Here's the situation>:
Shot about 16 tapes with same camera - DVX100b - over 9 days.
Camera always set to 24P regular (not PA).
Originally digitized with Sony DSR11 pro DV deck via FW to Mac / FCP 6.0
Used regular DV/NTSC 29.97 capture setting.
I have successfully removed the pulldown later on much footage using CineTools. It did about half correct ("reversed" folder) and skipped ("skipped" folder) about half. I was able to manually select the 'A' frame in CineTools and have it remove the pulldown and interlace on about half of those remaining *original skipped files. All this footage looks fantastic (bye bye stupid interlace).
But the other remaining original and CT 'skipped' files I cannot get CT to do a successful pulldown removal on, these originally captured raw DV file are a visual mess. I have tried to re-digitize the bad tape portions with my HVX200 camera. But the footage is the same, same bad parts of tapes. I even tried to capture it in FCP using the 'Advanced' capture preset just in case the camera somehow tweaked out and was shooting 24PA mode. But I never switched it myself. And it's not 29.97 / 60i natively imaged camera setting either. It's definitely imaged with the camera at 24P (and yeah I know recorded to tape 60i). (another note, most of doc shot in daytime, but 80% of problems occur with night footage and camera usually shooting wide open and gain of 6dB - coincidence I assume?).
SO BIG QUESTION:
Why are portions of tapes showing horrible interlace "sawtoothing'" artifacts in EACH frame? With the normal recorded portions, it follows the 3:2 cadence correctly, showing 3 clean frames and two interlaced frames... But these bad parts of the tapes have interlace junk in all frames... on occasion I seem to find 1 in 10 or 12 frames looking clean but that's usually without movements. And I have checked in FCP viewer window at 100% (the way to see problems) and in CineTools.
If people are really curious about this I can post samples. I would post:
24P imaged recorded at 29.97 straight out of camera and captured to FCP without pulldown removed / modified raw capture file.
24P reverse pulldown from the 29.97 captured file using CineTools resulting correct / clean fixed file.
and a raw capture problem portion that has junk - interlace - *in every single frame.
And yes, I have tried to manually select the 'A' frame with every possible combination, and CT makes it probably look worse.
Is there any explanation for this, or even better any possible solution? Could the field order reverse on the same tape? Could FCP be reading field orders wrong? I find it very suspicious that the Sony DSR11 and HVX200 camera both result in same garbage fully interlaced looking capture on those bad portions of the DV tape. This is affecting about 20% of my footage and I am trying to finish the output of this documentary and this is holding this all up.
Thanks!!!
