Fix Zoom White Screen in OBS

My current OBS Studio Version: 27.2.3 (64 bit)

Using OBS to capture or record Zoom meeting may result in a white screen if you're running it on Windows with the default "Auto" setting for Video Rendering Method.  In this case, the default graphics API used in Zoom for rendering is not suitable for your camera.

Changing the rendering method to either "Direct3D11 Flip Mode" or "Direct3D" should fix the issue.
  • For HD video, choose "Direct3D11 Flip Mode"
  • Otherwise, choose "Direct3D11

Navigate to Zoom Video Advanced Settings and Pay Attention to Camera Settings

Firmware Update Failed on the 2nd Canon with Same SD

Recently I've done firmware update on my two old Canon EOS cameras using the same SD card, specifically, EOS 7D and EOS M3.  I did it to M3 first, then 7D.  But the update failed on 7D due to this error:  "Update file cannot be found.  Please check the memory card and reload the battery and try again."

File Not Found During Cannon Camera Firmware Update

There are two (2) ways to fix this.

  1. Reformat the SD card before copying the firmware file into it for firmware update if you don't mind losing all files.
  2. Simply remove or temporally save all  DCIM\CANONMSC\*.CTG file(s) in the SD card to someplace else before firmware update.

I did it with the second approach.  As soon as the camera detected the firmware file, the update went smoothly.
