  2. Select Device:
    1. Click on the Devices menu and choose your camera.
    2. Under the Options menu, select Preview.  You should now see your video.
  3. Start Capture:
    1. Go to the Capture menu and select Start Capture.
    2. During the video capture, please observe the video panel to see if it freezes up.
  4. Saving the Capture file:

  • Please use amcap.exe to see if you can duplicate the video freezing that you experienced in the Webex session.
  • During the video capture, please observe the Amcap video window to see if your video freezes.
  • Please make sure that this is tested on the computers that experienced the video freezing in Webex sessions.
  • Since this issue in the Webex sessions is intermittent, it would be best to test this more than once on the computer experiencing the problem.  We are trying to determine if the video freezing also occurs while using other video capturing software.
