Whenever I do a night lapse, there is flicker in my video. I have the iso min and max set at 400, shutter speed at 30 seconds, and interval at auto. Please help me solve this issue. I have linked a YouTube video of the problem. It’s really hard to see since the quality gets downgraded on YouTube, but If you look at the top of the screen you can see, the lighting flickers from brighter to darker.
