New Workflow From Apple

There is no issue. If you understand how disk files work, you will be puzzled by this thread. Don't be impressed by the word "Checksum". In this context, it is not relevant. Creating a disk image (DMG) each time is a huge, huge waste of time and will gain you no more safety than simply copying the files. There is no issue.

Not that I don't believe you as I personally feel that if I drag a file from one volume to another the copy it creates should be bit for bit identical to the original every single time. But the fact is we have people who are losing files during transfer and in the case of a lastclip.txt this can be extremely detrimental. So even though there SHOULD be no issue, there is, and we're trying to figure out a workflow which can limit the chances of a computer hiccup dispelling our footage into the ether. Can you please explain further why verifying the files after they've been copied or creating a disk image so we're not changing filesystems on the copy or anything that we've been talking about is a waste of time, please. I'm all for saving time while achieving the same or a better result.

It's not extremely detrimental, it's just annoying. The LASTCLIP.TXT contents is duplicated in the XML file of every P2 card CONTENTS folder. So if you lose LASTCLIP.TXT, you can just look it up the information in the CLIP file. If your editing software insists on it, you can recreate the text file. (I don't think it's been established here which editor it is that requires LASTCLIP.TXT. Anybody know?)

You said it. The only problem the DMG approach has been touted as a remedy for is "people who are losing files during transfer". Exactly my point.
 
We are presently evaluating a HVX202, as far as I can tell thats the PAL version of the 200. All the settings are either 50i or 25P which you would expect .
The problem is FCP only seems to support one setting, 1080i 50P nothing else works. Is this a problem with Apple or are we doing something wrong?
When we shoot 1080i 25P (the camera does not support 50P) it puts it in a 1080i wrapper and manages it fine.
We also want to shoot at 1088i @ 24P to match the world market, it does not appear to do that either.
Thanks in advance for any assistance.
 
I'm currently AC on a short being shot on the HVX200. We've been downloading our P2 cards first onto the P2Store (AJ-PCS060G), then plugging the cards into a PowerBook and copying them (not creating disk images) to an external hard drive. We seemed to be having some problems with the files copied via PowerBook , so I set out to create disk images of the volumes on the P2Store after reading Mr. Deveraux's post, using a Dual 2GHz G5 wth 2GB SDRAM running OSX 10.4.7, copying to a LaCie 250GB connected via FireWire 800.

The good news is that the P2Store footage was already backed up by standard file-copying. Now for the bad: About a minute into creating a disk image of the first volume, the copy failed, the drive disappeared, and now the P2Store displays LED error codes that the manual translates as: "There may be a problem with the unit. Contact the place of purchase." Attempting to copy a P2 card onto the unit results in a SMART error. I have not tried re-formatting the P2Store yet.

I had assumed that creating a disk image from the volumes on the P2Store's hard drive would work the same as the technique Mr. Deveraux described for P2 Card copying, but right now it looks like it doesn't. I suppose it's possible that the P2Store hard drive was defective and happened to fail at that moment. This is[/] it's first job. Tomorrow we'll start trying to trace the problem with the P2Store.

Anyone have any input on this?
 
A little update:

I talked to Panasonic tech support about the P2 Store and, given the error codes I was getting on the unit (5 blinking red LEDs when I pushed the HDD status button and a SMART error when I tried to download a P2 card), he thought the disk was damaged or defective. Later that day, the DP hooked the P2 Store up to his Windows machine, played the PC/MAC switch "chord" for ten seconds or so, and the unit woke up, went into PC USB mode, and all 15 volumes mounted on his machine. And apparently nothing was lost. We're using a different unit this weekend nevertheless.

So we don't know at this point if the attempt to make the disk image caused the crash. Could the problem be the fact that I was copying a partition? I haven't communicated with Apple, but can anyone see any inherent danger in using Disk Utility in OS 10.4.7 to make a read-only, uncompressed disk image of a partition on a USB hard drive (the P2 Store) - copying to a FW800 external drive?

No. I highly doubt anything in software caused the problem, because you were only reading the P2 Store, not writing any information to it. Think of it this way: What if you had locked the P2 Store by making it write-protected? So nothing could possible write to it? You could still create a disk image with it.

