Pulldown Removal
We shot film for an open to a show, 24 frames and the film transfer added pulldown to make 60i to HD cam tape, the tape was played and recorded to the new Convergent Design Flash XDR @ 100Mbps using the XD Cam quicktime conversion. The file is recognized in Final Cut as XD CAM HD422 1080 30p. I want to now remove the added frames as we need to work with just the original 24 frames for all of the compositing in this shot. Yes I know I shouldn’t have had the film transferred to 60i but I can’t afford to spend 5 more hours re-transferring and color correcting this again. I need some help.

Hey Michael.
Reverse Telecine in FCP not work? What about Cinema Tools?
And when can I borrow that thing from you?

Cinema Tools gives me an error, this movie has temporal compression. I really don’t know how to use this program.
I sent the XDR over to Panavision -
Might be something in the way the unit recorded the footage…reverse telecine not possible because of this method it uses.

I don’t think you can do pulldown on gop (HDV, XDCAM, MPEG2 etc..)based footage.
It has to be frame based. -
You’re right, I transcoded to Pro Rez then I can use Cinema Tools to remove the pulldown, I’m still not sure of the proper setting but the best so far was capture mode Field 1, Fields A. And now I’m testing Smooth Cam on the clip as well as Topaz Enhance Clean RGB filter to fix the faces from grain.
Good Luck

You’ll have to guess since it began as GOP encoded material.
It won’t be the same as if it was just a quicktime dvcpro-hd or uncompressed
file.going through xdcam changed it kinda like flattening a .psd and saving as a .jpg.

Don’t do that. “Capture Mode” should be “Field 1 – Field 2” although I work in NTSC not 1080i so it may be “Field 2 – Field 1” for 1080. Try both but don’t use “Field 1” as that probably throws away half the resolution.
For “Fields” choose Style 1. There are five choices. Whatever frame the playhead is parked on, it will assume that what you choose here. 3:2 pulldown has 3 progressive frames followed by 2 frames with mismatched fields. Park the playhead on the first of the mismatched ones during anywhere in the video. This is the “BC” frame. So then choose “BC” and you’ll be good to go.
Note that if there are timecode breaks, or the footage was edited at 60i in any way, then the 3:2 pattern (cadence) is broken so the pulldown can no longer be removed with Cinema Tools. You can try JES Deinterlace which does the same as CT but detects cadence breaks (as long as there aren’t too many close to each other). If that doesn’t work you’ll need to use Compressor which analyzes each pixel to fix errors (this takes a VERY long time). Last resort, take it to a place that has a Teranex, although I’ve found that’s not always flawless.
As I’m sure you learned by now, you should have mastered that hdcam at 23.98 PSF.

Wow this worked great, I now have the pulldown removed from your instructions. It was one solid clip and I used Capture Mode setting Field 1-Field 2, Fields setting Style 1, _BC_ setting placing the curser on the first of 2 mismatched frames. Thank you very much you have really helped me and my production of Faithful Friends.
