# Content and Uploads

{% stepper %}
{% step %}

### Create content

Create a content item (optionally tied to a channel).

**GraphQL:**

```graphql
mutation {
  createContent(
    input: {
      hints: [{ type: FEATURE, containsAds: NO }]
      metadata: {
        title: "My Video"
        summary: "Video description"
      }
    }
  ) {
    id
    metadata { title }
  }
}
```

**MCP:** Use the `create_content` tool with `title`, `summary`, and `type` (e.g. FEATURE). The response includes the content `id` (DID).

Save the returned `id` (e.g. `did:rad.live:content/feature/<id>`); you need it for the next steps.
{% endstep %}

{% step %}

### Create an ingestion session (TUS)

Request a resumable upload session for the content. You get an **endpoint** to POST the file to.

**GraphQL:**

```graphql
mutation {
  createContentAsset(
    id: "did:rad.live:content/feature/<id>"
    input: {
      filename: "my-video.mp4"
      size: 12345678
      video: { hint: NONE }
    }
  ) {
    id
    endpoint
    metadata { filename originalFilename }
  }
}
```

**MCP:** Use `create_content_asset` with `contentId` (the content DID), `filename`, `size`, and optional `hint` (e.g. NONE, PORTRAIT, EQUIRECTANGULAR).

The response includes `endpoint` (e.g. `https://api.rad.live/ingestion/<session-id>` or your TUS upload URL).
{% endstep %}

{% step %}

### Upload the file

POST the file to the **endpoint** from step 2:

* **Headers:** `Authorization: Bearer <api-key>`, `Content-Type: multipart/form-data`
* **Body:** The file (multipart/form-data)

Resumable uploads use the TUS protocol; the ingestion endpoint may point to a TUS server. Follow the session instructions returned by `createContentAsset` / `create_content_asset`.
{% endstep %}

{% step %}

### Submit for processing

After the file is uploaded, submit the content for transcoding. Use the **same filename** you passed to `createContentAsset` as `assetName`.

**GraphQL:**

```graphql
mutation {
  submitContentForProcessing(
    id: "did:rad.live:content/feature/<id>"
    input: {
      assetName: "my-video.mp4"
      layout: LANDSCAPE
      encoder: RAD_ENCODER
    }
  ) {
    content { id }
    job { id status progress }
  }
}
```

**MCP:** Use `submit_content_for_processing` with `contentId`, `assetName`, and optional `layout`, `encoder`, `enhance`.

You get a **TranscodeJob** with `id`, `status`, and `progress`. Poll the content’s `transcodeJob` (or the job id) until the job is complete.
{% endstep %}

{% step %}

### Output assets

When transcoding is complete, the content’s `outputAssets` field is populated. Query it via GraphQL:

```graphql
query {
  me {
    channel {
      features(limit: 10, start: 0) {
        id
        metadata { title }
        outputAssets {
          encoderType
          video { hls download preview }
          audio { download }
          images {
            thumbnails { urlFormat count }
            videoThumbnails { urlFormat count }
          }
          subtitles { srt vtt }
        }
      }
    }
  }
}
```

* **video** — `hls` (streaming), `download` (MP4), `preview` (may be null for some encoders)
* **audio** — `download`
* **images** — Thumbnails are described by `ThumbnailSet`: `urlFormat` (string with placeholder) and `count`. Replace the placeholder in `urlFormat` with zero-padded indices: `XXXXXXX` = 7-digit 0-based (MediaConvert); `XX` = 2-digit 1-based (Rad Encoder).
* **subtitles** — `srt` and `vtt` URLs (null for MediaConvert; present for Rad Encoder).

See [Schema reference — Output assets and thumbnails](/rad/rad-tv-developer-api/graphql/schema-reference.md#output-assets-and-thumbnails) for details.
{% endstep %}

{% step %}

### Publish (optional)

To make the content public:

**GraphQL:** `publishContent(id: "did:rad.live:content/feature/<id>")`\
**MCP:** `publish_content` with `id` (content DID).

To revert to protected: `unpublishContent` / `unpublish_content`.
{% endstep %}
{% endstepper %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.rad.live/rad/rad-tv-developer-api/content-and-uploads.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
