you may want to change your sequence setting (using Apple Pro Res 422 or DVC50).
I’m not sure if you can import with the DVCpro50 or Apple Pro Res, (if not just stick with the NTSC/DV) and just change the sequence setting.
Whats is the end use of the video? Will it be for TV/DVD? Or web only?
If web/computer only, use the De interlace filter (VIDEO filters).
If it is for TV broadcast, its supposed to be interlaced. Can you setup TV to view the project while working on it….
IF it is for a DVD, I’m bot sure about interlaced…
