After I have recorded and start to play back the video of my screen shots, the screen blinks off and on at the start of the video. Also when I group to recordings together, it blinks off and on at the transition. I thought this would go away once I created the MP4 in production, but it still blinks off and on at the start and when playing through the two grouped recordings. Has anyone else experienced this? Is there anything I can do to correct this?
