  • How do you make 3:2 pulldown removal work?

    Posted by Robert Brown on April 11, 2006 at 9:59 am

    I have 29.97 1080 UC footage that is originally from a 23.98 camera. I am trying to remove the pulldown with a BM HD Pro card in FCP. What settings do I use? Nothing I tried worked. I can bring it in 29.97 but the pulldown is obviously still there. If I put the Capture frame rate at 23.98 it doesn’t see any video coming in. There is also no information that I could find in the documentation. I did find the frame offset but it didn’t seem to do anything.

    You capture at 23.98 and use cinema tools to perform the pulldown.

    I can’t say for HD… but in SD you make a 23.98 capture setting (duplicating your 10 bit NTSC setting and switching the framerate to 23.98) and then simply capture starting on an “A” frame (A, B, jitter, jitter, D)

    Thanks for the tip but it’s not working. You’d think BM would have some info as it’s supposedly a feature on their card.

    Well this method also worked for our AJA Io boxes – and since they’re just dumb hardware, it must be a FCP thing. I know in the BM system preferences, there’s a dialog about 3:2 removal… but have no idea how that works. Your best bet until then it just to capture 30fps, and have Cinema Tools or After Effects strip the 3:2 out

    Hi Robert,

    Use the “Blackmagic HDTV 1080psf 23.98” easy setups to cnfigure your project. Once that is selected, you need to open up the capture preset settings (cmd-opt-Q) and change Input under “Qucktime Video Settings” to “HDTV 1080i 29.97”. Your system will now see the input and capture it to the 23.98 timeline.

    regards

    I’ll try it again tomorrow. Don’t you guys think you should have something about this in a PDF file?
