Hi Shane,
The videos are indeed NTSC 29.97. I cut and pasted them into a new sequence and they are green and playable. The problem is that they are not 16×9 but 4×3. If I change anything in the sequence to possibly fix thgis it becomes un-rendered. How can I get this sequence back to filling a 16×9 screen again. THANKS SO MUCH FOR YOUR TIME ON THIS! By the way the DSLR footage scattered throughout is red in the render area, all other footage (most of it) is indeed green.
