# Live Event Captioning

By using the software OBS, you can caption your live event using Zip Captions so that the captions are overlayed on your projections and on video shown on your screen. 

There are a few ways to set this up.

Install the PWA version of Zip Captions using these instructions. 

Please make sure that your browser supports installation of PWA's by [visiting this page](/getting-started/supported-browsers.md).

1. Open the PWA on your computer from the Applications Menu
2. Minimise the toolbar by clicking the arrow

{% tab title="Simple Method OBS" %}
Using Websockets in OBS you can simply connect Zip Captions and OBS together. You can then livestream this to Twitch or to YouTube Live and turn on the captions on your feed. This is the same method that can be used for&#x20;

{% embed url="<https://zip-captions.gitbook.io/zip-captions/streaming-captions/captioning-with-obs>" %}
{% endtab %}

{% tab title="OBS Complex" %}
You can use the OBS Browser Source to capture a broadcast stream.&#x20;

<table data-card-size="large" data-view="cards"><thead><tr><th></th><th></th><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>OBS Application Source</strong></td><td>This allows you to capture a window on your desktop and chromakey it.</td><td></td><td><a href="/pages/cbuepqptagpKkwtXc4aU">/pages/cbuepqptagpKkwtXc4aU</a></td></tr><tr><td><strong>OBS Browser Source</strong></td><td>This allows you to capture captions from an inbuilt browser window in OBS.</td><td></td><td><a href="/pages/vWU1eXzxvHIwS2soGcdQ">/pages/vWU1eXzxvHIwS2soGcdQ</a></td></tr></tbody></table>
{% endtab %}
{% endtabs %}

For all live event captioning, you can always choose to broadcast your captions to attendees by following the instructions on the [Broadcasting Your Captions to Others](/streaming-captions/broadcasting-your-captions-to-others.md) page.&#x20;
