Record a video in three steps
- Allow camera and microphone access when your browser asks.
- Pick your devices and quality in the settings panel: which camera, which microphone, resolution, quality and file format.
- Press the red Record button. Use Pause to skip a section and Stop to finish. The recording appears in the gallery straight away, ready to play back and download.
On a keyboard, Space starts and stops recording and P pauses and resumes.
How big will my video be?
The recorder sets the video bitrate from the resolution, frame rate and the quality you choose. These are the approximate file sizes per minute at 30 fps, including audio:
| Resolution | Standard | High | Maximum |
|---|---|---|---|
| 1280 × 720 (720p) | ≈ 11 MB | ≈ 22 MB | ≈ 38 MB |
| 1920 × 1080 (1080p) | ≈ 24 MB | ≈ 48 MB | ≈ 85 MB |
| 3840 × 2160 (4K) | ≈ 94 MB | ≈ 188 MB | ≈ 188 MB |
At 4K, High and Maximum reach the recorder's 25 Mbit/s ceiling, so they come out the same size. Real files are often smaller, because a talking head with a still background compresses much better than a moving scene. As a rule of thumb, High at 1080p is the right choice for tutorials and presentations; Standard is fine for quick messages; Maximum is for footage you'll edit afterwards.
WebM or MP4?
The recorder uses your browser's built-in video encoder, so the formats on offer depend on your browser. The settings panel only lists formats your browser can actually produce - we never upload a recording to convert it.
| Format | Produced by | Plays in |
|---|---|---|
| WebM (VP9 + Opus) | Chrome, Edge, Opera, Firefox | All modern browsers, VLC, YouTube, most editors |
| WebM (VP8 + Opus) | Chrome, Edge, Opera, Firefox | Same as above; slightly larger files than VP9 |
| MP4 (H.264 + AAC) | Safari; recent Chrome and Edge | Everywhere, including older phones, Windows Media Player and QuickTime |
Choose MP4 if it's offered and you plan to send the video to someone who might open it in older software. Choose WebM VP9 for the best quality at a given size.
Need MP4 but only WebM is offered?
Upload the WebM file directly - YouTube, Google Drive, Vimeo and most social networks accept it. If you need MP4 for a specific app, free desktop tools such as VLC or HandBrake can convert it on your own computer.
Recording with sound
Turn Record sound on in the settings panel and choose a microphone. Headsets, USB microphones and webcams with built-in microphones all appear in the list. A live level meter shows whether the microphone is picking you up before you press Record - if it doesn't move when you speak, choose a different device or run the Microphone Test.
To record video without sound, turn Record sound off before you start.
Pause instead of starting over
Pause stops recording but keeps the file open. Press Resume and recording continues in the same file, with no gap and no need to join clips afterwards. It's ideal for tutorials: pause while you set up the next step, then carry on.
Long recordings
Recordings are assembled in your device's memory until you download them. There's no time limit set by us, but memory is finite:
- Computers handle long recordings comfortably; an hour at 1080p High is around 3 GB.
- Phones and tablets have less memory available to a browser tab. Keep phone recordings shorter, use 720p, and download as soon as you finish.
- Don't close the tab or let the phone lock before downloading. If Keep media on this device is on, recordings are also saved in your browser's local storage and survive a reload.
Filters while recording
Every filter and adjustment you apply is recorded into the video, including background blur and replacement. You can even change the filter during the recording - the change is captured at that moment. See Camera Filters for what each look does.
Where does the recording go?
Nowhere but your device. The video is encoded by your browser, held locally, and saved to your Downloads folder when you press download. We never receive it. Read the privacy page for the details.
