Sprite Lab V0.2🧪 - Universal 2D Sprite Sheet Generator

Sprite Lab is the ultimate tool for indie developers who want to transform video animations into optimized 2D Sprite Sheets. Perfect for Godot, Unity, and Unreal Engine.

Key Features:

• Smart Chroma Key: Remove background colors with an eyedropper.
• Precise Recut: Select the exact frames for your loop.
• Auto Grid: Instant rows/columns calculation.

New in Version 0.2

• Manual Pixel-Perfect Crop: Draw your selection directly on the viewer. Our new robust coordinate mapping ensures 100% precision with no offsets.
• Bilingual Interface: Switch between English and Spanish instantly with one click.
• Open Source & Privacy: 100% Local processing. No data collection. No cloud. Just your machine and FFmpeg.

The Use Case

I built Sprite Lab because I’m a solo developer working with AI video generators (Grok/Runway/Luma) and Blender renders. These tools output MP4/AVI files, and manually extracting frames to create a balanced sprite sheet is a nightmare. This tool automates that specific workflow.

Quick Start Tutorial

• Load: Drag your video directly into the app or use the "Load Video" button.
• Trim: Use the range slider to define the start and end of your animation loop.
• Clean: Activate Chroma Key, use the Eyedropper, and adjust the tolerance.
• Export: Hit "Export PNG" and get your assets!

A Gift for the Community

This tool was born to simplify the tedious process of manual frame extraction. We want to empower indie developers and artists to bring their animated visions to life faster than ever.

We need your help! This is a work in progress. Please, download it, break it, and tell us what you think! Your feedback will drive the new versions features.
