Camtasia (Windows): Green Line Shows in Video


On certain video files a green line can show on the side or bottom of the video.


This is a known issue that is fixed in Camtasia 2018.0.4 and later. Select Help > Check for Updates in Camtasia to install the latest version.

Camtasia 2018.0.3 and Earlier

This behavior will only occur when the hardware acceleration setting is set to software mode only. As a workaround:

  1. Click Edit > Preferences > Advanced tab
  2. Change the hardware acceleration setting to use graphics card

If you are using software mode only to improve performance while you edit we recommend editing your timeline using software mode only and then just before you produce, change your hardware acceleration setting to use graphics card to prevent the green line from showing up in the produced video.
