Reoving Advanced Pulldown from 1080i24PA ftg

Hi All,
Working with my new HVX200 (yay!) I've been coming across a problem with FCP's Remove Advanced Pulldown command and HVX footage shot in 1080i/24PA.

I keep getting the message "File does not contain frames encoded using advanced pulldown."

I've double checked the camera settings that it's in 1080i/24PA mode. I can see the pulldown cadence when stepping through the footage in the FCP viewer. After Effects' Interpret Footage correctly guesses the correct pulldown pattern. The problem repeats with footage imported from a P2 card or captured directly into FCP via firewire.

Any thoughts or suggestions?

Thanks!

John
 
i believe you'll need cinema tools to do the conversion. hopefully the next fcp update will support it.
 
DVFilm Maker for the Mac will do it, once properly unleashed,
so I am waiting for some sample files to test it out.

OK,
I think we have a solution. Adam Wilt was very helpful over on the SF Cutters mailing list and provided a useable process.

He said that when you select the F1-only mode in CineTools' Remove 2:3 Pulldown, it effectively does a 2:3:3:2 pulldown removal, not a 2:3 pulldown removal.

I tested it with footage from the HVX as well as test clips I made in After Effects. This method with CineTools correctly transfered both even and odd fields, despite being called F1-only. Just to be sure, I compared still frames from the original and the CineTools processed footage using a difference blending mode in Photoshop and they were identical for a set of A,B,C, and D frames from the 2:3:3:2 cadence. No evidence of recompression either.

The one downside is that CineTools produces a file that the Finder shows to be 640x360, but both QT Player and FCP show to be
1920x1080. It's a minor annoyance.

After Effects still treats the file produced by CineTools like it is really 640x360, which makes it unusable there due to pixelation when you scale it up. Fortunately AE's Interpret Footage command does correctly remove 24pA pulldown, so the original 1080i24pA files from the HVX can be used in AE directly without having to use CineTools.

Hope this helps and thanks again to Adam for his expertise.
