Swap ideas for file types in FCP
 

Hi,
I have a FCP project with master clips in the .DV format. They were used in several sequences as sub-clips. I now know that I can't use the Smoothcam filter on .DV files and need to replace them with .MOV files. I've finished converting the new master clips but I'm wondering now if anyone knows of a clever way to replace all these .DV subclips in the sequences with .MOV subclips? So my project would be visually identical (just swapping the formats). Thanks for any tips
