# Set a background video

Set or update the background video of Flat Window Template

{% hint style="danger" %}
**This tutorial requires FlatWindow Template**
{% endhint %}

This FlatWindow template downloads the video from your host.

If video in the host has a different size than the downloaded one, then the video in the host is downloaded again (for updating the video).

The video needs to be located under ***<https://yourhost.com/GameLauncher/News/Release/>***

### Uploading a video in your host

{% hint style="warning" %}
The video needs to be an **mp4 file**

The video name needs to be ***Video.mp4*** (caps sensitive)

**We recommend to compress the video to be 50 MB or less and with duration of less than 1 minute.&#x20;*****(There is no limit here, but it's annoying to download a 1 GB video, and most of your users never see more than 20 seconds of the video).***
{% endhint %}

1. Upload your ***Video.mp4*** in the ***GameLauncher/News/Release*** of your host

**And that's all!**&#x20;

{% hint style="info" %}
If you want to **update your video, you just only need to replace it in your host.**&#x20;

**Game Launcher will automatically recognize the change and re-download the new video.**
{% endhint %}

<mark style="color:green;">**You now can run it to test it!**</mark>
