Why do ToolCix GIFs look sharper than basic converters?

ToolCix builds a per-clip 256-color palette using FFmpeg palettegen and paletteuse filters instead of a generic fixed palette, avoiding banding.

What FPS and width keep GIF file sizes small?

Using 10 to 12 FPS at 480px width produces smooth documentation and social GIFs while keeping file sizes manageable.

Do generated GIFs loop automatically?

Yes, exports are encoded with infinite looping (-loop 0) so they replay seamlessly in Slack, GitHub, Notion, and browsers.

Why is clip duration capped at 30 seconds?

GIF is an uncompressed-frame format; long clips quickly exceed browser memory and create huge files. Trimming to 3–15 seconds gives the best results.

Creating Crisp Animated GIFs With Custom Color Palettes

The GIF format supports only 256 colors per frame, which causes grainy dithering when tools use a static web-safe palette. ToolCix analyzes the exact colors present in your trimmed video segment via FFmpeg's palettegen filter and maps every pixel with Lanczos scaling for sharp UI text and smooth gradients.

Optimizing GIFs for GitHub READMEs, Slack, and Docs

For software demos and support tickets, trim directly to the relevant 4-to-8-second action, select 10 FPS, and cap width at 480px or 640px. Your teammates get an instant looping visual without waiting for heavy video embeds.
