You can use Vidpresso upstream of your switcher or production software if you have an existing live streaming workflow.
NOTE: If you don't have some of the options explained below, please contact your Facebook SPM or firstname.lastname@example.org to have the functionality added to your account.
Part One: Connecting Vidpresso Output to your Switcher/Software
To start, create a new stream.
On the stream setup tab, click on the drop-down menu under "Origin" and select "External."
If you are using Vidpresso with OBS, Wirecast, Livestream Studio, Grabyo, Xsplit, Vmix or any other software or switcher that supports browser overlays, copy the "Output URL" (below the "Origin" drop-down), and paste it into your software's or switcher's web source or browser source layer.
NOTE: Specifically for OBS, be sure to set your width and height relative to your other sources. i.e., 1920 x 1080. Vidpresso will render your graphics based on your aspect ratio settings in the Stream Setup tab of Vidpresso. The width and height settings for your "Browser" layer in OBS determine the aspect ratio that layer will be drawn as. If the ratios don't match, you'll see your graphics from Vidpresso... but they won't appear in the right place.)
If you are using Browser Overlays – Jump to Part Two
However, If you are using Vidpresso with a traditional switcher, or if your software doesn't support browser overlays, make sure that your switcher or software can do chroma-keying. Select a graphics package with a green screen background and click "Save."
Open the "Output URL" (below the "Origin" drop-down) in a new Chrome window or on another computer.
Make that Chrome window fullscreen and hide the toolbar. Chrome> View> Always Show Toolbar in Full Screen
Sending this Vidpresso output to your switcher or software depends on the type of switcher or software you are using. For most traditional switchers, you'll need to connect an HDMI cable from your computer to an input on your switcher. Then, you only need to key out the green background using your switcher's keyer.
If you're using another software solution, you might need to set up a screen capture or scan converter to bring in the Vidpresso output. Refer to your software's user manual for instructions regarding this.
Part Two: Receiving Data from your Facebook Live
Now that Vidpresso is showing up as a layer within your software or switcher, you need to paste the stream key from your Facebook Live post into Vidpresso under "Existing Facebook Post" and click "Save."
When you are ready to start your broadcast, click "Start" at the top of the screen. This allows Vidpresso to receive the data from your Facebook Live.
Important note: Clicking "Start" when using Vidpresso as an external source in this way will never actually start streaming. It only starts aggregating comments and polling data.
When you are done with your broadcast, make sure to click "Stop" at the top of your screen.
