# Split your webcam and screen for just the demo

> Ask the Tella Agent in the Tella editor to use a side-by-side layout for the demo and full camera for the intro. It reads your transcript to find where the demo starts and ends, then adds a Side-by-Side layout section for that range. The rest of the clip keeps its base layout.

## How do I put my webcam and screen side by side for just the demo part of a video?

Ask the [Tella Agent](https://www.tella.com/agent) in the Tella editor to use a side-by-side layout for the demo and full camera for the intro. It reads your transcript to find where the demo starts and ends, then adds a Side-by-Side layout section for that range. The rest of the clip keeps its base layout.

## Prompt to start from

```text
Keep my intro and wrap-up on full camera. From "let me show you the dashboard" until "that's the demo", use Split Left 50/50 with my camera on the left. Use a smooth transition in and a hard cut back.
```

## More prompts

### Sales engineer follow-up

```text
Logistics prospect follow-up. Keep full camera for the first 30 seconds. When I open the shipment tracking screen, switch to Split Right, app on the left. Return to full camera when I get to next steps.
```

### Developer tools demo

```text
CLI demo. Keep full camera for the intro. For the terminal part, use Split Right Small so the terminal stays visible, then screen only while I scroll logs. Save the split as a favorite called Dev demo split.
```

## How to do it in Tella

1. Open a recording made in Tella with both screen and camera.
2. Open the Tella Agent in the right sidebar, or press Shift + S.
3. Say where the demo starts and ends and which side your camera goes.
4. Drag the section's edges in the Layout timeline, or ask the agent to adjust.

## Good to know

- Needs a paid plan or the 7-day trial. Messages use your workspace's credits.
- The 50/50 style crops your screen to its half. In landscape, the regular or overlap style keeps the whole screen visible.
- Portrait and square videos stack the split top and bottom, and only offer the 50/50 style.
- Layout sections must be at least 0.2 seconds long.

## Questions people ask

### Can I make a split-screen layout from a video I uploaded?

No. Tella gets an uploaded video as one combined track, so it can't place your camera and screen separately. You can still use Punch-in, a Media layout or Cut out.

### Can I reuse the same split layout in other videos?

Yes. In Tella, open Customize layout, adjust the Side-by-Side preset, name it and click Save under Save as favorite. It appears in the Layout picker's Favorites tab for other screen-and-camera clips.

### Can Claude or ChatGPT make the split-screen edit through Tella's MCP server?

Yes. Once connected to Tella's [MCP server](https://www.tella.com/mcp), [Claude](https://claude.ai/directory/tella) or [ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6a7026f78434819186579d93d20ab38b?open_in_app) can call add_layout with a side-by-side layout, camera position, start time and duration, so only the demo range changes.