Not if hardware behaves as it should. The only thing that could mess up this process is a hardware glitch (power surge/outage, bad platter, dead battery, etc.).
 
I have had the same error making or trying to make disk images from the P2 store. Sometimes it works fine. sometimes it just won't go- and you get the 5 red LEDs of death. Power down the p2 store reboot- all stuff is still there, but some sort of arcane communication between mac and p2 store went awry. Interstingly I had it happen twice on a partition, only later able to make a disk image of it. Why was I trying to make a disk image? because when I copied using P@ genie software the "video" clips in the video folder dissapeared in the ether and never made it to hard drive! I am beginning to wonder if it is a coincidence...... (In p2 genie- copy fails but keeps going and does not alert you, in disk image whole thing comes crashing down, and at least you know something is wrong, just a theory)
Stay tuned for my Panasonic p2 store/ mac rant, coming soon...
 
I'd be interesed to hear other peoples expierences- are you having the same problems? Is it just a few people, or LOTS of people? Is it just with the P2 Store, or with the cards as well?

I've been using my laptop (G4) with P2 Genie unloading my cards to the HDD, and then burning the folder to DVD- no DMG file. And it has been working fine for me- no issues yet. (Crossing my fingers.)
 
Sounds like you are using 4 gig cards? How much footage (in terms of hours run time) have you run through your workflow? I have had somewhere around 10 hours before I had my fist problem
 
that is FIRST problem. Fist problems show up around the time you start punching walls in frustration :)

Grab yourself a copy of P2 Log. It comes with a DVCPro HD codec that will allow you to work with the other formats not supported by Final Cut Pro.

http://www.imagineproducts.com/P2log.htm

We are using it with our 202 for shooting 720p25pn footage with all of the variable frame rates, and it work s a treat. (Imagine are also doing a deal at the moment where you get it for US$99 instead of US$199.

Cheers

Still making images?

Still making images?

So now that it has been a while are MAC users still creating disk images of their P2 when ingesting?

Have there been issues with this tecnique versus just copying the contents folder?

I am trying to find the best/safest way of ingesting P2 into my powerbook/macbook for cutting in Final Cut Pro.

The disk image procedure was to help insure that all data was transfered properly but I believe with panasonics releasing the free P2CMS program which does a verify of the footage dowloaded the disk image procedure is not necessary.

I have since stoped using the disk image workflow. I had one corrupted disk image and gave up on it. I don't have any problems with copying the contents folder and I've been doing it that way for 1 1/2 years.
P2 Genie rocks, but I think it is off the market at the moment.
There is also the P2CMS application from Panasonic...
https://eww.pavc.panasonic.co.jp/pro-av/sales_o/p2/cms/index.html
 
I too have been using the P2CMS ap and am extremely pleased with it. The only issue that remains for me is the P2 card at times not appearing on the desktop, requiring a reboot. I'm about to wipe a Powerbook G4 1.25 and install only workflow aps (P2CMS, FCP) in order to have a stripped down field solution. Not to revive an old post here, but does anyone know if this bug was ever resolved?
 
Hmm, how often does that happen?

I don't really have the option of using P2CMS because my computer is already updated with the latest quicktime (7.2). However, so far in the workflow tests I have done there hasn't been a problem.

I guess I will keep going with manually copying the contents folder until a P2CMS update comes out.
 
I used to have an issue where after about mounting 4 P2 cards on my 1.67 GHz 17" Powerbook, it would either lock up or the P2 card wouldn't show up on the desktop. I would never get more than 4 cards or so before it would lock up and I'd have to reboot.

I'm not sure what system software or what changed it but now I have no issues at all.
I've loaded dozens of cards in a row with no issues at all.

So, I'm not sure if it's a system update from Apple or if installing P2CMS did the trick.

I'm running QT 7.2 BTW.
 
So are you saying QT 7.2 is compatibile with P2CMS? I thought it wasn't. I think even on the download sight Panasonic says it is only compatible with 7.1.
 
It may not be supported by Panasonic but I've created databases etc with it while using 7.2 just fine.
