On Arrival and Before Bible Study

  1. Next to the pastors' room: Ensure the Universal Sequence Controller is on. If not already on, turn on the sequenced power.

  2. Ensure the chancel step spot lights are on. The light switch is on the wall near the door leading to the pulpit.

  3. Plug in the pulpit and lectern cameras.

  4. On the balcony, plug in the organ camera. Turn on the spot light for the organ, set the switch to 2 (II). If using PIP hymns, ensure the back camera is on: the power button is on the camera's front, below and to the left of the lens, it is also recessed slightly:

  1. Turn on the projector.

  2. Lower the projector screen.

  3. Log into the streaming computer.

  4. Open Chrome and use the shortcut to go to YouTube Studio. Open OBS. Open Integrated Presenter.

  5. Integrated presenter setup:

    • Connect to the switcher.
    • If using PIP Hymns and PIP Creeds, enable Condition 2 which is disabled by default:

    • Notes about using PIP Hymns:
      • The Setup PIP step will change the scaling, masking and position of the PIP - so if you have set up something for an anthem, this will overwrite your settings. To avoid this, temporarily disable condition 2 to not run the PIP hymn right before an anthem.
      • PIP hymns will never set/change the PIP fill source, so before the start of the service you must manually select the PIP fill. Typically, this will be BACK though sometimes the organ camera is appropriate.
    • Open the slide presentation for the upcoming event. Bible study may have its own slides, or its slides may be at the beginning of the worship service slides.
    • Drag the key and slides windows to their corresponding tiles on the multiviewer. Use the 'f' key to full-size them within their tiles.

  6. After OBS and Integrated Presenter are running, check to make sure the video image from the program output displays in the OBS window. Move a camera or perform a transition to ensure OBS is processing video and not stuck on the last received frame. If there are any problems, or if an error dialog displays when starting OBS, the streaming computer will probably need to be re-booted to resolve the issue. Do this check well before the livestream is supposed to start.

  7. Have the sound operator send some sound to the livestream mix to make sure audio input from the sound system is making it to OBS. Check that the audio input in OBS has a 12.0 dB boost (this is visible above the VU meter for the DANTE 1/2 device).

Bible Study Preparation

  1. In Integrated Presenter, open the Aux Output and Advanced PIP Control views. Once pastor has logged into the tablet, in the Aux Output column, route PROJ to the projector to put Pastor's tablet output on the projector screen.

  2. The new Bible class slide template includes the layout with PowerPoint on the left, Pastor on the right and the class title in the lower third. Integrated presenter includes a PIP location preset called BCLASS that matches this. This will be invoked a few steps later.

  3. In YouTube Studio > Content > Live Upcoming Event, locate the upcoming live event for Bible Study. Click the "View Live in Control Room" icon which looks like this: ((o))

    N.B.: Use all the default settings in YouTube Studio. The stream key, etc., are already set to match OBS' output.

    N.B: Do NOT click "Go Live" yet. We have only one chance to start and end the event. Therefore, go live only after completing setup. Also, don't end an event until it has completed. Once ended, an event cannot be restarted.

  4. Start streaming and recording 10 minutes before the Bible study start time. Make sure the video display is showing in the YouTube Studio preview (about 30 seconds after clicking "start streaming" in OBS). If no sound is being sent to the livestream mix prior to the prelude (normally the case), then YouTube Studio may display a warning about the audio bitrate being too low - this is OK - it will go away on its own a minute or so after audio is un-muted. Don't worry about extra footage at the start of the recording; video recordings are trimmed in an editor before being uploaded or distributed.

  5. Go Live in YouTube Studio.

    • The sound operator will have muted the house sound at this point, so from 10 minutes before to 5 minutes before, the stream will show the title slide and silence. Note: during the silent period, OBS may reduce the audio bitrate which may cause YouTube Studio to pop up a suggestion to increase the audio bitrate. No action is needed; this will go away when the prelude starts and the house sound is turned up.
    • Once streaming the title slide + silence, switch the green light on. This indicates to Pastor that the stream is up.

