Show HN: Free Online Video Editor Powered by FFmpeg (Runs in the Browser) (sora2video.us)

I built a simple, free online video editor that runs entirely in your browser using FFmpeg compiled to WebAssembly.

No installs, no uploads, no server load — the processing happens locally, so your videos never leave your machine.

Currently supported: • Trim/cut clips • Adjust playback speed • Export locally (MP4) • Privacy-safe (client-side only)

It’s surprisingly fast, and works well for: • Social video edits • Quick meme/training clips • Micro-content workflows • When you don’t want to open Premiere/FCP
