So you're talking about the computer -> drive connection? I don't know how often that's an issue... the camera-laptop connection is the one I'd likely want to stretch as far as possible...

Right; I'm just saying there's other ones that do the same, and other approaches (e.g., USB power stealing...)

I found the answers I need, so nevermind.

Ferrite Cores

Hey Robert,

Hope your latest shoot went well.

Quick question ... where to find ferrite cores ... I seem to be hitting a roadblock in acquiring them (other than stealing off of all of my other gear :o)

I get them from Digikey (www.digikey.com). You might want to download the ZCAT-type PDF from TDK first. Ferrites come in various sizes based on outer diameter of the cable it's going on and, the RF reduction value the core is designed to work with.

Here are 2 TDK part numbers for the cores I use the most:

- ZCAT 2035-0930-BK
- ZCAT 1730-0730-BK

They also come in two colors: grey and black. The "BK" identifier at the end of the part number is the black version.

If you can't make sense of the TDK part numbers in the PDF catalog shoot me an email or give me a call and I'll walk you through how to get the right size ferrite.

Here's the address for the TDK PDF catalog of snap-on Ferrite Cores: http://www.tdk.co.jp/tefe02/e9a15_zcat.pdf .

Robert I do have one question on the LaCie card and recording with my two HVX200's. I ordered two LaCie FW800 cards for the two 15" old/new 1.67 gig processor and 1.5 gigs of ram Apple PB G4's, to run out to the OWC 500GB RAID drives, but I don't understand how the LaCie's have their own power supply. (I'm not a geek, just a 57 year old guy who is doing a movie based on one of my short stories and I've got a lot to learn in the process.) I've checked the ads and this forum as well as the DVX forum and found no mention of an independant power supply for the card. I plan to plug in the power books when I'm shooting and was wondering if the card draws power from the PB or what? Thanks.

The LaCie comes with a wall-wart power supply which connects into a side socket in the card itself. It will make sense when you get the cards. However, there won't be any need to run power to the LaCie card since the external drives have their own power supply.

Using external power on the card is for those times when you are using a device that actually draws power from the FW bus itself. It's not required if the device has it's own power.

Thanks Robert. I thought that was the case, but as I said I have a big learning curve ahead of me equipment wise and I appricate the reply.

Robert or anyone,
When recording directly from HVX to Powerbook via firewire in FCP using capture now :
Is there any wat to get the cameras timecode?
Every clip I get starts at "O" regardless of the camera settings even with camera at Freerun.

If you can't get the cameras timecode, how have you been setting a new or alternate timecode on your clips?

David M. Payne March 2nd, 2006 10:54 PM

this thread should be a sticky IMHO. Thanks for the info Robert and prehaps you could help me on my other thread.
