3:2 Pulldown removal does not work.
I tried all possible settings with the suggestions in this thread and it does not work. I got clips that played at 23.98 but that still had interlacing. The settings in the control panel for A frame selection didn’t appear to do anything. Interesting to know.

interlaced where? on your computer monitor or video monitor?

If you take the clip and look at it in After Effects you will see some frames that have 1 field from one original frame and the other field from the next original frame or stutter frames. To truly remove pulldown you will have a 23.98 clip which has all full progressive frames. After Effects is able to do this perfectly and I was under the impression that the BM card would do it but it’s hards to say what it is actually doing. The pattern of stutter frames is exactly like it is coming off the tape machine. It’s like it’s not doing anything at all. You do get a 23.98 clip though.

Yes it does work but it has limitations. The source tape must have continuous cadance. So if the show had earlier been edited at 29.97, you’re outta luck.
Also, you must properly identify the A frame and set your in point at the A frame (1:00:00:00 should do it 99% of the time).
You also need to be cautions using pulldown. You cannot batch re-capture only select portions of footage. So you pretty much need to capture your footage at full quality. “Delete Unused Media” in Media Manager will not be possible if you are using 3:2 pulldown.
If these limitations prevent you from working in 23.98p, then I would look into getting a Teranex.

Correction. My previous post was based on you trying to capture and perform 3:2 pulldown over SDI using either a Blackmagic or Kona card.
It sounds to me like you are doing 3:2:2:3 Advanced Pulldown Removal. This is NOT the same thing as 3:2 pulldown removal (which is 3:2:3:2 as opposed to 3:2:2:3). If your footage has 3:2 Pulldown, you do NOT use that feature. Advanced Pulldown is different. It is a rare feature found in certain DV Prosumer cameras in which Final Cut can intelligently remove it and make it 24p. I’ve never worked with it, but it’s explained clearly in the manual.
To remove regular 3:2 pulldown, I believe you just need to put the footage on a 23.98 timeline, line up the A frame to 00 frames on the sequence, and export a self contained.
