# Configure the Live Encoder service The following sections explain the basic configuration for the Live Encoder component. For advanced configuration, see the following sections of Live Encoder: - [Input parameters](https://docs.mediakind.com/beam/live-encoder/configure/input) - [Encoding parameters](https://docs.mediakind.com/beam/live-encoder/configure/encoding) - [Output parameters](https://docs.mediakind.com/beam/live-encoder/configure/output/configure-output) To configure the Live Encoder, follow these steps: 1. Click next to the **Live Encoder** component within the feed. The Live Encoder settings open. 2. When you get to the **General** tab, the name is already pre-defined. It will be incremented at each new feed instance so you don’t need to change it. ## Configure the input [Section titled “Configure the input”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#configure-the-input) To configure the video, audio and data components, follow these steps: 1. Go to the **Input** tab. 2. In the **General parameters** section, select the input type: - [**SDI**](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#sdi-input) - or [**SMPTE ST 2110**](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#smpte-st-2110-input) ### SDI input [Section titled “SDI input”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#sdi-input) Before you start: ensure you already [set up the SDI card for HD or UHD operation](https://docs.mediakind.com/beam/system-admin/maintenance/setup-sdi-asi-card). To configure an SDI input, follow these steps: 1. From the **General parameters** section: - Set the input **Type** to **SDI**. - Select a Connector from the drop-down list. - You can keep the SDI card number, by default **1** or change it. 2. Go to the **Input streams selection** section: the input video is already configured but you can add an input audio: - Go to the **Audio ID** section. - Click **Add**. You can either keep the default parameters or modify them as needed. - Click **Ok** to validate. 3. Click **Save and continue** to save your changes. ### SMPTE ST 2110 input [Section titled “SMPTE ST 2110 input”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#smpte-st-2110-input) Before you start: ensure you already [set up the SMPTE ST 2110 input operation](https://docs.mediakind.com/beam/contribution/how-to/setup-smpte-2110-input). To configure an SMPTE ST 2110 input, follow these steps: 1. In the **Input** > **General parameters** section, set the input **Type** to **SMPTE ST 2110**. 2. Configure the input video stream: - In the **Input streams selection** section, go to the **Video ID** section. - Click then enter the **SDP file location**. - Click **Ok** to validate. 3. Add and configure the input audio stream: - In the **Input streams selection** section, go to the **Audio ID** section. - Click **Add** then enter the **SDP file location**. - Click **Ok** to validate. 4. Click **Save and continue** to save your changes. **See also** [Limitations and Considerations for ST2110 and PTP](https://docs.mediakind.com/beam/contribution/how-to/setup-smpte-2110-input#limitations-and-considerations-for-st2110-and-ptp) [Configure SDP files on MK.IO Beam](https://docs.mediakind.com/beam/contribution/how-to/setup-smpte-2110-input#configure-sdp-files-on-ce1) [Setup the PTP for ST 2110](https://docs.mediakind.com/beam/contribution/how-to/setup-smpte-2110-input#setup-the-ptp-for-st-2110) ## Configure video, audio and data components [Section titled “Configure video, audio and data components”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#configure-video-audio-and-data-components) ### Configure the video component [Section titled “Configure the video component”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#configure-the-video-component) To configure the video component go to the **Video encoding** section. 1. Click to check and configure the video parameters. 2. Select the appropriate parameters for the video encoding. 3. Click **Ok** to validate. ### Configure the audio component [Section titled “Configure the audio component”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#configure-the-audio-component) To configure the audio component go to the **Audio encoding** section. 1. Click **Add**. A new window is displayed. By default audio codec is set to **Pass-through** but you can change it. 2. Select the appropriate parameters for the audio encoding. 3. Click **Ok** to validate. ### Save [Section titled “Save”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#save) Click **Save and continue** to save your changes. ## Configure the output [Section titled “Configure the output”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#configure-the-output) 1. Go to the **Output** tab. A default output has already been created. 2. In the top right corner, click . 3. Scroll to the **Common MPEG-2 TS parameters** section. You may change some parameters, especially **Standard**, **PCR PID**, **Program number**, **Service name**, **Service provider**. 4. Scroll to the **Output streams** section, click then tick the audio stream. 5. You can change the PIDs if needed. 6. Click **Ok** to validate. 7. Click **Save and continue** to save your changes. ## Configure advanced parameters [Section titled “Configure advanced parameters”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#configure-advanced-parameters) ### CBR [Section titled “CBR”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#cbr) To ensure that the video is output as a CBR elementary stream, you need to add an advanced parameter: 1. Go to the **Advanced parameters** tab. 2. Click **Add** then set **Mpeg2ts.NullPacketStuffing** to **False**. 3. Click **Save and exit** to save and finalize your service configuration. 4. Select the **Home** menu from the left menu bar to go back to the Home page. ### SCTE-35 pass-through [Section titled “SCTE-35 pass-through”](https://docs.mediakind.com/beam/contribution/configure-feed-components/live-encoder/#scte-35-pass-through) If passing through SCTE35 messages with a default configuration, a high proportion of null splice messages will be output in comparison to splice messages which contain actual splices. This can be adjusted using the **capDmif.maxScte35Bitrate** advanced parameter. Setting this to a value of **7520** will reduce the number of null splice messages in the output.
