Why does 50% look better than 100%?

i just tried an experimented. i changed my easy set up to NTSC 23.98 fps, DV NTSC 24p (23.98) Advanced Pulldown Removal. captured some footage at 23.98 with advanced pull down removal. put a clip onto a 23.98 timeline.

here, every frame looks perfect, if i scrub through it. but on PLAYBACK, i see the lines. but this is in FCP, so i exported a quicktime mov (i dont have an external monitor), burned a dvd, and tried it on my tv. same thing, still see the lines.

i feel like i'm soooooo close to figuring it out but not sure why playback doesnt look like it does when i scrub through... (or just hit right arrow and go frame by frame, where it looks perfect as well)..........
 
You SHOULD be able to remove the advanced pulldown from the browser window of FCP. Maybe you didn't 'select' it.

Select the captured clip as it appears in the browser window. Then go TOOLS - Remove... etc.

Now, about your experiment:

Where are you seeing these lines? I still don't see a good explanation of what these lines are you are seeing. They're the SAME lines you are seeing before you pulled the cadence?

First, understand this: The DVD will automatically add a cadence BACK TO the video as it plays out of the DVD. EVEN if the DVD is encoded properly at 23.98 fps. Your NTSC monitor just won't handle 24, it needs 30fps.

SO, let's make sure we did this correctly first. THEN we should decide if it is something we should really worry about.

1) Select the timeline
2) File - Export - Current Settings - (Non self Contained)
3) Open Compressor
4) Drag that saved file into Compressor
5) Choose from the options to compress that file... Mpeg2 High Quality 90 minute and then ALL.
6) This will give you THREE files, m2v (video) .aif (audio (Throw it away) and .ac3 (compressed audio for DVD)
7) Open DVDSP
8) Drag the m2v and the ac3 into a track asset and burn.

Now lets go back to FCP.

(we're still on your experiment sequence)

Set your canvas window to 100%... drag the windows around so that you don't see any scroll bars in the canvas window. THIS ensures you will be seeing ALL fields.

Press play.

No 'lines'? Ok fine. Then you have nothing to worry about with the 'lines' you are seeing when you burn it to DVD.

These 'lines' are a natural fact of the NTSC monitors scanning down every other field and up the missing ones (or up and down) every 60th of a second. There is NO getting around how the TV draws the screen. Your computer monitor just flashes pixels... there isn't a drawing 'gun'. That's why you don't see 'lines' when watching it on the computer monitor.

Is this starting to make sense?
