Hey, I’m having the same problem, I shot panasonic 24p. I’ve looked over my capture settings, sequence settings, and preview settings and they all match up. The strange thing though is that the problem suddenly started, and I haven’t changed any settings. This leads me to believe that it has to do something with the clips. My capture settings haven’t changed, and I’ve looked over the original video and it’s definitely 16:9. I’m about to try recapturing on the hope it was just a fluke, but I’m totally boggled, any thoughts?
