Welcome to the forum.
Can you provide the full specs. of those particular, problem Clips, and also your Sequence setting?
Thanks for getting back to me. I have discovered that the footage has 2 different frame rates. The clips are 23.976 and 29.976, 1920x1080. The sequence is 1920x1080 @ 23.976fps. I know they should ideally be conformed and I will do that, but this is the first time I've had this issue using Premiere. What I have done is unlink and relink the footage and still the same thing. It does not crash if I do not mix the frame rate in my selection of clips.
i am getting that same error when i try to Nest all five cameras, they are mixed frame rates dut to 3 dif cameras used but i editng the first show and nested without any trouble now onto the second show and its giving me this error.
