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?
