Video recording (no live streaming)

[edit | edit source]

Recording a presentation requires less equipment than streaming a presentation, but can require a bit of post production work, especially if a slide deck is present.

Necessary equipment

[edit | edit source]
  • Video camera with an audio input
  • Camera tripod
  • Output from the room audio mixer to the camera (an auxiliary bus of all the mics in the room)
  • Headphones to monitor the audio
  • HDMI cable, video adapters, XLR cable, XLR cable adapters
  • Gaffers tape
  • The slide deck (if there is one) so that it can be edited in to the recording in post production

Required know-how

[edit | edit source]
  • Ability to use a tripod to pan/tilt/zoom a camera
  • Setting and striking AV equipment rigs
  • Having a basic grasp of the equipment and what each hardware piece does so that basic troubleshooting can occur if problems arise

Video recording (with live streaming)

[edit | edit source]

The following equipment and know-how is needed to produce a live stream with decent production value:

Required equipment

[edit | edit source]
  • A laptop powerful enough to stream a video with a bitrate of at least 2500 kbps (720p minimum bitrate) running OBS (Open Broadcast Software)
  • Video camera with an HDMI output and an audio input
  • Camera tripod
  • USB video capture card (inputs HDMI video from camera and delivers it to the streaming laptop via USB)
  • Hardwired internet connection that is at least 10mbps upload/download
  • USB audio interface (inputs audio from mixer and delivers it to the streaming laptop via USB)
  • Output from the room audio mixer to the USB audio interface (an auxiliary bus of all the mics in the room)
  • Headphones to monitor the audio
  • Gaffers tape
  • HDMI cable, video adapters, ethernet adapters, XLR cable, XLR cable adapters
  • If a slide deck is part of the presentation
    • First option:
      • We need the slide deck before the presentation
      • A second laptop to host the slide deck
      • A second USB video capture card to send the slide deck to the streaming laptop
      • The person operating the stream needs to advance the slide deck along with the presenter
    • Or the second option (preferable, if possible):
      • A second USB video capture card to send the slide deck to the streaming laptop
      • A 1 to 2 HDMI splitter in between the projector and the laptop hosting the slide deck
      • An HDMI cable to run from the second output of the splitter to the USB video capture card

Required know how

[edit | edit source]
  • Ability to use a tripod to pan/tilt/zoom a camera
  • Setting and striking AV equipment rigs (knowing how to properly wrap cable is a huge plus)
  • Having a basic grasp of the equipment and what each hardware piece does so that basic troubleshooting can occur if problems arise
