Animated LED Screensavers from GIFs: Simple Maker & Exporter

What it does

Converts animated GIFs into LED-style screensavers by mapping GIF frames to a low-resolution LED matrix, applying pixelation, color palette reduction, and export options so the result runs as a screensaver on desktop or as a standalone looping video.

Key features

• GIF import: Accepts animated GIFs (multi-frame) and common video formats.
• Pixelation / matrix size: Choose target LED resolution (e.g., 16×16, 32×32, 64×32).
• Color reduction: Limit colors to match LED palettes (monochrome, RGB, custom).
• Effects: Brightness/contrast, dithering, frame blending, scanline or glow.
• Timing control: Adjust frame rate, loop behavior, and per-frame delays.
• Preview: Real-time preview at target matrix size with export preview.
• Export options: Native screensaver format (where supported), animated PNG/video (MP4/WebM), sprite sheets, or a simple executable/HTML5 canvas player for cross-platform use.
• Optimization: Frame trimming, keyframe detection, and compression for smaller output files.

Typical workflow

1. Load GIF (or video).
2. Set LED matrix dimensions and color mode.
3. Adjust effects and timing.
4. Preview and tweak.
5. Export as screensaver file or web player.

Best use cases

• Desktop customization (Windows/macOS screensavers).
• Physical LED matrix testing/emulation.
• Background loops for kiosks or displays.
• Quick exports for social sharing (short video or GIF).

Limitations & tips

• Very detailed GIFs lose clarity when downscaled; prefer high-contrast source images.
• Reduce palette to avoid color banding and use dithering for smoother gradients.
• For long GIFs, trim unnecessary frames to keep screensaver size reasonable.

Example exports

• 32×32 RGB screensaver (.scr on Windows via bundled player)
• HTML5 canvas player with embedded frame data for easy cross-platform use
• MP4 loop for sharing or use as a simple screensaver on platforms without .scr support
