If you captured 24p, without removing the 2:3 pulldown, then your sequence setting should be 29.97. If you have the removal (DV-NTSC Advaned 2:3:3:2 Pulldown Removal - thats ur capture setting) then i'm not really sure
Which mode did you shoot in, 24p or 24pa (advanced)?
If you shot 24p (normal) then, yes, you imported with the proper format (NTSC DV 48 kHz.)
If you shot in 24pa, you should have removed the pullldown, usually by selecting the "24p (23.98) Advanced Pulldown" capture preset, and then edited in a 24p timeline.
See this article for a crystal clear explanation of which capture/edit settings to use:
I have a similar question related to this thread - I shot 1/2 my tape in 24p advanced, the other in 24p (mid stream changed to conform to dual camera approach with another camera person). I was not sure how to capture the footage, since I'd like to use both segments of the tape. Should I change the capture settings for each segment but keep in the same project?
