hello. I'm an Avid editor but just got FCP at home for a doc project I've been working on. Most of the footage was shot 16x9 stretch mode on the DVX100a...but some of the footage from 3 years ago was shot in 4x3. In Avid there's a reformat tool for this. What's the best way to reformat the 4x3 footage to 16x9 in FCP?? Thanks.
