The Gear

Recently I picked up the Sony a6400 as my new webcam, and despite watching several YouTube videos on how to hook it up to my computer, there was some missing information. First off, there was some gear I needed to pick up:

I also made to sure to pick up the plug-in battery so the camera doesn’t die while I’m recording. Here’s everything you’ll need in a nice convenient Kit:

The Chain

Once you have everything in place, the chain works like this.

  1. Add the plug-in battery and memory card
  2. Plug the micro HDMI side of the cable into the camera
  3. Plugin the HDMI side of the cable into the Cam Link
  4. The other side of the Cam Link is USB. If you can, plug this directly into the computer

On the camera, make sure the dial is set to movie recording mode. If you keep it on Auto, you will not be able to use 4K:

  1. Press the Menu button
  2. Go to the Setup Tab (it’s Yellow with a toolbox)
  3. Then to got Setup4
  4. Select HDMI Settings
  5. Make sure HDMI Info. Display is set to “Off”

Once this is set, you’re ready to start recording, which you can do right from Quicktime or OBS.

  3. hello, the sony a6400 allows for charing while shooting… why would you still need a dummy battery? Thanks

  5. I have set up an a6400 for streaming, with the CamLink and a dummy battery. It keeps turning off mid-stream! Is there a setting I need to check?
