Panasonic hdx900 24p-mode FCP workflow
Hi,
for our feature doc we shot with a hdx900 in 24p-mode, not 24PA. Using a Panasonic 1400 deck most of the footage was captured through a black magic card over SDI resulting in 23.976fps DVCPRO HD movs with 48kHz audio.Now we want to use the camera to capture over firewire to save the cost for renting the deck and get a bit by bit exact copy, since we edit in DVCPRO HD anyway. But since we did not use the 24PA mode we can not use the advanced pulldown removal during capturing of FCP. So we use Cinematools for the pulldown removal, but its not always working. There are interlacing comp artifacts visible in some of captured files.
Does anyone know a better workflow or better program for the pulldown removal? Help would be very much appreciated!
Thank you
Felix

Just copy the files you already have. They will be bit for bit the same of course.

Hi Jerry,
I didn’t made myself clear, I think. The pulldown removal of cinematools is not working for about half of the tapes. It can not detect the 2:3:2:3 series perfectly. Do you know one?
Thanks -
I meant to say, does anyone know a reliable software pulldown removal?

Doesn’t the that camera have an SDI out? Why not capture through the decklink as you did before?

As I understand it, the capture of the 29.97 fps is not the problem. Over SDI or Firewire would work, though only FW gives the bit exact copy. Using SDI would only mean to decompress the DVCPRO HD stream and recompress again. Only if we would go to a different codec, going through the BLack Magic card over SDI would make sense, does it?
But again, thats not the issue. Getting a perfect 2:3:2:3 pulldown removal in software, without a deck is. Some of the by cinematools processed files have interlacing artifacts. The field pattern for 24p was not found, I assume, and wrongly combined. (We did not shoot in 24PA)
Do you know the answer?

Felix, did you find an answer for a better pulldown tool? Just coming to a project with what seems like the same problem. Similar issues are going to have to be confronted.

Hi Matt,
I found compressor always found the pattern and recompressed to dvcprohd. Also its batch processing makes it convenient. If you are a purist, you would go uncompressed or at least to high bitrate dnx or prores, if you don’t have the resources. So use the reverse telecine function and audio passthrough.
I hoped for a solution where I don’t have to recompress, but thats not working for 2:3:2:3, since there is also some deinterlacing requiered, for one frame, I think…
