After you uncheck the anamorphic box for the sequence, you’ll need to manually resize the clips to work right. It’s really not that hard though, because by using the paste attributes feature, you just need to change of the 16×9 clips, then paste the attributes to the rest of the clips by selecting all of them at once. Same with the 4×3.
I’m not sure I explained that very well, so you might want to look up how to use the paste attributes feature. Also, be sure to change the distort property along with the other properties to get your footage to look right in a 4×3 timeline.
