every fourth frame i get black interlace lines on things that are moving in the frame. im shooting f6 and then capturing DV NTSC 48 kHz Advanced (2:3:3:2) Pulldown Removal any suggestions?
 
yes both are 23.98 and it doesnt need me to reneder however every fourth frame i ger wierd black lines that look like interlace lines. and on the shots from farther away everything kinda jitters if i pan, and im panning real slow.
 
24p-a

24p-a

Are you sure you shot in 24p-a?

This seems like what would happen if you imported regular 24p into FCP using the 24p-a setting.

When you import 24p-a, FCP removes one frame out of five. If the footage was shot in 24p-a, FCP is discarding the "mixed" frame, so you end up with 24 clean frames per second.

Here's Adam Wilt's chart:

If the footage had 3:2 pulldown instead of 24p-a's 2:3:3:2 pulldown, FCP would still discard one frame in five, but every fourth frame would have interlace jaggies.

Check your settings, and make sure everything's set up the way it should be. You might also try capturing at 60i (29.97) and looking at the footage frame by frame in FCP to determine if it is 24p-a or 24p.

My best guess -- good luck! :thumbsup:
 
the footage i have in my capture scratch does not show the jaggies and is 24fps but when i bring into fcp i get them on every 4th frame so any help would be welcomed
 
FCP doesn't always show the true quality of images.
Save a QT of the clip, open it in QT Player and set quality to high.
Set through that. If that's fien and you don't have to re-render then the end results shoudl be fine.
 
i didnt use to have this problem but im getting jaggies even before i hit capture now i just preview it in the log and capture window and i have jaggies
