Why this tool is useful
Create a quick camera clip or spoken explanation when a private local download is more appropriate than a cloud recording service.

Record video from a permitted camera locally with an optional microphone and no media upload.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
Create a quick camera clip or spoken explanation when a private local download is more appropriate than a cloud recording service.
After explicit camera permission, the page passes the live MediaStream directly to the browser MediaRecorder implementation.
Select the preferred camera, record a short introduction and save it as the MIME type supported by the current browser.
Browser capability and explicit capture permission are checked before recording starts; unsupported sources fail without producing a file.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
