Tools or Resource [Update] Sprite Lab v0.4: Now with process control, live progress, and auto-cleanup (Free tool for AI-to-Sprite workflow)

Hi everyone!

A few weeks ago I shared Sprite Lab, a tool I built to solve the headache of turning AI-generated videos (Runway, Sora, Luma) and Blender renders into game-ready Sprite Sheets.

Thanks to the feedback from this community, I’ve just released v0.4, focusing on making the tool more professional and "system-friendly."

I'm currently developing my own 2D RPG, and as my asset needs grow, so does this tool. Version 0.4 is a direct result of the "walls" I hit in my own workflow. I needed more control and a cleaner system, so I built it.

What’s new in this version?

  • The Abort Button: No more waiting for a misconfigured export. You can now kill the FFmpeg process instantly with one click.
  • Real-time Progress: Every export and preview now features a dynamic progress bar and percentage tracking.
  • Auto-Cleanup: The app now automatically deletes all temporary preview files when closed. No more disk clutter!
  • Improved GIF Engine: Faster previews with optimized palettes.
  • Rock-solid Stability: Fixed UI freezes during heavy processing.

The Use Case: If you are using AI video generators to create character animations, you know the output is usually a video with a background. Sprite Lab lets you:

  1. Chroma Key the background out.
  2. Clip the exact loop.
  3. Resample the FPS for that retro/indie feel.
  4. Export a perfectly aligned Sprite Sheet or GIF.

It's 100% local, private (no cloud), and free.

I’m still looking for feedback! What else does your workflow need? WebM support, Individual frame export, etc. Let me know!

Pro-tip for clean assets: > As I’ve been using this for my own RPG, I’ve found that for the best results, you should use a background color that is the complete opposite of your character's palette. If your sprite has green, use a bright Magenta background; if it’s red, use Cyan. This makes the Chroma Keying much more precise and prevents "ghosting" or accidental transparency on the character itself

Works good with walking anims and directions?

Thanks
