I have run into an intermittent problem importing Panasonic AVCHD files (MTS extension) into PP CS6. Occasionally, when I preview an imported file, it appears reversed (negative image) and upside down in the preview monitor. Any clips I preview after that appear the same way. I can clear the problem by exiting and relaunching PP. BTW, I am copying to my hard drive the entire contents on the card on which I am recording, with no alteration to the file structure.
Has anyone else run into this sort of problem? Any help troubleshooting and fixing greatly appreciated.
