How it works

The video is recorded in real time by your browser: a 30-second clip takes 30 seconds.
The file type depends on the browser: MP4 on Safari and recent Chrome, WebM elsewhere (Instagram and TikTok take both through their apps, YouTube always).
For Reels and TikTok use vertical 9:16 and 15 to 60 seconds.

Everything happens on this device: no file is uploaded and nothing leaves the browser.
