DVX100 and FCP settings

The following discussess shooting 24 fps with the DVX100 (and 100A) for film looking frame rate. For standard video go with Scene File F1 default which is 60i (60 interlaced fields)

For tape:
Shoot 24p (Scene File F5 default) Direct import to 29.97 sequence. No need to remove pulldown. Edit as you'd like. However you won't be able to easily convert back into 24fps after the edit since edits may cross fields (if you cut at a point where part of the frame is on the included frame as a field and the other part is on the next frame that's not included you'll have trouble).

For DVD:
You can do the same as above for 24 fps footage in 29.97 or you can shoot 24pa (Scene File F6 default), advance pulldown removal into 23.98 sequence and go out as 24fps DVD.

For Film:
You can shoot 24pa, advance pulldown removal into 23.98 sequence and go out to film. Note that you can shoot 24p and do the same thing but it's not as clean of process. Check with your film output company to check their recommendations since they vary.

What to choose:
24p provides the look right out of the camera of film transfered to video. 3:2 pulldown is added in the camera just as if you had telecined it from film. You can take the 29.97 directly out from the camera and edit in that in a 29.97 sequence and dump it back to video tape or DVD. Hard to go back to 24 after the edit as noted above. You can convert 24p to pure 23.98 footage by using Cinema Tools to remove the 3:2 pulldown (reverse telecine) At that point it's the same as if you shot 24pa and had removed the pulldown on capture. The potetnial downside is slightly lower quality on the mixed fields and the extra time to do the reverse telecine. 24p is good if you want the look of film motion but don't want to treat it differently in the edit and output process.
24pa provides a cleaner image since pure frames are dropped and it allows edit systems to convert on capture. (where 24p required a separate and longer process) The downside is when viewed directly from the camera it's not as smooth since some frames are duplicated. 24pa need advanced pulldown (2:3:3:2) removal to be of value. It's then in a 23.98 sequence. Once it's editied you may go out to a 23.98 dvd which will add the pulldown (3:2 telecine) or you can output it to tape with the 3:2 added.
Either one of these can go to film if desired but 24pa would provide a cleaner and faster way to deal with it.
DVD players should be doing the right thing depending on the content and the type of display.
Note that you'll need DVD Studio Pro to create 24fps DVD.

Summary:
24p (F5) is the simplest and fine for most video projects. Edit 29.97
24pa (F6) is for when you need a simple way to get to pure 24fps for Film or 24fps DVD.

The following shows the FCP setup for capturing 24pa. For 24p just set first two presets to standard DV NTSC. TimeCode on DVX100 is always recorded as NDF regardless of user settings.


Audio:
If you shoot on a DVX100 (not DVX100a) your audio will be out of sync by 2 frames. Go to your FCP extras folder on the disk and drag
DVX-100 Audio Sync Tool to /Library/Application Support/Final Cut Pro System Support/Plugins/ After capturing select the clips and go to Tool > Audio Offset to fix this. You can then edit normally. 24fps and other issues are all covered in the FCP manual. While in FCP go to the Help menu and search for 24 fps or 24p. You can also search for anamorphic or any other questions you have there.
