# Platform demo video

> Configure the YouTube demo video shown on the public landing page to help prospects understand the platform before signing up.

## What this is for

When prospects visit your white-label platform's landing page, they see a **demo video section** with a 20-minute platform deep dive. This video plays directly on the page and is designed to convert visitors into signups.

You choose which YouTube video appears by setting the `NEXT_PUBLIC_DEMO_VIDEO_ID` configuration value. This is a setup-level setting rather than a switch in the portal, so if you're self-hosting you'll set it in your configuration; otherwise ask Knotie support to update it for you.

***

## How it works

The landing page includes an animated section titled **"See How Easy It Is to Build Your Voice AI Empire"** that embeds a YouTube video. Visitors can watch it inline without leaving your page. The section also has a **Get Started** button that opens the signup modal.

The "See how it works" link in the platform hero section scrolls down to this video automatically.

## Configure the demo video

### Set the video

The setting to change is `NEXT_PUBLIC_DEMO_VIDEO_ID`, and its value is simply the **YouTube video ID** — the part after `youtu.be/` or `?v=` in a YouTube link. For example, if your video is at `https://youtu.be/ABC123xyz`, the value is `ABC123xyz`:

```
NEXT_PUBLIC_DEMO_VIDEO_ID=ABC123xyz
```

The default is the official Knotie AI platform overview video. Replace it with your own if you want a custom white-label demo. If you're not self-hosting, ask Knotie support to set this for you.

### Finding the YouTube video ID

1. Open the YouTube video you want to use.
2. Copy the URL from the browser address bar.
3. Extract the ID:
   * From `https://youtu.be/ABC123xyz` → ID is `ABC123xyz`
   * From `https://www.youtube.com/watch?v=ABC123xyz` → ID is `ABC123xyz`

## After changing the video

This setting is applied when the application is built, so the change only takes effect after the platform is **rebuilt and redeployed**. Simply restarting isn't enough. If Knotie support manages your hosting, they'll handle this for you.

***

## Hiding the demo video section

There's no on/off switch to hide the demo video section. If you'd rather it didn't appear, you can:

* Point the setting at an unlisted YouTube video of your choice, or
* Ask Knotie support to remove the section for you (this needs a code change by a developer).

***

## Troubleshooting

* **Video not showing up**
  * Confirm the setting was saved and the platform was rebuilt after the change.
  * Make sure the YouTube video ID is correct and the video is public (or unlisted).
* **Wrong video is showing**
  * Check that the new value was saved and the platform was rebuilt — the old video can linger until then.
* **"Video unavailable" inside the player**
  * The video owner may have turned off embedding. In YouTube Studio, make sure **Allow embedding** is turned on for the video.
