A7iv flickering in Video outdoors

[Paul harris]

I was shooting my camera outside and I was getting flickering. So this certainly had nothing to do with fluorescent lights because it was only sunlight. I believe my camera was in auto mode, but this has happened several times now. It needed to be in auto because I was running more than one camera, I'm not the greatest with camera settings, and the sun was coming in and out of the clouds. I know putting it in manual would solve this, but assuming that at my skill level I need to use auto outdoors, can anybody tell me what the problem is, is it iso? Do I need to set my iOS and put it in mode P? I am in the latest firmware, 3.02. Maybe there's a setting where it can gently adjust from one iso setting to the next? Any thoughts or help would be greatly appreciated. Thank you. I'll include a link to a video so you can see what I'm talking about.
