Could you share an example of what these lines look like and how they move?
From your description, no, it's not moiré.
If these are lighter colored horizontal lines slowly rolling through the frame they are caused by the switching unit that converts AC power to the DC power required to run LED fixtures beating against the frame rate of your camera. This is extremely common in theatrical LED lighting that isn't "high-end" and optimized for shooting video. I'm afraid your shots are ruined. It would take hours of handwork and fiddling to try and repair the shots. You should have noticed it when you were shooting but sometimes it is hard to see.
Professional LED fixtures have very high frequency power supplies to avoid this problem.
Thank you guys so much. I'll try and post a sample later. Rick, it may be something where the hours of handwork will be worth it so I may need some direction on that. I know I should have noticed it but that's how we learn and grow, right? Poco a poco...
