Need help with Progressive PAL DV and Final Cut

[wahrez]

Hi

I have a film that I shot at 25p on the DVX. It is 100% progressive.

If I play the film in a progressive timeline I get strange wavy fluctuating lines on some horizontals.

If I set the timeline to interlaced I get no wavy lines (and no obvious signs of interlacing at 100%)

I just set the timeline to progressive and mostly everything looks great except for a few shots which have the wavy line problem. I then exported a single frame as a TIFF and there is no wavy line problem (it looks exactly like the image I see in an Interlaced sequence.


See this link for a screen dump of the Final Cut window (the added effects aren't the problem as the source footage has the same issue

See this link for the exported TIFF from the above sequence

Exporting the movie to a QuickTime H.264 or DVD produces the problem unless I go to Interlaced...What do I do???

Thanks
Bruce

A little more background.

I've converted the footage from DV to ProRess422 (but have tested the original DV source footage and get the same problem).

I'm using Final Cut Pro 6.0.6 (get the same problem in previous versions and a test I did in version 7)


To illustrate the problem I have uploaded three sample clips:

An output of the above Progressive Sequence to a TIFF sequence and reimported as a TIFF sequence into a Progressive sequence
