Video & Media Tools

Editing video inside a browser tab is possible now, and these posts are an honest account of how — and of where it stops.

The technical core is FFmpeg compiled to WebAssembly, running in your tab. The posts explain what that buys you (no upload, no queue, no watermark) and what it costs (the whole file has to fit in browser memory, and encoding is slower than a native app because it is a single-threaded WASM build, not your CPU’s full capability). A 30-second clip trims in seconds. A 500 MB export is a laptop job and a coffee break, and no tool on this site will pretend otherwise.

Also covered: why trimming without re-encoding is instant and trimming with re-encoding is not, what a codec and a container actually are (MP4 is not a codec), why blurring a face in video means tracking it across frames rather than blurring once, and how screen recording gets audio and video out of sync.

For creators, teachers recording tutorials, and journalists handling footage that must not touch a cloud service. The Video Studio is next door.
