# Generate a video from an image sequence

Transloadit allows you to generate a video from a set of images. The images are merged in the order of their filenames. You could, for example, call them `1.jpg`, `2.jpg`, etc. and they will be used in the correct order.

Alternatively you could also fixate the order by naming individual Steps:

```jsonc
{
  // ...
  "merged": {
    "robot": "/video/merge",
    "use": {
      "steps": [
        {
          "name": ":original",
          "as": "audio",
        },
        {
          "name": "resized_chameleon",
          "as": "image",
        },
        {
          "name": "resized_prinsengracht",
          "as": "image",
        },
        {
          "name": "resized_snowflake",
          "as": "image",
        },
      ],
    },
  },
  // ...
}

```

## So many ways to integrate

Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.

#### Bulk imports

Add one of our [import Robots](/services/file-importing.md) to acquire and transcode massive media libraries.

#### Handling uploads

We are *the* experts at reliably [handling uploads](/services/handling-uploads.md). We wrote the [protocol⁠](https://tus.io/) for it.

#### Front-end integration

We integrate with web browsers via our next-gen file uploader [Uppy⁠](https://uppy.io/docs/guides/uppy-transloadit/) and SDKs for Android and iOS.

#### Back-end integration

Send us batch jobs in any server language using one of our [SDKs](/docs/sdks.md) or directly interfacing with our [REST API](/docs/api.md).

#### Pingbacks

Configure a [notify\_url](/services/content-delivery.md) to let your server receive transcoding results JSON in the `transloadit` POST field.

#### On-demand

Use our [Smart CDN](/services/file-importing.md) to adapt files on-demand and stream them directly to your users.
