To preface, ATEM Mini's encoding functionality is a bit limited, which can sometimes result in inconsistent streaming to Subsplash Live; in these cases, pairing the device with OBS or another software encoder of choice can mitigate the issues. If you do want to use the built-in encoder of the ATEM Mini then follow along with the instructions below to quickly import a template for Subsplash Live! As a side note, we love the ATEM Mini as a way to connect cameras to OBS or other software encoders if you are using more than one camera!
The original "Blackmagic ATEM Mini" does not include encoding functionality and thus cannot stream directly to Subsplash Live; this article was written for the ATEM Mini Pro, and it also applies to the Mini Pro ISO, the Mini Extreme, and the Mini Extreme ISO.

Requirements
A text editor (a code editor like Visual Studio Code is strongly recommended)
Administrator-level access to your system files
An up-to-date installation of the ATEM Software Control (and the bundled ATEM Setup utility).
SRT Streaming
SRT Streaming
To use SRT streaming, both the ATEM Software Control and ATEM Mini's onboard firmware must be on at least the 9.6 version. The ATEM Software Control does not update the firmware of the ATEM Mini itself, and ATEM Setup must be used to apply the update. If you need help updating the firmware of the ATEM Mini, go through these steps!:
Download this XML file, which is custom-tailored to provide the ideal encoding settings for Subsplash Live (note that it will overwrite the profiles for any other streaming destination). Once downloaded, place the file on your desktop.
Open the file in a text editor.
On macOS: Hold [control] and click on the file, then select Open With and choose Visual Studio Code (if installed) or TextEdit from the list.
On Windows: Right-click on the file, then select Open With and choose Visual Studio Code (if installed) or Notepad from the list.
Navigate to the Media > Settings page of your dashboard and locate your SRT server URL. Part of that URL contains your unique stream ID, in the format
“…streamid=xxxxxxxxxx/xxxxxxxxxx/xxxxxxxxxx…”; starting after the equals sign and ending before the ampersand (&), copy the stream ID.Look through the document for where the line “<url>ENTER STREAM ID</url>” appears (once near the top). Replace the placeholder text with your Subsplash Live stream ID. Make sure to replace all of the text between the quotes, but don’t replace any part of the quotes themselves. The result will look like this:
When you are done, save and close the file.
Navigate to the folder containing the application files for the ATEM Software Control.
On macOS: Open Finder and press [shift] + [command] + [G], then paste this text into the text field to go directly to the folder: /Library/Application Support/Blackmagic Design/Switchers
On Windows 10: press [Windows] + [S] and paste this text into the text field to go directly to the folder: C:\Program Files (x86)\Blackmagic Design\Blackmagic ATEM Switchers\ATEM Software Control
Copy the new Streaming.xml file from your desktop and paste it into this folder. You’ll be warned that another file of the same name already exists; choose the replace option to replace the original file with our custom-made file. If you wish to save the original file rather than replace it, simply rename the original to StreamingBackup.xml before you paste the new one into the folder.
Restart or open your ATEM Software Control and you will now see "Subsplash Live RS" as your lone streaming destination option.
