ALERT: Power OFF before changing Firewire or switching HDV/DV

Thanks John!

Then what about the ferrous core magnets. Should the isolator go at the computer end or camera, or is there any difference?

There is already a large sign posted (by me) at the editing desk...."POWER DOWN DUMBA**" I need these kind of reminders or I get sloppy.

I have firewire cables with and without the magnets. The magnets that came with the JVC Camera seemed particularly pointless as they weren't wide enough to loop the cable through - if you can't loop the cable then they won't work. The cables that came with magnets have them at both ends.

Run off battery and use a decent surge protector /power filter on all your PC and hifi gear. Use your isolator and follow the protocol (the idea of the isolator is actually to give you hot swap capability but I wouldn't risk it). That should keep everything clean and safe.

All the firewire cables I've seen have magnetic suppressors at both ends. The point of the magnets is NOT to suppress shorts, but, rather to suppress RF interference. They won't do squat to save your firewire bus from a short.

Ahhh thanks John, I thought I was having a bad day when I tried looping the cords through tiny core's

Ive got a couple of firewirecords without magnets (unless they are built into the flat housing) so Ill go to my Bundles n More guy and get some good ones. Still gotta find one of these isolators, two if one for my laptop as well....

We just blew the port on our GY-HD100 with a Firestore. With these units, we are plugging and unplugging constantly. The operator may not have noticed the camera was on. I just have no idea.

Is there a cable M/M out there without the voltage pin active? Would that work. The port isolators here look like M/F adaptors.

o.k., I think I may have blown one of my ports. One of my GY-HD 100's doesnt connect via Firewire anymore. How much is the fix?

$1995 , I paid $1395 couple weeks ago after the discount .good luck

Randy Johnson · January 4th, 2008, 12:58 PM

$2,000!!!??? are you kidding me? Well I guess im using tape. I cant pay that. I was going to get a on board HD but not now. Thanks.

the same thing i said until i got the discount .

Randy Johnson · January 4th, 2008, 03:21 PM

Im not worried about my home system, I planned on getting the Firestores next year. Im more worried about blowing the port in field. If got that cable would that eliminate the poetential for that problem? I can get a 4 pin Firewire card for my home editing system too if it will help. So this is from the power in the computer? or the camera? or both?

Brian Luce · January 8th, 2008, 06:58 PM

I haven't blown my report, but I'm getting paranoid that I might!

What does it take to caputer through component? a 500 dollar card? If so, and if I blow mine, I can't see paying $2,000 for a repair. The camera is barely worth that.

Randy Johnson · January 10th, 2008, 09:59 PM

Sorry if this has been menotined. I called Firestore and they told me that the FS-4 has 2 Firewire ports 1 for shooting and 1 for File transfer. The 1 for shooting even though it is a 6 pin does not carry power. I dont know if this helps our situation or not.

I'm considering the purchase of a GY-HD200U, and my rep mentioned the fried firewire issue. He recommends using a Kramer PT-1FW spark arrestor. I'll probably velcro the thing to my Firestore. http://www.fullcompass.com/product/316180.html

No, this isn't an ad for Full Compass, I'm just buying the unit from them.

While we're talking about the 200, I'm really hoping you guys can answer some questions:
1. I like what I'm reading about the HD200, it sounds like a good unit. However, I need to know if it can be tweaked to closely match a Panasonic AG-DV200p about 3-4 times a year.

2. I edit with Xpress Pro, and Avid tells me it'll accept 720p/60 from the HD200, but I can't find the camera on their list of approved devices. I read on a forum that the camera must be connected to the host firewire port instead of the Mojo during capture, but can anyone out there confirm success in getting Xpress Pro to communicate with the GY-HD200U? Were you able to batch-capture? Any tips, tricks, or warnings for me?

3. Lastly, has anyone tried putting the HD200 on a Manfrotto Fig Rig? Was it worth the expense?

Looking forward to your input.

thanks.

I just learned my lesson. I apparently blew the firewire port on my Sony FX-1. I was using this camera as a deck (besides filming a lot with it) and constantly unplugging and plugging it into firewire ports on two different computers to capture. Any way to fix it for a reasonable price, or do I just have to send it to Sony and see what ridiculous price they quote me? I can probably just buy a new camera for whatever they will end up quoting me.... sigh

Reid Bailey · January 26th, 2008, 08:18 AM

Just a note about the Kramer PT-1FW.

I got bought one from B&H and tested it with HDV signals. I shot at both HDV 30P and 24P and everything seemed to work fine. The footage looked and I didn't see any dropouts or new noise.

I only shot about 2 minutes of my cat, but it does seem to have passed the signal normally.

Okay, I do have to admit that I had a bit of a panic meltdown, when after I changed the scene file to 24p and the camera rebooted with drive still on, it wouldn't record to the drive anymore. I thought for sure that I'd blown the port. After much hand wringing I realized the 1394 trigger mode was never set in the new scene file.
