+=== Video-Mixing Workflow
+ *  Before talk:
+    * Select correct source [1] in "Lecture Player" scene
+    * Connect to correct Jitsi-room [2], locally and on mixer machine
+    * Share OBS window on mixer machine
+    * Test with session host and speaker
+    * Activate "Everyone follows me" in Jitsi settings on local machine (More Actions -> Settgins -> More -> Everyone follows me)
+    * Make sure the speaking person is displayed or switch manually between speaker and session host, avoid tile view
+    * Start Jitsi live stream (sotm1-talk, sotm2-talk)
+ * Talk start:
+    * Notify session host and speaker you're about to cut to the Jitsi room
+    * Ensure Recording is enabled
+    * Activate "Jitsi via RTMP" scene for intro
+    * Activate "Lecture Player" scene after intro
+    * Watch audio level, adjust if necessary – target is -12dB (sometimes yellow, but never red)
+ * Talk end:
+    * Notify session host and speaker you're about to cut to the Jitsi room
+    * Activate "Jitsi via RTMP" scene for Q&A
+    * Activate "Loop Player" scene after Q&A
+    * Stop Jitsi live stream in current room
+For lightning talks, you have to select the next talk while the current one is running and cut to the "Lecture Player" scene again once the previous talk has finished.
+ * We could also add all lightingtalks to the player, if there is no moderation inbetween...

+=== Routing Video and Audio of the lecture player into Jitsi
+ * Precondition: There has to be an open NX session
+ * right click the lecture player scene to and select "Open windowed projector (Scene)"
+ * in Chromium: in the Jitsi: share this projector window and enable the microphone
+ * in the system "Volume Control" window switch to the recording tab
+    * Switch the "Chromium input" to the "Monitor of Null Output"
+ * Inside OBS Sessings (Audio -> Advanced) the Monitoring Device is also set to "Monitor of Null Output", thereby all audio sources with enabled monitoring should go to jitsi.
+    * check with your lokal Jitsi window, if audio works e.g. by enabling monitoring for the loop
+    * (gear icon below the audio level shifter -> Advanced Audio Properties -> Audio Monitoring to "Monitor and Output")
