Overview

Although Singular is designed for cloud-based workflows, it can work with HD-SDI for traditional broadcast. Singular works with all the major brands and operating systems and with our open environment, you can create your own custom solution.

Creating a Custom SDI Setup

There are four general steps you will need to take to create your own custom Singular SDI workflow.

Although we provide specific instructions for each step of the workflow, we encourage you to experiment and come up with a workflow that works best you. We cannot be comprehensive for all possible workflows so what is provided below is a few recommended options.

1 - Copy your Output URL

Within your control application, click the Share button and copy your Output URL.

2 - Add your overlays to your encoding software

Use that Output URL to add your overlays to your encoding software. Singular works with a variety of encoding software in two general categories: cloud and desktop. The following are links to tutorials on adding overlays to cloud and encoding software.

A. Adding Singular overlays into Cloud Encoding Software

B. Adding Singular overlays into Desktop Encoding Software

3 - Install & prepare an I/O device

Install an I/O device so that your encoder can output an SDI signal.

Here is a tutorial on getting an SDI Output Using Blackmagic Decklink.

4 - Get HD-SDI output from your encoder 

Once your overlays are added to your encoder and an I/O device has been prepared, you will be able to get an HD-SDI output.

Here are a few encoder specific tutorials on getting an SDI output after preparing a Blackmagic Decklink:

SDI Out - OBS 

You can now output to SDI using OBS. Follow the instructions below to connect OBS to your SDI output.

SDI Out - vMix

Vmix is one of the more popular pay-for streaming applications (encoder), and there are many reasons to pay for it! Check out all the goodies here on the Vmix website.

In this article, we are going to go over adding your Singular layer in an HD-SDI setup in which Vmix is generating a Key and Fill signal for you graphics layer.

NOTE: This installation is compatible with a Blackmagic, Decklink Quad 2 card. For card recommendations check out the vMix "Supported Hardware" page.

Installation

1 - Download vMix - Download vMix onto your computer which can be found here.

  • If you are new to vMix there are great resources for learning how to install and set up your application. For installation and getting started, try their resources page here for helpful tutorial videos.

Configuring Output Settings

2 - Configure Output Setting - This is done by clicking on the Setting icon next to External and selecting “External Output Setting

vmix_sdi_out_1.png*Note: It will launch this window that will default to the External tab. This will be your main program output where you will select which Channel on the Blackmagic Decklink Quad 2 card will be your output. 

3 - Select External Renderer - Check the box of “External Renderer

4 - Select Device - Select the device you want to use which in our case will be Decklink Quad and you will want SDI 1 so the selection will be “DeckLink Quad (1) 1

SDI Out - Caspar CG

Yes! It is possible to translate a web source to an HD SDI output. With this setup, you can get a traditional Key and Fill channel for your Singular.live web layer.

CasparCG is a free and open source software that supports real-time playout of mixed live and recorded audio/video input. It requires 2 software; the client and server to work build and process the graphics.

NOTES:

  • The Caspar CG Setup is only available for Windows and Linux users
  • You'll need a video card like a Blackmagic Decklink Quad 2, with a recommended configuration 

1 - Download the server and client software – For the server, go to http://builds.casparcg.com/
