Hi Clare.
Case 00379485 has been created should you need to contact us directly regarding this issue.
Please could you advise if you are trying to record full screen or just an area?
Have you loaded up a flipchart and then tried to do a screen recording? Does this happen if you are using a blank flipchart?
Please could you attach a screenshot of the error message?
Under File>Settings>Recordings, Is the tickbox checked or unchecked for "Disable hardware acceleration during recording"? And what is the capture frame rate set to?
I look forward to your response.
