# OBS Setup

How to add Battle Trade as a browser source in OBS Studio.

## Step 1: Add a Browser Source

In OBS, click the **+** button in the Sources panel and select **Browser**. Name it something like "Battle Trade Overlay".

## Step 2: Set the URL

Point it to your lobby's broadcast URL:

```
https://battle.fyi/broadcast/[your-lobby-id]
```

## Step 3: Configure resolution

Set the browser source to **1920x1080**. The broadcast view is designed for this resolution. For 4K displays, use the wall view at `/lobby/[id]/wall`.

## Step 4: Scene switching

Set up multiple OBS scenes for different moments:

| Scene          | View           | When                                      |
| -------------- | -------------- | ----------------------------------------- |
| Pre-show       | Stage view     | Before the battle starts, countdown timer |
| Active round   | Broadcast view | During live trading                       |
| Between rounds | Leaderboard    | Elimination announcements, standings      |
| Post-match     | Stage view     | Final results, winner reveal              |

## Tips

* The broadcast overlay is **transparent-friendly**. You can layer it on top of other content.
* All data updates in real time. No need to refresh the browser source.
* Use the admin panel in a separate window to control rounds and trigger volatility events while streaming.
* The commentator Cast view shows extra stats that aren't visible to spectators. Good for a second monitor.
