Live streaming does not have a one size fits all solution. But, the steps we are providing in this article do provide a simple way to send lyrics from ProPresenter 7 to a program called OBS and overlay them on top of a video source.
You will need to download two separate things for OBS to work appropriately on your computer. You would go to https://obsproject.com/ and click on your OS to download the software. Then, head to https://github.com/Palakis/obs-ndi/releases/tag/4.7.1 and under the Assets section download the "macOS.pkg" file for macOS or the "Windows-Installer.exe" file for Windows. Once you have downloaded and installed both of these things, you can continue to the next steps.
The ProPresenter Set-Up
The first thing you want to set up is the output that ProPresenter is going to send into OBS. So in ProPresenter, open your screen configuration window from the Screens Menu and add a new NDI Screen, in this example, we have named it “Stream Lyrics”. Then, click on the Alpha Key tab and check the box for Enable.
Once you have done that, you will open the Edit Looks window from the Screens Menu and on the “Stream Lyrics” screen, we are going to select the slide option and apply an alternate, lower third theme that you have created in your theme editor.
The OBS Set-Up
When you open OBS, the first thing you want to do is to click the + icon under sources to add your source(s). For our purposes, let’s first select NDI Source. Once you click that, the window will look like this:
In this window, click on the Source Name and locate your ProPresenter 7 connection (likely your computer name) and click Ok. Then the main window will pop back up and you will see your ProPresenter output showing on the main window! (if it is the wrong size, no worries, we will fix that in a few steps).
Now, click the + again and select your video input source. This could be a Blackmagic Device, Video Capture Device, etc. Unfortunately, this is the step we can help with the least as it will be different based on what your device is. When adding this, make sure the appropriate mode is selected (like 1080p60, etc) and click Ok.
Once you have done both of these steps, you should see both sources showing in the sources window of the main window of OBS. The one that is the top of the list is the one that will show “on top” which is why you aren’t seeing both at this time in the output window. For our purposes, “NDI Source” should be at the top. If that is on the top, it should appear correctly in your window!
If you are seeing everything sized incorrectly, go to the OBS menu option and click Preferences. Then click on the video tab and set the Base (Canvas Size) resolution to whatever your ProPresenter Output is.
