Capturing 24p in FCP HD

I am terribly ignorant and was just curious if I need to do anything special when logging and capturing my 24p footage into FCP HD- I haven't changed any settings and the footage looks great but I want to remain cautious. Any changes in regards to pulldown, etc. ? Thanks for your help!
 
Naw, in 24p mode it does the pull-down for you to regular DV. So in FCP you capture it simply as regular DV footage like you always do.
 
Hi - new member here. Just wanted to say that this place is an absolute mine of info and is proving very useful in helping me to get started with making a short.

Back on topic - does BenB's answer hold true for PAL cameras in 25p?

Hi msm,

In regards to 24p and Final Cut, if you shot in regular 24p, then yes you just capture the footage as you would capture any other footage. The 3:2 pulldown was done in camera and therefore the footage you are capturing is really 29.97 fps to fit in with the standard 29.97 NTSC timeline that is default in FCP.

If you shot in 24pa, then its a little different. 24pa uses a 2:3:3:2 pulldown cadence to lay 24p as 29.97fps on tape. In FCP, you use the capture preset DV NTSC 23.98 48khz. This preset will allow you to reverse the cadence to extract the original true 24 fps and allow you to edit as such. But you have to make sure that your sequence is also set as 23.98 fps and not 29.97 fps.

Hope this helps,

So really.. what is the benefit of using 24PA? Easier output to film & DVD?

Thx for the input..

Exactly!

Think about it .... with 24pa, you can extract and edit in a 24 (23.98) fps timeline sequence, hence have your final product as such. You can do an easy transfer to film or create a 24p DVD (this also allows you to encode at a higher quality as there is less info to encode from 24p as opposed to 29.97i). I always work in 24pa as opposed to 24p as you have more versatility.

Best,
 
Yes, the DVX does the pull-down internally and write to it's tape regular DV format.

You can use Cinema Tools with FCP-HD to reconvert back to (for example, in NTSC) native 24p that will include the original 24p frames.
 
I never shot in 24PA. Just 24P.
But I edit in a 23.98 timeline.

What you have to do, capture the footage as DV Firewire. It will go into the 29.97 and you can edit off that. But if you want to edit in the 23.98 line, you need to batch reverse telecine your footage.

Open up Cinema Tools>reverse tele>pick the folder where your capture is.. and let it fire away.

Drag the new files into FCP 23.98 timeline and edit away. Now you can extract any frame you want without having to worry about interlacing. However, when you export to 24p DVD, it will definitely show the "jerkiness" vs. a smoother look from 29.97. (That IS if you export an mpeg2). However, I think a quicktime export from a 23.98 timeline will export a 29.97 movie.

See pages 45 & 90 of the DVDSP3 manual.

Though what WaveRiderXIX said does indeed work, if you intend to edit in a 23.98 timeline in FCP, then you should shoot 24pa (2:3:3:2 pulldown cadence). The purpose of the advanced mode is to allow you to revert to a 23.98 sequence for editing in a 23.98 timeline. Regular 24p does the standard 3:2 pulldown, which will be fine for editing on a 29.97 timeline, but if you intend to edit in 23.98, you will have to bring your footage into Cinema Tools and do a reverse telecine, in which you will incure a generational loss in quality due to having to recompress frames. By shooting in 24pa, you can do an advanced pulldown removal upon capture and retain your 23.98fps in full quality ... no loss whatsoever.

Hope this helps,
