# Choose what to record

> Choose your camera, screen, microphone, and camera preview framing before recording in Tella.

Before you hit record, you can choose exactly what Tella captures. Use the camera, microphone, and screen sharing controls in the recorder to set up the right combination for your video.

## Recording combinations

* **Screen + camera + voice** — the most common setup for demos and walkthroughs. Your camera appears as an overlay on your screen recording.

* **Screen + voice** — a screen recording with voiceover, without showing your face. Toggle the camera off to use this mode.

* **Camera + voice** — a talking-head video, great for intros or personal messages.

* **Screen only** — a silent screen capture, useful for short demos you plan to narrate later or speed up as a timelapse. Toggle both the camera and microphone off.

## How to toggle camera and microphone

In the recorder, use the **camera** and **microphone** buttons to turn each one on or off before or during recording.

* **Camera button** — toggles your webcam on or off. Turn it off to record without being on camera.

* **Microphone button** — toggles audio capture on or off. Turn it off for a silent recording.

* **Dropdown arrows** — click the arrow next to each button to switch between available cameras or microphones.

<Tip>
  You can toggle your camera and microphone between clips without leaving the recorder. For example, record an intro clip with your camera on, then turn it off for a screen recording clip.

## Check your camera framing

The camera preview fills its frame by default, which can crop the edges of the image. To check everything your camera sees before recording:

1. Turn on your camera.
2. Click the round **Show full camera** button next to the **mirror camera** button. The complete camera view fits inside the preview, with black bars when needed.
3. Click **Fill the frame** to return to the cropped preview.

Tella remembers your choice on the current device and uses it in camera-only, screen and camera, and slides and camera modes.

<Note>
  Fit and fill only change the recorder preview. Tella still captures the full camera track, which you can arrange with [layouts](/docs/help/editing/use-layouts) in the editor.
</Note>

## How to share your screen

1. Click **share screen** in the recorder.

2. Choose what to share — your entire screen, a specific window, or a browser tab.

3. Confirm your selection. You'll see a preview of the screen you're about to record.

If your camera is on, it will be recorded alongside your screen as a separate video track. In the editor, you can then use [layouts](/docs/help/editing/use-layouts) to control how the camera and screen are arranged in your final video.

<Note>
  Layouts are an editor feature — they don't affect what gets recorded. Everything you toggle on in the recorder is captured as a separate track, and you choose how to arrange those tracks later in the editor.
