I obviously have an HVX200 and here's want i'm trying to accomplish

My final output, I would like to be a 24p DVD, I want the DVD to be the same video rate as what any movie you would buy in the store to be.

I obviously want the look of 24fps and I want to shoot and edit in 24fps (23.98)

But I would rather shoot in 1080 than 720, I am using FCP 5.1 (the upgrade) and im not sure if it installed correctly or something, because I do not see DVCPRO HD 1080 24p. I want to edit 1080 in a 24 timeline

I dont know the difference between 1080i 24pa and 720p 24pn
 
I know nothing about FCP, so I won't get into that, but why would you want to use 1080i instead of 720p if you are creating a DVD, which is by definition SD? 720P makes much more sense because some of the really cool HVX features only work in 720P and it's easier to edit.
 
I haven't physically done this before, but my guess is that you would start with a 1080/60i sequence and then go into settings and change the editing timebase to 23.98. Then remove the advanced pulldown from all your clips using the the tools menu. That should give you 1080/24p.

However, my suggestion would be to just shoot 720/24pn. Why? One, you don't have to go through all of that pulldown removing nonsense. Two, you are going to save space on your P2 cards and be able to shoot more at one time. Three, you'll be able to play with the HVX's wonderful over/undercranking feature much more easily when recording in 24pn. Lastly, your final output is DVD which is inherently SD so the difference between 1080 and 720 is going to be marginal at best. If you were going to broadcast HD or a film print that would be different, you might want that extra rez, but for DVD I really think trying to shoot 1080 will just be more of a problem then its worth.

Good luck.
 
I use Avid and let me say that 720pN makes life SO much easier. Just haveing 24 pure frames is a world of difference.

In 720p when shooting 24p there is actually 60 frames recorded to the P2 card, some are duplicated. Later in post those frames are discarded and only the 24 "flagged frames are imported. In 720p 24PN or "Native", only the 24 frames are recorded so therefore it is easier to deal with later in post and it also doesn't take up as much space on the cards as there is no duplicate frames.
 
There is an update to FCP 5.1 that brings it up to 5.1.2 and ads the 1080 24p Easy Setup as well as some cool new P2 Import functionality.

Check out this previous thread: http://www.dvxuser.com/V6/showthread.php?t=72630
Go to the second page of the thread to see the screen shot of the 1080 24p setup.

Just go to your "Software Update" under the Apple menu to do this instead of downloading from the link in the thread.

I shoot in 1080 a lot. It is worth it to me to have the maximum resolution in the original footage. You never know when you might need it for other purposes.

Best.
 
I've done tests and so has Barry. 720p and 1080p look VIRTUALLY INDENTICAL when downrezed to an SD DVD. Remember, they all come from a 1920x1080 signal anyway. 720pN is going to give you easier editing, a completely progressive environment with no stupid frame extraction stuff or fields, variable frame rates, and 2.5 times the memory card space. Honestly, the only reason to other with 1080p is if you're shooting for a broadcaster who requires it as a format or your planning a film out and even then the resolution difference is only 10-20%.
