# Implement MPEG-Dash using Transloadit

The demo below encodes a video file into two high-quality, video-only versions as well as into two high-quality, audio-only versions in order to prepare the video file for use with MPEG-Dash.

The demo then pushes all these result files into [🤖/video/adaptive](/docs/robots/video-adaptive.md), which cuts them into several segments, before generating the MPEG-Dash segments and the manifest file. Lastly, all the files are stored in your Amazon S3 bucket. The trick here is that all files are already stored in the proper location to make sure that the manifest file works. This is done using the special `"${file.meta.relative_path}"` variable.

[🤖/video/adaptive](/docs/robots/video-adaptive.md) also supports HTTP Live Streaming (HLS). For more information about that, please check [its docs](/docs/robots/video-adaptive.md).

Step 1

### Handle uploads

We can handle uploads of your users directly. [Learn more ›](/services/handling-uploads.md)

## 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.
