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).

  5. Turn on the projector.

  6. Lower the projector screen.

  7. Log into the streaming computer.

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

  9. Integrated presenter setup:

    • Connect to the switcher.
    • 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.

  10. 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.

  11. 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 SQ6 ASIO device).

Bible Study Preparation

  1. In Integrated Presenter, open the Aux Output, Advanced PIP Control, and Advanced PIP Location views.

  2. We're experimenting with a new Bible study layout.

    • The background source defaults to the Integrated Presenter slide deck. Set the fill source to the lectern camera.
    • Set the PIP to 70% scale, align it center-left, and snap it into place.
    • Preset the lectern camera, turn on USK, and set liturgy to Tie.
    • In the Transition area, set background (BKGD) on, set PIP Fill Source to PROJ.

  3. Take the slides out of Drive mode - set to None. Advance to the Bible study title slide.

  4. Wait until pastor has logged into the tablet before using the "On Air" key to route the tablet's output to the projector.

  5. 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.

  6. 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. Don't worry about extra footage at the start of the recording; video recordings are trimmed in an editor before being uploaded or distributed.

  7. 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.

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

    • Unlock the Program row and hot swap the organ camera to the program output.
    • When the prelude is finished, use the Auto transition to put pastor (lectern camera) + layout + tablet output to program.
    • Remember to put the slides back into drive mode before Bible study finishes.

During Bible Study

  • Alternate between lectern + slides + layout and the center camera every few minutes at appropriate breaks in the content.

  • 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.

  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.

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, end the stream and stop streaming and recording after announcements and before communion begins.

After Service

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

  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. Collect the chat logs from Bible Study and Service.

    • Launch Ubuntu
    • Navigate to ./local/bin
    • 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.
    • Invoke ./chat_downloader <video_link> TODO: Add the file format arguments.

  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.
