 We are using [[https://obsproject.com/|OBS]] on an iMac to ingest video & audio and stream to Youtube. The video signals are input using [[https://www.blackmagicdesign.com/support/family/capture-and-playback|Blackmagic SDI->Thunderbolt input interfaces]]. OBS is configured with a few scenes that should cover the basics for any regular service. If you have unusual requirements, feel free to add new scenes to handle whatever the people up front want. We are using [[https://obsproject.com/|OBS]] on an iMac to ingest video & audio and stream to Youtube.

-We have a two [[https://ptzoptics.com/sdi/|PTZOptics video cameras]] in the sanctuary, mounted above the sanctuary double doors. They're named PTZ 0 and PTZ 1 in both OBS and [[https://www.pantiltzoom.cam/|PanTiltZoom]]. You can find the PanTiltZoom app on the A/V iPhone, which should be sitting near the iMac. +We have two [[https://ptzoptics.com/sdi/|PTZOptics video cameras]] in the sanctuary, mounted above the sanctuary double doors.

 Lyrics and presentation material are presented using [[https://proclaim.faithlife.com/|Proclaim]] on a dedicated Mac mini.

 ==== PanTiltZoom Camera Presets ==== ==== PanTiltZoom Camera Presets ====
  
-Using PanTiltZoom, you can create 9 presets per camera. There's no "wrong" way to organize them but here's a suggestion:+Using PanTiltZoom, you can create 9 presets per camera. When saving presets, you can use a descriptive name to identify them. Here are suggested framings:
  
-  * Use 1-3 for teacher position, centered worship leader, full shot of the cross +  * A couple framings of the preacher 
-  * Use 4-6 for whole band and individual band member lyrics shots. Remember to frame these with a good area for lyrics since you'll be including lyrics most of the time for these. +  * Full shot of the cross, to use during greeting time 
-  * Use 7-9 for any special shots for that particular service/more band members/whatever you need+  * Worship leader, whole band, and individual band member lyrics shots. You'll want one centered on the worship leader for welcome time and some lyrics shots for during songs. The lyrics from Proclaim are white, so lyrics shots need a space on the darker side for you to place the lyrics. 
 +  * Any special shots for that particular service/more band members/whatever you need
  
 Each camera has its own presets. To avoid confusion I suggest configuring both with the same shots so that you can recall whatever you need regardless of which camera is inactive. Each camera has its own presets.

 +==== Stream Audio ====
 +
 +We mix the live stream audio separately from the sanctuary, using mix 15 on the sound board. You can use [[https://pae-web.presonusmusic.com/downloads/products/pdf/UC_Surface_ReferenceManual_EN_04042019.pdf|UniversalControl]] on the iMac, A/V Kindle, or a tablet of your choice for control. The stream is mix 15 (labeled Stream in UniversalControl) -- make sure you select it, not the main (house) mix!
 +
 +The stream audio volume is critical. Folks online are listening on devices that have much less ability to deal with a wide dynamic range than we have live in the sanctuary. So, the audio volume needs to mostly stay as close to clipping as possible, without clipping.
 +
 +We have a compressor and limiter configured on the stream output to assist with this. When monitoring the stream audio, ignore how loud it sounds in your headphones. The audio meter in OBS is the only place you should look to determine whether it's the right level. Try to keep the audio between -1 and -10 dB, that is, mostly in the red meter area with some dip into yellow.
 +
 +If your headphones are too loud, adjust the headphone level (Mac OS system volume), not the stream output level.
