MidCozyShip It

FFmpeg WASM + WebCodecs in browser, but only useful if you use WigglyPaint.

Strengths
  • FFmpeg WASM + WebCodecs pipeline runs entirely client-side with no server costs.
  • Solves the author's actual workflow pain — manual FFmpeg command mangling eliminated.
Weaknesses
  • Extremely narrow audience — only WigglyPaint users need this specific GIF-to-video flow.
  • FFmpeg CLI already handles this; browser convenience doesn't add unique capability.

Post Description

Been trying out WigglyPaint[1] lately to flesh out my creative side. I started drawing a series of images, and wanted to combine them into a video to post into social media.

The first iteration I did was manually mangling FFmpeg commands to loop GIFs over n seconds, before combining them into a video. After that I thought, I might as well make a web application to help make this easier.

Ironically, the videos I created in my Firefox Windows appears to be unplayable, which prompted me to go full circle, by importing a FFmpeg WASM to fix the file.

But it was definitely interesting to see how the JS code work to splice GIFs into image data, replaying it over a canvas, which then feeds to a WebCodec. GitHub link is in [2] if you are interested to see the source code. Cheers!

Video Compressor – 10x Faster via Dual-Engine (WebCodecs/WASM)

This runs entirely in the browser and routes encoding through the WebCodecs path for GPU-accelerated speed, falling back to a WASM engine when needed — that dual-engine approach is the real hook. The UI gives sensible presets (Discord, WhatsApp, email) and clear privacy messaging, but the pitch leans heavily on speed claims without visible cross-browser compatibility or quality/bitrate tradeoff details.

Pablituuu – Web Video Editor with AI Highlights (WebGL, FFmpeg WASM)

Running FFmpeg in-browser combined with WebGL-accelerated rendering and a Fabric.js timeline is a concrete technical win — it actually removes the need for a heavy server backend. The Gemini-powered 'AI Analytics' highlight detection is the feature people will demo first, but the real risk is memory and export performance with large assets in the browser; that's the engineering problem this project needs practical answers for.
