If the aerial image on your environment looks fine in the Environment and Event Editors, and it looks fine in the Traj Sim and Video Creator windows in the Playback Editor, but appears scrambled in the final recorded video, the issue is due to a behavior of the Windows video recording subsystem on your computer.  The cause of your issue is that the location of your aerial image is not on your local drive, but actually on a drive across your network such as your server.  If you place the image on your local drive and reapply it to your environment, it will appear as expected in all of the Editors and also in your final recorded video.
