With all the talk lately about Canon releasing updates to enable their cameras to be used as webcams, I decided to venture on a science experiment. I have a Sony RX-100 IV, an absolutely amazing camera that is just sitting idle. So decided to try and figure out whats involved in getting it to work as a webcam, and I was able to get it to work on both Windows and Mac. Here is how I got it done:

Tools Needed

Windows

  • Micro USB Cable
  • OBS Studio found here
  • Sony Imaging Edge Desktop Suite found here
  • OBS Virtual Cam found here

Mac

  • Micro USB Cable
  • Camtwist Virtualcam software found here
  • Sony Imaging Edge Desktop Suite found here

Configuring The Camera

Before connecting the camera to your PC or MAC, go to settings and under Tools, make sure “USB Connection” is set to “PC Remote”. Also when you connect the camera to the computer, make sure you set the camera to “manual” mode for the RX100. I noticed that if its set to any other mode, Live View will not work. You can change the mode once you kick off Live View in manual mode.

Configuration on Windows

Before you get started, make sure you install Sony Imaging Edge Desktop and the Remote app within the suite.

Install OBS Studio.

Now install the OBS Virtual Webcam plugin. Once you’ve installed all three apps, connect your camera to your computer via USB (using a data cable) and launch the Remote app. Once you launch the app, you will see your camera in the list below. Double click your camera and it will launch live view. If you dont see the option, try a different cable.

Now launch OBS Studio. Under “sources”, click the “+” sign.

Choose “Window Capture”, choose “Create New” and give it a name. Click “OK”

On the next screen, choose the following and click “OK”

  • “[remote.exe]” for “window”, set
  • “Automatic” for “capture method”
  • “Match title, otherwise find window of same type” for “window match priority”

You should see the following screen


You should now adjust the borders by holding “Alt” and adjusting the borders with your mouse such that only the video is selected as shown below.

Now in OBS Studio, click on VirtualCam within the “Tools” menu. Make sure the “Start” button is greyed out and that “Autostart” is checked.

Configuration is complete at this stage. Keep in mind that you should not minimize the Remote app while the webcam is running. You should also not resize the window for the Remote app.

Now go into the collaboration tool of your choice and you should see an option to choose “OBS-Camera” as your webcam. Below is my configuration in GoToMeeting. This will also work on Zoom, Skype and Teams.

Configuration On Mac

Similar to Windows, install Sony Imaging Edge Desktop and install the “Remote” app.

Install “Camtwist” from the link above and launch the app. Double click Desktop+ as the source and configure the settings as shown in the screenshot below. Click select capture area and select the video portion from the remote app. Click on “Save setup” and give it a name.

Configuration is complete at this point. Camtwist will be available as a webcam in your collaboration tool. Here is Skype as an example.

Based on my testing, the functionality seems more stable on Windows. On my mac, the Remote app occassionally pegs the CPU and crashes. This could also be due to the fact that my mac is older hardware as compared to my Surface Book 2.

Hope this was helpful! Do post feedback based on your testing!
