# Video Conversion

Each _Receiver_ service can convert an input video resolution to a different output resolution
(i.e. up-conversion or down-conversion). The processed video can be passed through to output standards
such as SDI, SMPTE ST 2022-6, or SMPTE ST 2110.

## Supported Conversions

The following output resolution conversions are supported. Frame-rate is preserved; conversions between
interlaced and progressive formats are supported where applicable.

| Input resolution | SD Output | 720p Output | 1080i Output | 1080p Output | 2160p Output |
| :--------------- | :-------: | :---------: | :----------: | :----------: | :----------: |
| UHD              |           |      ✔      |       ✔      |       ✔      |       ✔      |
| 1080p            |           |      ✔      |       ✔      |       ✔      |              |
| 1080i            |           |      ✔      |       ✔      |       ✔      |              |
| 720p             |           |      ✔      |       ✔      |              |              |
| SD               |     ✔     |             |              |              |              |

## Configuring Video Scaling

Video conversion is controlled using the **Video Scaling** option. It is also available when
[Multiple Outputs](/beam/receiver/output/multiple-outputs) have been added.

> **Info:** If the decoded input format is not supported by the target output (for example, UHD routed to a
> 3G-SDI-capable output port), the video must be down-converted to a supported format such as 1080p.

### Enabling Video Scaling

To enable video scaling for a specific _Receiver_ service, follow these steps:

1. On the **Home** page, select the **RECEIVER** item from the required feed, then click `Edit` to edit.

2. In the **Parameters** window, select the **Output** tab.

3. From the **Video scaling** drop-down menu, select the required output resolution. Select
   **No scaling** to disable conversion.

4. After completing the configuration, click **Save and Continue** to apply the changes.

> **Info:** If the decoded input format and the selected **Video scaling** is not supported, an alarm will be
> raised.
