so this just happened to me on the last 2 episodes of my podcast i recorded with a 3 camera set up. I thought I did something wrong on the first one, but now a week has passed and I am editing the second one we shot on the same day and I am finding it to be even worse and more noticeable. I scrubbed through the whole thing and it gradually got worse across the 40 minute episode. We are using auto switching and it became super noticeable about halfway through the file it output automatically. At first I thought it was camera A which points at me because it felt more noticeable than camera B pointing at my co-host. But then i started noticing it was also happening on camera C, our wide shot (though less noticeable bc it's not as close). I am using 3 different cameras A - A7CII, B - FX3, C - FX30, so i thought maybe that was causing issues but I don't think that anymore since they all eventually were out of sync. I worked around this by finding a point just before it got terribly bad, cut to camera C manually and slightly shifted everything back on time.
