Overview

This guide is intended to show you step-by-step how to set up an MBR stream using HTTP Push. For more information on the V2 UI in general, see this guide.

Step-by-step

Setting up an MBR stream consists of the following parts:

1. Configure AV Input
2. Create and configure MBR Group
3. Create and configure Video Profiles
4. Create and configure Audio Profile
5. Configure HTTP Push

Each part has its own steps, so we will be going through each part as its own section.

Configure AV Input

Important: Ensure encoding is de-activated before making changes to MBR group. Once changes have been made, encoding may resume.

AV Input is where the input resolution will be reported as well as where the selection of HDMI or SDI and embedded audio or 3.5mm audio can be chosen:

1. Make sure the reported input resolution/framerate matches the expected source resolution/framerate
2. Make sure the Video Input selected matches the input source being used
3. Make sure the Audio Input matches the source audio
4. Click Save

Create and configure MBR Group

MBR Group is where all of the common settings for the Video Profiles will be managed.

1. Click + Add MBR Group
2. Click Group Settings (should replace + Add MBR Group)
3. Set the respective settings to the desired configuration
   
   • The defaults here are good for a majority of use cases
   • If trying to get the absolute lowest latency possible, set Quality/Latency to Lowest
4. Click Save

Create and configure Video Profiles

Create as many Video Profiles as are needed for the stream. The combined resolutions/framerates must not exceed 4K30. To demonstrate a common ladder (set of different resolutions), we will be using the following:

• 1x 1080p60
• 1x 720p60
• 1x 480p60
• 1x 360p60

To set up this ladder:

1. Click + Add Video Profile for the number of Video Profiles in the ladder (in this case 4 times)
2. For each Video Profile, click the name in the left sidebar then,
   
   1. Click the name in the main configuration menu (should have a pencil icon next to it) and type the new name of the Video Profile
   2. Set Video Scaling to the desired resolution for the profile
   3. Configure the rest of the settings according to the desired ladder
   4. Make sure to turn MBR Group Member to ON
   5. Click Save

Create and configure Audio Profile

1. Click + Add Audio Profile
2. Click the new Audio Profile name that appears
3. Click the name in the main configuration menu (should have a pencil icon next to it) and type the new name of the Audio Profile
4. Configure the desired settings
5. Click Save

Configure HTTP Push

HTTP Push is where the output settings for the MBR stream will be set. For detailed information on HTTP Push, follow this guide. This section will talk about the MBR specifics of HTTP Push setup. Enabling MBR for HTTP Push is very easy:

1. Select the MBR Group as the Video Source
2. Select the previously created Audio Profile and the Audio Source
3. Configure the rest of HTTP Push according to the guide linked above
