## Overview

`CometChatVideosBubble` renders the video attachment(s) of a media message with batch-aware styling. It is **self-extracting**: pass the SDK `message` and the bubble derives its attachments, caption, and alignment itself. The message list uses it automatically for video messages.

Key capabilities:

* **Adaptive grid layouts** — single video, 2-column, 2×2 grid, and overflow (+N) based on attachment count
* **Poster thumbnails** — auto-generated from the `thumbnail-generation` extension or first frame
* **Duration overlay** — displays video duration on each tile
* **Play icon overlay** — visual indicator on each video tile
* **Fullscreen viewer** — click any video to open in fullscreen player
* **Batch grouping** — rendered as one connected group when several media messages are sent together (handled by the [message list](/ui-kit/react/components/message-list#multi-attachment-batch-grouping))

## Usage

```tsx theme={null}
import { CometChat } from "@cometchat/chat-sdk-javascript";
import { CometChatVideosBubble } from "@cometchat/chat-uikit-react";

function VideoMessage({ message }: { message: CometChat.MediaMessage }) {
  return <CometChatVideosBubble message={message} />;
}
```

## Grid Layouts

The bubble automatically selects a layout based on the number of video attachments:

| Attachment Count | Layout         | Description                                  |
| ---------------- | -------------- | -------------------------------------------- |
| 1                | `single`       | Full-width single video with poster          |
| 2                | `grid` (2-col) | Side-by-side video tiles                     |
| 3                | `grid` (three) | 2-col grid with one spanning                 |
| 4                | `grid-2x2`     | 2×2 even grid                                |
| 5+               | `overflow`     | 2×2 grid with last tile showing "+N" overlay |

Each tile shows a poster thumbnail, play icon, and duration badge.
