Capture a product walkthrough, presentation or reproducible bug report without uploading the recording to YTSave.
The browser permission chooser supplies the selected display stream; MediaRecorder encodes supported WebM media into bounded in-memory chunks.
Choose one browser tab, enable tab audio if needed, record the demonstration and download the resulting WebM file.
