Camtasia (Windows): Produced video has sections that are black or green


Produced video has sections that are black or green.


We now have a patch available that lets Camtasia Studio 7.1.1 use more memory that is available on a PC running Windows Vista or Windows 7. This article does not apply to computers running Windows XP.

On a 64-bit machine we can go from Camtasia using 2GB to 4GB of RAM. On a 32-bit machine we can go from using 2GB to 3GB of RAM.

To install, follow these steps:

  1. Open Camtasia Studio 7 and click Help->About Camtasia Studio. If you have version 7.0, 7.0.1, or 7.1.0, you will need to update to Camtasia Studio version 7.1.1. Download the updater from the following link or use the built-in update feature from the Help menu.  If you already have version 7.1.1, proceed to step 2.
  2. Exit out of Camtasia Studio so it is not running.
  3. Download "" which is attached below. Save the file to your hard drive. When the download is complete, right-click the .zip file and Extract the contents.
  4. Open the following folder:
    64-bit machine:
    C:\Program Files (x86)\TechSmith\Camtasia Studio 7
    32-bit machine:
    C:\Program Files\TechSmith\Camtasia Studio 7
  5. Drag or paste the extracted file from step 3 into the folder opened in step 4. There is already a file with that name, so Windows will prompt to replace the older file. You MUST move the file into that folder; trying to run it from any other location will result in an error message and Camtasia Studio will not launch.

Below is a video of the steps:
