About the Video Recorder

Recording from a camera in a browser tab is genuinely useful for the short things nobody wants to open an application for: a introduction for a course, an answer to a question that is quicker to say than to type, a message to somebody who is asleep in another time zone, a piece to camera for a form that wants a video.

What it should not involve is a website receiving that footage. A video of your own face, recorded in your home, is about as personal a file as most people ever make, and the ordinary arrangement — record in a tab, footage goes to a server, download it back — asks you to trust a company with it for no reason at all. Here the recording is written into this tab's memory and appears in the file list on this page. Nothing is transmitted.

The preview shows what is being captured while it records, which catches the two mistakes everyone makes: the wrong camera selected, and a framing that cuts off the top of your head. Microphone audio is captured alongside the picture by default.

The result arrives as a WebM file in most browsers, which is what the browser's own recorder produces. Choosing MP4 in the save options converts it on the way out, which is worth doing if the recording is going anywhere near a piece of software older than about 2015.

Because the recording lands in the file list like any other file, everything else here applies to it. The first four seconds of you reaching for the button can be trimmed off. The result can be compressed before it is emailed. If the camera mirrored you and the writing on your shirt is backwards, the flip tool fixes it.

How to use it

  1. 1Press record and allow the camera when the browser asks.
  2. 2Check the preview — right camera, sensible framing — before you say anything.
  3. 3Press stop, and the recording appears in the list on this page.
  4. 4Save it as MP4, or trim and compress it here first.

Questions

Where does the video go?
Into this tab's memory, and then into the file list on this page. It is not sent anywhere and no account is involved.
Why is it a WebM file?
That is what most browsers' recorders produce. Choose MP4 in the save options and it is converted before you download it.
Can I choose which camera?
The browser decides, usually offering a picker the first time you allow access. Changing the default camera in your system settings is the reliable way to switch.
Why is my recording mirrored?
Front cameras show and often save a mirror image. Run the result through Flip Video to put any writing the right way round.
