This hyar is an 'murican list. Now y'all better start spellin' things the righteous an' proper way, lest we send our presidential candidates up north ta muck up y'all's upcomin' election jest as bad as they done mucked up ours! > weaves in and out i.e. the man's face looks greyish, then the > colour saturates, then becomes grey again. what on earth would cause that? Hard to say exactly, given your description, but as vidiot sez the color (er, colour) and brightness are recorded the same way, unlike colour-under analog formats or even BetaSP with its separate tracks for Y and Pr/Pb. So if the color -- er, colour -- comes and goes, it's likely to be an electronics problem. I have a JVC GR-DV1u that's started to lose colour sync once it warms up: the color breaks free of the luma and starts to drift sideways across the image, wrapping back around after 30 seconds or so. Very odd... but no amount of head cleaning is gonna fix that one! Sounds like time to visit your friendly Canon service center. And take the tape along for them to see. It'll help them get to the root of problem MUCH more quickly than a verbal description alone.

You can work alternately with EditDV and FCP by maintaining two extension sets, one with Apple FW Enabler, and the other with EditDV's extensions.

I've installed EditDV on a plain-vanilla G4 or two, but you've got a hot-rodded beige G3 with a Newer G4 upgrade and a third-party OHCI card. Cruise the EditDV discussion lists and ask there if anyone has successfully installed EditDV on a similar setup. You might also check Newer for updated (I was going to say newer, but that would be redundant) drivers for the G4 card. Or it's possible that something simply got busticated (technical term for broken) when you did the first install. That the machine wouldn't boot with extensions off is a bit of a red flag -- with extensions off, you should be able to boot no matter how screwey the new software is. Sounds like something in the finder or the base-level drivers got corrupted. Try re-installing EditDV (after checking with the EditDV discussion lists on the right method for your setup) and see if the same problem occurs. Using an iMac with FCP...more - Adam Wilt I ran across support article 58636 entitled "Final Cut Pro: What kind of > hard drive should I buy?" > > It's useful but it says something very disturbing to an iMac owner. > Namely, it says that Firewire drives are not presently recommended for > use with FCP. It says that Apple is testing these drives but they have > not made any conclusions. It essentially says that SCSI is the only > correct answer. The compatibility listing on Apple's site are interesting as historical documents perhaps, but not as reliable guidance. Apple is very (overly?) conservative about what they will list as being compatible, and even beyond that they're unable to keep up with the flood of compatibility testing required. I have yet to run FCP with a SCSI drive; all mine are IDE. I'm also using a PowerBook that's too slow (officially) for FCP and DV, with an unapproved FireWire card (from ProMax), and it works quite well. Many folks are using FireWire drives, though some are having problems. Were I in your place, I'd get a big IBM or Maxtor IDE drive and swap it into the iMac, and partion it in twain -- perhaps a 4-5 Gig boot/system partition, and the rest as video storage.
