Under the Sources section, click + and select Window Capture. This will bring up the window capture pane.
Make sure Create new is selected and keep Make source visible checked.
Once the source is added, double click the source in the Sources section to bring up the properties pane. In the properties pane, select Flipside in the Window dropdown menu and make sure Capture Cursor is unchecked.
Add your audio source to OBS Studio
Ensure you have added audio sources for both Mix/Aux and Desktop Audio. Mix/Aux captures your voice in Flipside and Desktop Audio captures the rest of the sounds in Flipside.
Adjust the sync offset to 80ms
Under the Edit menu, select Advanced Audio Properties and enter 80 into the Sync Offset (ms) field for the Mix/Aux audio source. Note: You may need to fine-tune the number entered here to find the ideal value for your setup. Values can range from 20-160.
Set the window capture area
In OBS Studio, you will see all of the Flipside interface in the window capture area. Move/resize this view to only capture the show and not the Live edit elements.
Connect Flipside and OBS Studio
In the Flipside camera switcher interface on the desktop, click Connect to establish a connection between Flipside and OBS Studio. You should see the connection status change to say it has connected.
Check your Windows audio settings
If you don’t see the audio volume changing in the OBS mixer area, you may need to make sure that Windows has the correct audio input source enabled. To see or change this setting, click on the audio icon in the lower right corner of the Windows desktop. Click on the audio input source name to select a different input source.
Check OBS audio settings
If you still don’t see the audio volume changing in the OBS mixer area, click on the gear icon next to the audio source in the OBS mixer area and select Properties. Try choosing the appropriate audio device in the Device selector.
