Video Flicker/Jaggies

I am using FCP on my Powerbook G4. I am trying to capture footage shot in 24P (setting F5 on th dial) to a timeline on the computer. When I capture the footage and play it back on the timeline, I get 'jaggies' on the edges of any movement. When burnt to a DVD or exported, the jaggies are there too.

I am capturing in 29.97 using the DV NTSV 48khz capture preset. I have tried working on both a 24P timeline and a 29.97 timeline and get the same result. Any movement gives me horizontal 'jaggies' on the edges of the movement.

Is there a setting somewhere I need to change? Should I be using the 29.97 sequence settings? I have field dominance set to lower...is there something I am missing?
 
Sounds like you shot 24p and not 24pa. Your footage is interlaced footage so you'll see jaggies with any movement since it's not true progressive.

You need to shoot in 24pa(advanced mode) and then hopefully this will get rid of the jaggy problem.
 
IF you're using the factory F5 setting (on a DVX100 not A or B, although I assume they are similar) your V_Detail is set to Thin which allows recording of the full 480 lines of resolution BUT with out the built in "ficker filter" that all NTSC cameras have.
In NTSC to help get rid of "aliasing" the Odd & Even scan lines are more than 1 scan line thick so that they overlap and blur the interlace flicker.

Use Thick (or Medium I think it is on 100A/B) and it will reduce the flicker.
In post you can apply the flicker filter in FCP, I would the most minimal setting that I could get away with.

BTW anyone know just how much the various settings in Flicker Filter "blur" the lines?
ie: is the minimal setting doing less blurring than running Thick V_Detail in camera?

I have a 100 and would probably use the Median setting most of the time IF I had a 100A.

The flicker filter, even at it's most minimal setting blurs the lines and gives a really 'soft' look to the video. I have tried to offset this effect with a sharpness filter.

Is 24PA a better option? I have stayed away from it because I was under the assumption that it was more difficult to work with.

Also, with FCP, should I be working in 29.97 (capture and sequence settings) even though I am using 24P footage?

I am going to do some test shots and see how it captures in 24PA. I have a friend who has the DVX as well, shoots in 24P all the time and does not experience the 'jaggies' on any of the action. He said that he often uses the 'flicker filter' in FCP but his video looks way sharper than mine.
 
I think he shot 24p F5 so there would be no pulldown right. I have been dealing with this problem for a couple of shoots now. I have had a DVX for a long time. And have shot a bunch of stuff and never noticed it befor now that I am doing alot more intence work I have noticed. I am useing a 29.97 uncompressed 10 bit squence. and I am capturing at 29.97. Should the squence be set to progressive aka no fild order??
 
There was no pulldown...it was F5...24P. I have a hunch that part of it is to due with the vertical detail and the other is a computer setting. I never noticed this in Premiere...until I started working with FCP.

Someone said that it my be the processor...and the process in capturing is slowed down causing the jaggies, but I would think that would be a random thing, not so precise like these jaggies...anywhere there is action.

Wierd.

Mabye the processor would screw it up if you were on a less capible machine, if your running something like 533mhz, but your well over the needed for SD footage.
