 64px, and give me the TexturePacker JSON layout.”

Looping idle animation from screen capture

“Here's a base64 WebM of an idle character animation I screen-captured — extract frames at 12 fps starting at 0.5 seconds, auto-remove the background, find the best loop point, and package it as a sprite sheet with a GIF preview.”

Endpoint

When to prefer

Choose this endpoint when you need to convert an AI-generated animation (from Kling, Veo, Sora, or similar) or a captured GIF/video into a game-ready sprite sheet with professional preprocessing — background removal, jitter-free frame alignment, loop detection, and direct export to TexturePacker or Godot formats — rather than doing raw frame extraction only. It is especially valuable when you need engine-compatible metadata alongside the image.

Side effects

Video too large or format unsupported — only MP4, WebM, MOV, GIF accepted
AI background removal limited to 24 frames maximum
maxFrames or fps combination exceeds limits (max 120 frames, max 60 fps)
Invalid or unreachable videoUrl returns an error
Base64-encoded video malformed or exceeds size limits
frameSize out of range (must be 16–1024)
Payment not provided or x402 payment fails
