Odd pulldown
Has anyone seen SSSWWW pulldown? Does anyone know how to remove it, short of some tricky timeremapping after field separation?
Field separation gets rid of the interlacing, but stepping through the clip shows an odd cadence: ABCDEE. None of the pulldown schemes gets rid of all the interlacing.
I’m working with a National Geographic stock shot. The source was DBeta NTSC, but I’m not sure of the film/PAL/NTSC/HD history of the shot.
Sorry, I don’t have a DBeta deck — I’m working with a Blackmagic capture of the clip at 29.97.
Thanks,

Wow, I can hear the crickets chirping on this thread!
Ok, just to be sure here, it’s not 2:2:2:4 (ABCDD)? Maybe it was output from an NLE to Digi?
I know you’ve probably been going a little nuts for the past few hours over this one…
Have you contacted Digital Motion to see WTF is up here?
It just seems strange that you’ve got 2:2:2:2:4….it doesn’t add up.
I’m not much help here, huh?

Nope, it’s 4 singles, one double. Odd. And I have no idea what this thing was before it got to me, except that is was part of a jungle-themed assembly of 3 or 4 clips with dissolves.
I haven’t contacted NGS because they take a long time to return your calls even when you’re buying! Geeeez.
As for our simian friend, I tamed him by time-remapping the clip. I found that the count went 0-1-2-3-4-4-6-7-8-9-10-10 … so I kept the TR key at 0, then added one at 4 and 6, and deleted the last KF. Next, I dragged the KF at 6 back to 5, then added a loop(offset) expression to keep it going. It worked quite well.
Thanks anyway, Jon!

Can you say, “Animation Preset?”
I’m glad you got it going!

We get some bizarre pulldown patterns from cartoon stuff all the time, yours could have been a weird telecine or just messed up in an nle before you got it. I’m afraid the only solution we have is to either separate the fields and work at half rez or manually fix them by hand. I wish someone would write a decent plugin for this, or that after effects would deal with breaks in cadence better. Unfortunately all of the deinterlacing plugins I’ve tried assume that your source is interlaced rather than trying to intelligently recreate whole frames from non standard plugins. I was told once that the only application that could really deal with mixed cadence was Cleaner 4 (I think might have been another revision) but that the next version broke it.
Best of luck,