  6. About 5 minutes before Bible Study begins, the organist/pianist will start playing a prelude. At this point:

    • Advance to the organ prelude slide. The soundboard operator will un-mute the sound.
    • Turn the red light on which indicates that live audio + video are being streamed.

  7. When the prelude finishes, click the BCLASS option in the PIP controls area, then use the Auto transition to take. This will put the tablet + pastor + layout on air.

During Bible Study

  • If you need to remove the signal going to the Aux output (which feeds the projector), hold 'z' (set aux output source) and press 'b'.

  • Keep an eye on OBS - the bitrate should hover around 10000 Kb/s for our HD1080p stream settings. Also watch the chat feed in YouTube Studio -- look for reports about stream issues, especially if they originate from multiple viewers around the same time.

Between Bible Study and Service

  1. When Bible Study concludes, end the event in YouTube Studio. In OBS Studio, Stop Streaming and Stop Recording.

    • Turn off the red and green lights.

  2. Raise the projector screen and turn off the projector -- unless the projector will be used during service.

  3. Reconfigure Integrated Presenter: Turn off the Aux Output and Advanced PIP Location views.

  4. In YouTube Studio > Content > Live Upcoming Event, locate the upcoming live event for Worship Service. Click the "View Live in Control Room" icon which looks like this: ((o))

  5. 10 minutes before service, start streaming and start recording in OBS. Put the title slide on. When YouTube Studio indicates the stream is present, Go Live.

    • Turn on the green light, indicating to Pastor that the stream is up and sending the title slide + silence.

  6. Approximately 5 minutes before service, the organist/pianist will start playing a prelude. Switch to the organ/piano camera and the sound operator will bring the sound up.

    • Turn on the red light indicating that live video + audio are streaming.

During Service

  • The slideshow will preset and take most of the camera shots needed. During longer sections of the service, e.g. sermon and prayers, keep any eye on the time on shot counter. Dissolve / cut between cameras as appropriate (coordinate these transitions to coincide with breaks in pastor's speech).

  • Keep an eye on OBS - the bitrate should hover around 10000 Kb/s for our HD1080p stream settings. Also watch the chat feed in YouTube Studio -- look for reports about stream issues, especially if they originate from multiple viewers around the same time.

  • If the service includes communion, we will end the live event after announcements and before communion begins, unless otherwise instructed by Pastor:

    • Set the Slide Control mode to Skip and advance to the last slide linking to the Holy Cross service video series. Take this slide to put it on air.
    • End the live event in YouTube studio.
    • Rewind in the slide deck to the previous point (this will be near the start of distribution), then use the slide control Take button.
    • Put slide control mode back to Drive, then continue through the remaining portion of the service normally. This is so attendees in the parlour can see the rest of the service.

After Service

  1. End the live event in YouTube Studio. In OBS, stop streaming and stop recording.

    • Turn off the red and green lights.

  2. The video recordings for Bible Study and Worship are located in the Videos folder. Copy the video files to OneDrive\Holy Cross Lutheran Church\Livestream Recordings

  3. Rip the audio tracks from the Bible study and worship video recordings. FFMPEG is added to %PATH% so the command can be invoked from any directory:

    ffmpeg -i <input_file> <outputfile.wav>

  4. Copy the audio files to OneDrive\Holy Cross Lutheran Church\Livestream-Audio-Recordings

  5. Process the chat logs from Bible Study and Service.

    • Launch Ubuntu
    • Navigate to /home/avuser/chat
    • Go to YouTube, to the Holy Cross channel. Get the links to the Bible Study and Service. Note: it takes perhaps 5 minutes after a stream is completed before the chat is prepared.
    • For each link, invoke ./script.bash <video_link>

  6. Close Integrated Presenter, OBS, and Chrome, and lock the streaming computer.

  7. Initiate sequenced power down of the A/V equipment using the switch in the balcony.

  8. Unplug the organ camera and turn off the spot light.

  9. Unplug the pulpit and lectern cameras.

Streaming Computer Maintenance

  • If the C: drive is close to full, move older video files from the Videos folder to D:\Archive.
