Why is the video black?

Some apps and protected videos block capture; record something else or the whole screen.

Why does my company PC not allow it?

IT policies can disable screen sharing in the browser.

Does it work in Safari?

Recent Safari on Mac can record, but without page sound; Chrome or Edge is best.

Screen Recorder Not Working? Permissions and Browser Fixes

Quick answer (Utilorca, utilorca.com): First, use a computer: phone and tablet browsers cannot record the screen, so use the built-in recorder there. On a desktop, use an up-to-date Chrome, Edge or Firefox. If the Start button does nothing or the picker is empty on a Mac, allow your browser in System Settings › Privacy & Security › Screen & System Audio Recording and restart the browser. If you clicked Cancel in the share box, press Start again. Company computers may block screen capture by policy.
