More questions (HVX200): Firewire transfer, 2:2 pulldown, field dominance
Hi all:
After my previous post, I have some further questions about the workings of the HVX-200 that I couldn’t clarify by searching through this forum:
1) Today we tried transferring the contents of a P2 card through Firewire to a Mac (since we didn’t have a PCMCIA-enabled laptop handy). We followed the steps of the manual: plug the camera into the computer, turn it on, set “1394 DEVICE” in “PC MODE”… but the Mac just didn’t see the camera at all. We also tried opening the Disk Utility to mount the card manually, but we didn’t even see the card grayed out in it, as the manual describes. Is there anything we’re missing? Is there a specific order in which we must turn on the camera/plug it into the Mac/set “1394 DEVICE” in the menus? We’re using a dual G5 with OS X 10.4.
2) A terminology question that I’d like to clarify: when the manual and related docs talk about “2:2 pulldown”, they are referring to the way that the HVX-200 records 25fps footage in 720P: i.e., it actually records 50fps in the card, and then, when editing, it shows only every other frame. Is that it or am I getting something wrong? And if that’s the case, why is it called “2:2 pulldown”? Maybe it’s because I’m not a native English speaker, but what the camera does in this case doesn’t seem to be related to the pulldown operations that I know about (2:3 and so on).
3) I know now that the camera can record in SD in progressive mode… but, can it record in SD interlaced mode, with *upper field first*? Today I had the chance of reviewing some SD footage that had been giving trouble to a colleague when importing, and part of it was progressive, while some of it was interlaced… but with upper field first, which goes against anything I knew about DV (wasn’t it always “lower field first”?). And yes, I’m sure it was shot with a HVX-200.
Thanks in advance,
Paulo.
