  Panasonic Varicam 24p and PPro2 question

  Posted by Matt Stalker on February 6, 2007 at 9:09 pm

  Hi,

  I am capturing Panasonic Varicam 24p footage into PPro2 via HDSDI through a multibridge extreme. When logging clips, it seems that PPro2 is treating them as timebase 29.97fps. From the little I know about Varicam, that’s not entirely unexpected.

  After I capture, PPro converts the TC to 24fps, which is correct. Only problem, the marks I (or usually a producer) logged have now changed to reflect the 29.97 to 24 timebase conversion. My question is this: How can I most simply deal with this issue in a workflow that would entail a producer giving me exact marks from the tape, before the software conversion?

  Any additional light anyone could shed to help me understand exactly what is going on under the hood in the Varicam format would also be appreciated.

  Thanks,

  Matt

  DVC ProHD format on the Varicam is 60p…all the time, all the way.

  The different frame cadences that the Varicam can do are based on interpolation or frame duplication. Shooting 24p (hopefully you mean 23.976) on a Varicam means that there is 2 copies of one frame, 3 of the next, then 2, then 3 and so on.

  Depending on the deck you are using, it may play this back as 29.97 with a pulldown. Depending on just what order everything happens in and what the BM card is doing with the TC, it has potential to be a real pain in the neck.

  I work with CineForm/AJA and I can have CineForm extract the pulldown on conversion, but i have no meaningful experience with the Black Magic products and I’m not sure what options are available to you. maybe their tech support folks can offer a preferred workflow for your situation?

  Thanks for the response Tim. Yeah, it seems like a strange format that’s tripping people up around here. I’ll post back here what I learn from the experience. I’ll be importing the Varicam footage into a 24p project in PPro2, then I’ll send it over to After Effects for compositing, and then it will end up in an Avid for finishing. I want to hammer out the timecode issue to make the process as painless as possible!

  Thanks,

  Matt
