How to Record Zoom Meeting with OBS on a Macbook Air

-

In this post, I document my Zoom Meeting setup with OBS recording.  


What is the Zoom Meeting about?

  • A 1-hour workshop on smartphone videography and mobile video editing. 
  • The Zoom session is not hosted by me, but by the organizer who invited me. 
  • I want to present my training slides and show my mobile phone screen.  
Here is the list of equipment used.
  • MacBook Air M1 - The Macbook Air M1 will be the main streaming device. 
  • iPhone 12 Pro Max - The iPhone will act as the camera to show my hands-on demo. 
  • Samsung Galaxy S10 Android Phone - The S10 is the mobile phone camera used for the demo. 
  • Skywater MultifunctionUSB Hub - This hub connects one USB-C from the Macbook Air to the Ethernet cable, the External SSD, and Power.  
  • Samsung T3 SSD - This SSD will record the session externally, so as not to slow down the internal drive. 
Here is the setup. 

Macbook...
  • Connect the USB Hub to a USB-C port on the Macbook Air M1.  
  • Connect the Ethernet cable direct internet to the USB Hub.  
  • Connect the External SSD to the USB Hub via a USB cable.

    PS: Without a headset, I can record participants voices from Zoom. That means I cannot go far from the laptop.

Check it out! https://youtu.be/d-wALSd3nn8 I didn't expect the rubber plugs. It was a nice surprise. The case fits snuggly, with access to all the ports. The keyboard cover is almost invisible to the eye. I have no intention to use the screen protector. Why? I need to see the true color of the display for my YouTube videos. ~ Adrian Lee  @Adrian Video Image  The video was recorded on iPhone 12 Pro Max with Filmic Pro app in 4K 60fps and edited with Capcut.
