Setting up to edit 24p advanced mode...

So far everything that I have shot and edited on FCP4 has been shot using 24p Normal. However, I want to learn the process of removing the pulldown for a 24p timeline, etc.

Can someone walk me through the process. I hook my camera up via firewire. Now what? I know have to go into my FCP settings and select some things like capture preset, sequence preset, and playback control I am guessing that I select the DV-NTSC Advanced 2:3:3:2 pulldown Then for Sequence - DV NTSC 48Khz-23.98 as well as playback control?  I make these selections BEFORE I capture video right?

Okay I have read past posts about people that have had jerky or jittery footage when editing with 24pA. How do I avoid this?

Also is Compressor only to be used if I am using DVD SP? Will it work with iDVD as well?

I have shot some footage in 24p normal mode with custom camera settings. I just imported all that in the computer, If I had set the normal footage to edit in a 23.98 timeline would that screw everything up big time? I left it in a 29.97 but I was just curious.

My next project I want to shoot 24pAdvanced and edit removing the pulldown.

Oh yea the book says you can add the pulldown when your project is finished but doesn't say how to do it. So how do I do that since I am asking a boat load of questions today! :)

Hi DVX100Shooter (man, I sure do have a hard time calling people by these user names, it's like being in a fraternity with bad pledge names... maybe we just need to drink more ;)) - quite a few questions squished in there but here goes...

So this previous material you've just edited as 60i (pulldown left intact) on a 29.97 timeline right?

Thankfully, in FCP4 this is pretty effortless. Hook up your camera, put it in VCR mode and load up tape as normal. Open the Log & Capture window, click the Capture Settings tab. Select 'DV NTSC 48 kHz Advanced (2:3:3:2) Pulldown Removal' from the Capture/Input menu. This tells the program to ignore the dupe frames in the footage, thereby eliminating the pulldown and going from 29.97 to 23.98 on the fly. (If you will be capturing most or all of your footage this way, you can set this Capture Preset as the default under the 'Audio/Video Settings' preferences.

Upon capturing your footage it will now be at 23.98 fps. Createa new sequence - chances are this is still set at standard 29.97 DV. With the sequence either selected or open, choose 'Settings...' from the Sequence menu. Click on the Load Sequence Preset button and choose 'DV NTSC 48 kHz - 23.98'. This will set your sequence at the correct timebase and should set the field dominance to 'none' - which is what you want for the progressive footage from the DVX100. This 23.98 Sequence Preset can also be set as the default under your preferences.

At this point the footage should play normally in the timeline and require no rendering (unless of course you've applied effects, etc.)

Not sure what they're referring to here. It may either have to do with the pulldown playback - as noted below - or as with film, if you pan / move the camera too fast you will get strobing at 24 fps.

Also is Compressor only to be used if I am using DVD SP? Will it work with iDVD as well?

As far as I know iDVD won't take in any .m2v files that weren't created by it, so yeah, you'd need to use Studio Pro if you wanted to take advantage of Compressor's dual pass compression or have a program longer than 60 minutes. I don't know if this changed with the iDVD 4 or not.

I have shot some footage in 24p normal mode with custom camera settings. I just imported all that in the computer, If I had set the normal footage to edit in a 23.98 timeline would that screw everything up big time? I left it in a 29.97 but I was just curious.

To edit this 'Standard Pulldown' material in a 23.98 timeline, you will of course need to remove the pulldown first. You can do this with Cinema Tools, which is now included with FCP4. Once you've done this you can then mix footage shot in Standard or Advanced pulldown.

Depending upon the speed of your computer you will have a couple of pulldown playback options listed in the menu at the upper left of the timeline. These only apply to viewing the footage on an external (ie - NTSC) monitor. '2:2:2:4' is just a rough pulldown for viewing the progressive footage on an interlaced monitor without taxing the cpu too much. (This will look 'stuttery' on playback.) You'll never use this one for any sort of output. The next one up, '2:3:3:2', is the same as the advanced pulldown that the DVX100 produces. Some people use this when archiving their edits back to DV tape. '2:3:2:3' is the standard pulldown you want to use when playing out copies of the edit for NTSC interlaced display (ie - VHS tapes, miniDV for TV playback, possibly for DVD depending on use.)

As far as I can tell, FCP4 only allows you to add pulldown on playback (or Print to Tape, etc) from the timeline. That is, you cannot export a Quicktime file with pulldown from FCP. You output a 23.98 file and then need to add pulldown with some other utility after the fact if needed. So to get pulldown from your 23.98 timeline, you will need to select '2:3:2:3' from the playback options (depending upon your computer, you may need to play around with your realtime settings to make this available) and then render the entire timeline with this setting intact. You can then play this out to tape.

The only other thing to look out for, that you may already be aware of, is that you will still need to account for the audio drift when shooting at 24p. FCP4 now has a utility for this, but I've found it to be a little buggy, and usually just manually sync it up if something like a clapboard is available and relink the video and audio. (The FCP4 utility unfortunately doesn't positively identify if the audio fix has been applied to a clip or not and it seems to be a little inconsistent in how it works with clips between the browser and the timeline.)

Hope this all helps - good luck on your project,
Clayton
 
Re: Setting up to edit 24p advanced mode...

Here is a question that hopefully can be answered quick so I don't have to start a new thread.

What's the difference between 23.98 and 24? I know when we speak of 24fps we are actually referring to 23.98, but in FCP there is a 23.98 timeline option and a 24 option. Why is this? And what is the difference?


I have figured out my own answer...

23.98 is NTSC 24fps. 1% slower than 24fps. True film runs at exactly 24fps, while NTSC video of film runs 1% slower than 24fps which is 23.976 to match the 29.97 fps of NTSC video. Which was done to alternate frequencies or something back in the 50's when they were broadcasting.

Hmmm...I guess I should be running everything at 23.98 and have it be sped up if I make a film transfer. Excellent, thanks for the info cole!
 
Re: Setting up to edit 24p advanced mode...

I'm in the same boat, need additional assistance. I'm shooting 24p advanced, and will probably end up burning it to a DVD, but if the thing turns out well, might transfer to film. Does it make a difference how I capture, or can I just use the settings set out in previous posts on this thread?
 
Re: Setting up to edit 24p advanced mode...

dhffhd,

from what I just learned, if you are even thinking about going to film then edit in true 24fps. When you burn to DVD you footage will slow to 23.98 which is a 1% difference. It's unnoticable. But from what I just said theoretically you could just edit in 23.98 and then when you transfer to film your footage will be sped up to 24fps which is 1%. sooo...I don't know.
But what I learned is here
