you talking about mov renamed mpg ? thats the only time I saw any 'conforming' at all with the dslr stuff... never saw conforming as mov. DID see conforming as mov renamed mpg. Plus only got sound... which is another issue...
Its reconforming the Project that has absolutely nothing in the Sequence yet although the project bins are a mix of .mts and .mov source files. (referencing approx 50GBs worth)
So Why does Premiere do this?
It happens sometimes. I haven't yet seen a definitive cause put forth.
I agree ...and it would be nice for the Adobe guys to come in and offer thoughts.
