i think there is something wrong in the conversion from camera to prores.
try to convert using Compressor if you can do this with it (i never worked Panasonic with) o try another codec. Make a test with one clip
I do a conforming 3 days ago from 30 to 25fps with cinema tools from a canon 5d files converted to prores with no problem.t
