P2 QT-only Pulldown Fix?

[Izoneguy]

What were your recording settings?
What frame rate do you want to edit at?

[Tyler Faison]

This project was shot at 720p24 and I want to edit at 30fps.

Thanks in advance.

If you shot in 24p then the camera did the 2:3 pulldown in the camera and already gave you a 29.97 clip for editing in an NTSC 29.97 timeline. Or did you shoot 720 24PN?

It was not 720p24PN. It was 720p24. But on a sidenote, is that what the 24PN is for? Never quite understood that.

[Lars Wikstrom]

24PN just shoots 24 frames per second with no 2:3 pulldown. So you can record 10 minutes of footage on a 4 gig card. But you need to convert with a 2:3 pulldown before you lay it to tape. Shooting 24p takes care of it for you so you can edit in a 29.97 timeline with out further conversion.

I shoot all my stuff 24PN and use After Effects to convert it with a 2:3. I find After Effects does a cleaner job.

So I guess I don;t understand your original question. If you shot 24p then why can’t you edit in a 29.97 timeline?

There appears to be a bad stagger/jitter in the playback. It’s not smooth at all. I suppose it’s entirely possible that it isn’t the pulldown that’s the problem, but something completely different. Even still, I can’t figure it out. Any ideas?

[Lars Wikstrom]

I would love to see a couple of seconds of the video to see what the problem is. You can tell if it is interlaced by just stepping through the video frame by frame. You should see 3 whole frames and then 2 interlaced frame if you are looking in an area where there is motion in the frame.

You could post one of the clips somewhere so that
we could all take a look…
Do you use the easy set-up for 720 30p???
Make sure you keep the framerate at 29.97…
Is it possible you are dropping frames?
What is your harddrive set-up?

The problem does not lie in the settings in FCP or hardware performance issues. The problem with the footage is that it was done with the “Import P2” feature in FCP BEFORE version 5.1.2, which seemed to fix the problem. I use the easy set-up “720p30” although I don’t believe it has anything to do with that.

Thanks again,

If you shot 24p not 24pA or 24pN and want to
edit in a 30p (29.97) timeline then there should
be no issues.
The removed advanced pulldown is only for
footage shot 24pA….
If you did shoot 24pA, then yes you need
to remove the pull-down and edit 720 24p.
It is hard to diagnose what is going on without
seeing the footage…..
Typically, we shoot 720 24pN and edit 720 24p….
Most of our work goes to DVD or the web and these
settings work great.
Even if we have to shoot and deliver a spot on BetaSP
we still edit and shoot with the above settings….
FCP will add the pullback when you print to tape.
