It is not the best answer. As you have learned, you can’t mix footage from thwo different systems in the same FCP timeline. You need to choose the system in which you’re going to edit: NTSC or PAL. You then have to convert the non-standard footage to that system BEFORE you edit. Nattress does a good job of that.
Doing skipping the standards conversion step before you edit will make your life a LOT harder as you come to the end of the project. It might even force you start over from square 1.
